  •                  REPORTED
    IN THE COURT OF SPECIAL APPEALS
    OF MARYLAND
    No. 418
    SEPTEMBER TERM, 2015
    STANLEY ROCHKIND
    v.
    STARLENA STEVENSON
    Eyler, Deborah S.,
    Nazarian,
    Wilner, Alan M.
    (Retired, Specially Assigned)
    JJ.
    Opinion by Eyler, Deborah S., J.
    Filed: September 1, 2016
    Kevin F. Arthur, J., did not participate in the
    Court’s decision to report this opinion pursuant
    to Md. Rule 8-605.1.
    In the Circuit Court for Baltimore City, Starlena Stevenson sued S&S Partnership
    (“S&S”), Stanley Rochkind, and Dear Management & Construction Company (“Dear”)
    for negligence and violations of the Consumer Protection Act (“CPA”), Md. Code (1975,
    2013 Repl. Vol.), section 13-301 et seq. of the Commercial Law Article (“CL”).1 As
    relevant here, she alleged that she suffered injuries as a result of ingesting lead-based
    paint inside 3823 Fairview Avenue (“the Fairview Property”), which was owned by Mr.
    Rochkind and S&S and was managed by Dear.
    In March of 2014, the case was tried to a jury with Judge Steven Sfekas presiding
    (“the First Trial”). The jury returned a verdict in favor of Ms. Stevenson, awarding her
    $829,000 in economic damages and $534,000 in non-economic damages. Mr. Rochkind
    moved for a new trial or, in the alternative, a remittitur. Judge Sfekas granted the motion
    in part, ordering a partial new trial on damages.
    The partial new trial was held before a jury in October and November of 2014,
    with Judge Pamela White presiding (“the Second Trial”). The jury returned a verdict
    awarding Ms. Stevenson $753,000 in economic damages and $700,000 in non-economic
    damages.    Mr. Rochkind filed a motion for new trial, which was denied, and Ms.
    Stevenson filed a motion for attorneys’ fees, which also was denied. Applying the cap on
    non-economic damages, see Md. Code (1973, 2013 Repl. Vol.), section 11-108 of the
    1
    As we shall discuss, Ms. Stevenson also named four other defendants in her
    complaint. By the time of the trials in this matter, the only remaining active claims were
    against Mr. Rochkind, Dear, and S&S.
    Courts and Judicial Proceedings Article (“CJP”), Judge White reduced the judgment to
    $1,103,000.
    Mr. Rochkind noted this appeal, presenting eleven questions for review, which we
    have combined and rephrased as follows:
    I. Did Judge Sfekas err by ordering a partial new trial, instead of a full new
    trial, and did Judge White improperly narrow the issues to be re-tried?
    II. In the First and the Second Trials, did the court err by declining to hold a
    Frye-Reed hearing and by ruling that Cynthia Hall-Carrington, M.D., could
    testify that the Fairview Property was a substantial contributing cause of
    Stevenson’s elevated blood lead levels, that Ms. Stevenson’s ADHD was
    caused by that lead exposure, and that Ms. Stevenson lost a specific number
    of IQ points as a result of that lead exposure?
    III. In the Second Trial, did the circuit court err by not holding a Frye-Reed
    hearing to assess the methodologies employed by Mark Lieberman, a
    vocational counselor, and by permitting him to opine that, but for Ms.
    Stevenson’s “cognitive defects,” she would have functioned as an “average
    high school graduate”?
    IV. In the Second Trial, did the court err by permitting Michael Conte,
    Ph.D to offer economic loss opinions premised solely on Mr. Lieberman’s
    testimony, which should have been excluded?
    V. In the Second Trial, did the court err by precluding Mr. Rochkind’s
    economics expert from testifying about research that quantifies the loss of
    lifetime earnings caused by incremental increases in blood lead levels?
    VI. In the Second Trial, did the court err by precluding defense counsel
    from cross-examining Dr. Conte about two exhibits introduced into
    evidence by Ms. Stevenson that showed that she may have been eligible for
    free job coaching?[2]
    2
    Mr. Rochkind phrased his questions presented as follows:
    A. The lower court erred in the first trial (“Stevenson 1”) when, after
    determining post-trial that allowing Dr. Conte to testify was error, it
    ordered only a partial new trial.
    (Continued…)
    2
    (…continued)
    B. The lower courts erred by allowing Dr. Cynthia Hall-Carrington, to
    opine that lead paint from 3823 Fairview Avenue was a substantial
    contributing cause of Appellee’s elevated blood lead levels despite the
    fact that Dr. Hall-Carrington (1) is a pediatrician with no experience in
    lead risk assessment, (2) performed no investigation into other known
    lead sources, (3) did not consider or rule out other potential lead
    sources, including prior residences, concurrent visitation properties or
    ambien[t ]sources, and (4) relied exclusively on records selectively
    provided to her by Appellee’s counsel.
    C. The lower courts erred by allowing Dr. Hall-Carrington to opine that (i)
    lead exposure can cause ADHD and (ii) lead paint from Appellant’s
    property caused Appellee’s ADHD, despite the fact that the
    overwhelming opinion of the relevant medical community is that
    heredity is the primary cause of ADHD; that the medical community
    does not know whether lead exposure caused or is even associated with
    ADHD; that Appellee’s mother, brother and possibly father have all
    been diagnosed with ADHD; and that Dr. Hall-Carrington never
    examined Appellee or performed a differential diagnosis.
    D. The lower courts erred by allowing Dr. Hall-Carrington to opine that
    Appellee’s alleged injuries were caused by lead exposure at Appellant’s
    property, despite the fact that she based her opinion/diagnosis
    exclusively on epidemiological studies of the general population (which
    she admitted cannot be used to diagnose individuals); never examined
    Appellee; never performed a differential diagnosis and failed to consider
    or account for Appellee’s non-lead related problems.
    E. The lower courts erred by allowing Dr. Hall-Carrington to opine that
    Appellee lost a specific number of IQ points as the result of alleged lead
    exposure (from any and all sources) based on studies involving the
    effect of lead exposure (from any and all sources) based on studies
    involving the effect [o]f lead exposure on the general population despite
    the fact that she has no experience in IQ testing, had no foundation for
    rendering such an opinion, and two Maryland appellate courts have held
    that rendering such an opinion is error.
    F. The lower courts erred by rejecting Appellants’ request to hold an
    evidentiary pretrial hearing on Appellee’s experts (Dr. Hall-Carrington
    and Mark Lieberman) under Frye-Reed and/or Rule 5-702 to present
    expert testimony concerning the foundation, reliability and methodology
    employed by Appellee’s experts.
    (Continued…)
    3
    Ms. Stevenson noted a cross-appeal, presenting one question: Did the circuit court
    err by denying her request for attorneys’ fees?
    For the following reasons, we shall affirm the judgments of the circuit court.
    FACTS AND PROCEEDINGS
    (…continued)
    G. The first trial court erred when it granted a partial new trial on damages
    only (rather than a complete new trial), despite the fact that the issues of
    liability and damages were inextricably intertwined[.]
    H. The trial court committed error when it allowed Appellee’s vocational
    expert to opine that Appellee would have functioned as an “average
    high school graduate” but for her “cognitive deficits,” despite the fact
    that the expert had no qualifications or foundation for rendering such an
    opinion and purported to arrive at his opinion based on a methodology
    (the PEEDS-RAPEL Method) that does not purport to, and cannot be
    used to, predict educational attainment.
    I. The trial court committed error in excluding Appellant’s expert
    economist from testifying about the generally accepted scientific
    research (including the numbers used by the Centers for Disease
    Control) that quantifies the loss of lifetime earnings caused by
    incremental increases in blood lead levels to rebut the testimony of
    Appellee’s expert economist and as support for his own opinions[.]
    J. The trial court committed error when it allowed Appellee to introduce
    into eviden[c]e two exhibits “for all purposes” which showed that the
    Appellee was eligible for free job coaching, and then precluded
    Appellant from using this same evidence to cross-examine Appellee’s
    expert economist who based his loss of income calculations on the
    assumption that the Appellee would never earn any future income
    because she could not afford job coaching.
    K. The trial court committed error when it allowed Appellee’s expert
    economist to render economic loss opinions based solely on the
    opinions of Appellee’s vocational expert, which themselves should have
    been excluded.

    Ms. Stevenson was born on December 22, 1990.               Her mother, Charlena
    Montgomery, was 17 years old at the time. Ms. Stevenson was raised by her mother and
    her maternal grandmother, Lorena Cooks. Her father, Vernon Stevenson, was largely
    absent from her life. She has a maternal half-brother, who is 22, and a maternal half-
    sister, who is 16.
    From birth until age nine months, Ms. Stevenson lived with Ms. Montgomery and
    Ms. Cooks at 2110 Clifton Avenue, in Baltimore City (“2110 Clifton Property”).
    According to Ms. Montgomery, the interior walls of that property were covered with
    wood paneling, the windows were vinyl, and there was no chipping, peeling, or flaking
    (“deteriorated”) paint.
    In October of 1991, Ms. Stevenson and Ms. Montgomery moved to the Fairview
    Property, a West Baltimore rowhouse that was built in 1930. Ms. Montgomery recalled
    that the interior of the property was repainted before they moved in. The painters simply
    covered over the existing flaking and chipping paint, however, and the paint soon
    deteriorated on the interior walls.     There also was deteriorated paint on the wood
    windowsills, the ceilings, the heaters, and the front porch.
    Ms. Stevenson lived at the Fairview Property for fifteen months. During that time,
    she started walking. She liked to look out the window. Ms. Montgomery saw her
    touching the windowsills and then her mouth, and licking the windows. Ms. Stevenson
    sometimes rested her food on the windowsill and ate while standing there.
    For the first 13 months that she lived at the Fairview Property, Ms. Stevenson
    spent from 7 a.m. to 3 or 4 p.m., five days a week, at the house of a babysitter, while her
    5
    mother attended high school. The babysitter’s house was located at 2114 Clifton Avenue
    (“2114 Clifton Property”), two doors down from the 2110 Clifton Property. The 2114
    Clifton Property had been “gut rehabilitated” in 1985 and had new windows. There was
    no deteriorated paint at that property.
    In January of 1993, soon after Ms. Stevenson turned two, she and Ms.
    Montgomery moved to what Ms. Montgomery called a “newer apartment,” on
    Pennsylvania Avenue (“the Pennsylvania Avenue Property”).            According to Ms.
    Montgomery, there was no deteriorated paint at that property.
    Ms. Stevenson’s blood was tested for lead four times, beginning when she was
    almost two years old and was living at the Fairview Property, and ending when she was
    seven years old. The results were as follows:
    Date                           Blood Lead Level         Ms. Stevenson’s

    January 8, 1993                13 µg/dL                 Fairview Property

    Baltimore City or
    1809 Raynor Avenue,
    Baltimore City3
    3
    In her first amended complaint, Ms. Stevenson alleged that she lived at the
    Oxford Court address from 1996 to 1998 and at the Raynor Avenue address from 1998 to
    1999.
    6
    When Ms. Stevenson was five years old, Ms. Montgomery took her to the
    Kennedy Krieger Institute (“KKI”) for an evaluation because she was struggling to pay
    attention in school and was “hyper.” Thomas Ley, Ph.D, a KKI psychologist, determined
    that Ms. Stevenson’s cognitive functioning was within the “low average to borderline
    range,” with a full scale IQ of 76 (+/- 5). He diagnosed her with Attention Deficit
    Hyperactivity Disorder (“ADHD”), for which he prescribed Adderal, and recommended
    further testing to rule out a developmental language disorder. Ms. Stevenson remained
    on Adderal until she was 14.
    Beginning in the third grade, Ms. Stevenson was placed in special education
    classes. She was assigned a one-on-one aide who assisted her in school.
    At age 13, Ms. Stevenson attempted suicide by cutting herself and overdosing on
    prescribed medication. The following year, in April of 2005, Ms. Montgomery took Ms.
    Stevenson to the Mount Washington Pediatric Hospital (“MWPH”) for an evaluation.
    Ms. Stevenson was complaining of auditory hallucinations and depression. In May of
    2005, a psychologist at MWPH tested Ms. Stevenson and determined that she had a full
    scale IQ of 65, which is in the “Extremely Low range of ability.” She was diagnosed
    with major depressive disorder and generalized anxiety disorder.
    Ms. Stevenson never was held back in school or suspended.           In 2008, she
    graduated from high school.       She then enrolled in a Division of Occupational
    Rehabilitation (“DORS”) program for job training and coaching. Through the DORS
    7
    program, she found a job as a “transporter” for the University of Maryland Medical
    Systems. She was fired from that position, however.4
    For about 10 months in 2012 and 2013, Ms. Stevenson was employed part-time at
    a Royal Farms store, in the kitchen and at the cash register. She quit because she was
    bored. In 2014, she worked as a babysitter for her cousin’s children between the hours of
    7 p.m. and 7 a.m., earning approximately $200 every other week. At the times of the
    trials in this matter, Ms. Stevenson was unemployed.
    On December 19, 2011, Ms. Stevenson filed suit against Mr. Rochkind and the
    other defendants for negligence and unfair trade practices. The First Trial began on
    March 6, 2014. Ms. Stevenson testified and called three fact witnesses and nine expert
    witnesses in her case. Ms. Stevenson’s and Ms. Montgomery’s testimony was as we
    have recited the facts.
    Christopher White, a certified lead risk assessor for Arc Environmental, Inc.
    (“Arc”), testified that, on July 13, 2012, Arc performed x-ray fluorescence (“XRF”)
    testing on the interior and exterior surfaces of the Fairview Property. The XRF testing
    revealed 22 interior painted surfaces and nine exterior painted surfaces that were positive
    for the presence of lead-based paint. Inside the property, door jambs, window casings,
    baseboards, and door casings all tested positive. Mr. White opined that, based upon the
    age of the house, and the fact that lead-based paint has been prohibited for use in
    4
    According to Ms. Stevenson, Ms. Montgomery “got [her] fired” after she showed
    up at work to check on her.
    8
    residential properties in Baltimore City since 1978, it was more likely than not that the
    lead-based paint had been present at the Fairview Property in 1991, when Ms. Stevenson
    and Ms. Montgomery moved in.
    Robert Simon, Ph.D, an industrial hygienist, toxicologist, and lead risk assessor,
    testified, based on his review of the records in this case, that neither the 2110 Clifton
    Property, the 2114 Clifton Property, the Pennsylvania Avenue Property, nor other
    environmental lead were the source of Ms. Stevenson’s lead exposure. He explained that
    because the 2110 Clifton Property had wood paneling throughout the interior, with the
    exception of a bathroom, and had vinyl windows, any lead-based paint was “encased”
    and was not a source of lead exposure. Similarly, because the 2114 Clifton Property had
    been gut-rehabilitated in 1985, had cement steps, new carpet, and no deteriorated paint, it
    was not a source of lead exposure. He had reviewed a 2010 Arc report that showed that
    XRF testing inside the vestibule area of the Pennsylvania Avenue Property was negative
    for lead-based paint; and he knew that Ms. Montgomery had testified that the paint at the
    Pennsylvania Avenue Property was not deteriorated.5 According to Dr. Simon, this
    evidence ruled out the Pennsylvania Avenue Property as a source of Ms. Stevenson’s lead
    exposure. In light of the age of the Fairview Property, the Arc testing of that property,
    and the observed presence of deteriorating paint at that property in the 1991-1993
    5
    Because Arc was not able to enter the apartments inside the Pennsylvania
    Avenue Property, no XRF testing was performed inside the apartment where Ms.
    Stevenson had lived.
    9
    timeframe, Dr. Simon opined that there were lead-based paint hazards present at the
    Fairview Property when Ms. Stevenson lived there.
    Robert Kraft, Psy.D, a psychologist, performed a neuropsychological evaluation of
    Ms. Stevenson on August 4, 2012. Her full scale IQ was 72, which is in the “borderline
    range of general intelligence,” and her verbal IQ was 66, which is in the “extremely low
    range.” Her verbal comprehension lagged far behind her perceptual reasoning skills, an
    indication of a language-based learning disability.        Her memory and executive
    functioning skills were normal, however, and her motor functioning was above average.
    Dr. Kraft opined that Ms. Stevenson suffered from numerous cognitive deficits, including
    in general intelligence, attention, language function, visual motor functioning, and
    academic achievement. He further opined that these deficits are permanent and are likely
    to negatively affect her ability to find employment, manage her personal finances, and
    maintain social connections. (He offered no opinion about the cause of any of Ms.
    Stevenson’s cognitive deficits.)
    Cynthia Hall-Carrington, M.D., whose testimony we shall discuss in greater detail
    below, opined that the Fairview Property was a substantial contributing cause of Ms.
    Stevenson’s elevated blood lead levels. Based upon Ms. Montgomery’s answers to
    interrogatories and the Arc testing at the Pennsylvania Avenue Property, she ruled out the
    2114 Clifton Property, the 2110 Clifton Property, and the Pennsylvania Avenue Property
    as sources of Ms. Stevenson’s lead exposure. She testified that Ms. Stevenson was
    injured as a result of her elevated blood lead levels, opining that she suffered “deficits
    10
    and loss of IQ, as well as ADHD and academic decrements also.” She estimated that Ms.
    Stevenson had lost between 5 and 6 IQ points as a result of lead exposure.
    Mark Lieberman, a certified rehabilitation counselor, testified about Ms.
    Stevenson’s vocational marketability.       His ultimate opinion was that, although Ms.
    Stevenson graduated from high school, she will not function in the job market as an
    “average high school graduate.” Rather, she only will be able to obtain “basic jobs,” for
    example as a cashier or a lobby attendant, earning the minimum wage (then $7.25/hour),
    for an annual salary of around $15,000.6 Jobs of this sort are likely to be part-time, 20-30
    hours per week. In Mr. Lieberman’s view, Ms. Stevenson will require job coaching on a
    weekly basis in order to maintain employment.
    Dr. Conte, an economist, relied upon Mr. Lieberman’s expert vocational opinion
    to render an opinion about Ms. Stevenson’s potential future earnings and her loss of those
    earnings as a result of her cognitive impairments. He opined that, as an average high
    school graduate, Ms. Stevenson could have earned $1,636,458 in wages and fringe
    benefits over her lifetime. Her lifetime wages and fringe benefits as a minimum wage
    employee would be $806,753. The difference between those two figures—$829,705—
    was Ms. Stevenson’s lost future earnings.
    Mr. Rochkind testified that in 1984 he incorporated Dear and was its sole director.
    The following year, he purchased S&S and became its general partner. At that time, the
    6
    In 2014, the General Assembly enacted legislation raising the minimum wage
    over a four year period. The minimum wage went up to $8.25 per hour in July 2015, and
    will go up to $8.75 in July 2016, $9.25 in July 2017, and $10.10 in July 2018.
    11
    Fairview Property was an asset of the partnership. In 1991, Charles Runkles was hired as
    the property manager for Dear. Dear was responsible for keeping the rental properties
    owned by S&S in compliance with the Baltimore City Housing Code lead-based paint
    prohibitions.
    Mr. Runkles testified that Dear has no records about the Fairview Property from
    when Ms. Stevenson lived there. He was unable to recall whether Dear painted the
    property before Ms. Montgomery and Ms. Stevenson moved in and whether Dear
    received any complaints about the condition of the property while they lived there.
    In his case, Mr. Rochkind called three expert witnesses: Neil Blumberg, M.D., a
    forensic psychiatrist; Cynthia Munro, Ph.D, a neuro-psychologist; and Joseph Sheller,
    M.D., a pediatric neurologist.
    Dr. Blumberg reviewed Ms. Stevenson’s medical records, her deposition, and Ms.
    Cooks’s deposition. He met with Ms. Stevenson for two hours in May of 2013. He
    diagnosed her with “borderline intellectual functioning” and “major depressive
    [dis]order, single episode severe with psychotic features that is currently in full
    remission.” He opined that Ms. Stevenson’s cognitive impairment resulted from her
    home environment, coupled with genetic predisposition, and that if her IQ were 4 to 6
    points higher she still would fall within the borderline range of intellectual functioning.
    He testified that Ms. Stevenson’s “relatively mild” exposure to lead was not a substantial
    contributing factor to her cognitive impairment or to her depressive disorder.
    Dr. Munro conducted a full-day neuropsychological evaluation of Ms. Stevenson,
    on April 8, 2013, and interviewed Ms. Montgomery that day.             She measured Ms.
    12
    Stevenson’s full scale IQ to be 74, which is in the borderline range (between 70 and 79),
    and her verbal IQ to be 70. She testified that individuals within the borderline range of
    intelligence have not necessarily suffered any brain injury. The result of other tests she
    performed were not consistent with Ms. Stevenson’s having suffered a brain injury.
    Dr. Munro diagnosed Ms. Stevenson with borderline intellectual functioning and
    major depressive disorder, in partial remission. She opined that genetic factors played “a
    large role” in Ms. Stevenson’s cognitive impairment and that her evaluation of Ms.
    Stevenson revealed no evidence that she had brain damage caused by a toxic exposure.
    Dr. Munro did not diagnose Ms. Stevenson with ADHD or any attention deficit disorder.
    She explained that, because Ms. Stevenson had depression, and because depression
    affects attention, she could not make an attention deficit diagnosis. Moreover, she was
    not convinced that Ms. Stevenson ever should have been diagnosed with ADHD, given
    that the initial diagnosis at KKI was based largely on a questionnaire completed by Ms.
    Montgomery and, at the time of her diagnosis, Ms. Stevenson was not getting adequate
    sleep, which could have caused her attention difficulties.
    Dr. Sheller met with Ms. Stevenson and Ms. Montgomery a few months before the
    First Trial and reviewed Ms. Stevenson’s medical records. He diagnosed Ms. Stevenson
    with borderline intellectual functioning. Based upon his review of scientific studies
    about the neurological impact of blood lead levels similar to Ms. Stevenson’s, he opined
    that she may have lost one to two IQ points as a result of her lead exposure. He testified
    that a difference of between one and six IQ points will not have any apparent effect on
    cognitive functioning. He noted that Ms. Stevenson’s half-sister was evaluated at KKI
    13
    when she was 5 years old and that KKI could not rule out ADHD. He opined that there is
    “a very powerful genetic link” for ADHD and, given that Ms. Stevenson’s mother, half-
    brother, father, and possibly her half-sister also have attention difficulties, it is not
    surprising that Ms. Stevenson has deficits in that area.     He further opined that the
    majority of children outgrow ADHD symptoms in adulthood.
    The case was sent to the jury on a special verdict that listed the following
    questions:
    1. Do you find that [the Fairview Property] contained chipping,
    flaking, or peeling paint at the beginning of the tenancy?
    2. Do you find that [Ms. Stevenson] has proven by a preponderance
    of the evidence that there was flaking, chipping and/or peeling lead-based
    paint at [the Fairview Property] during the relevant time period?
    3. Do you find that Defendant, S&S Partnership acted negligently in
    its ownership and/or management of [the Fairview Property] during the
    relevant time period?
    4. Do you find that Defendant, Dear . . . acted negligently in its
    management of [the Fairview Property] during the relevant time period?
    5. Do you find that Defendant, . . . [Mr.] Rochkind, acted negligently
    in his ownership/operation of [the Fairview Property] during the relevant
    time period?
    6. Do you find that [Ms. Stevenson] has proven by a preponderance
    of the evidence that she suffered injury as a result of lead exposure at [the
    Fairview Property]?
    7. Do you find that [Ms. Stevenson] has proven by a preponderance
    of the evidence that she should be awarded non-economic damages?
    8. What amount of damages, if any, do you award [Ms. Stevenson]
    as damages for her non-economic losses?
    9. Do you find that [Ms. Stevenson] has proven by a preponderance
    of the evidence that she has suffered economic damages?
    10. What amount of damages, if any, do you award [Ms. Stevenson]
    as damages for economic damages?
    On March 18, 2014, the jurors returned their verdict. They answered questions 1
    through 7 and question 9 in the affirmative. On question 8, they awarded Ms. Stevenson
    14
    $539,000 in non-economic damages and, on question 10, they awarded her $829,000 in
    economic damages.
    Within ten days, Mr. Rochkind, S&S, and Dear moved to alter or amend or for a
    new trial or remittitur. As relevant here, they argued that the court erred by permitting
    Mr. Lieberman to express an opinion at trial that was not disclosed in discovery, and by
    permitting Dr. Conte to rely upon that new opinion to himself offer a new opinion. On
    April 28, 2014, the court heard argument on the defendants’ motions.7 It ruled that Dr.
    Conte’s trial testimony was a new opinion never disclosed in discovery and that its
    admission had “unfair[ly] disadvantage[d]” the defense.8 On that basis, it granted a new
    trial on economic damages. Because the jurors’ assessment of non-economic damages
    may have been “skewed” due to their award of economic damages, the court also granted
    the defendants a new trial on non-economic damages. The court ruled that the jurors’
    findings with respect to liability would stand.
    On the first day of the Second Trial, Judge White denied the defendants’ renewed
    motions in limine pertaining to Mr. Lieberman and Drs. Hall-Carrington and Conte. In
    her case, Ms. Stevenson testified and called five witnesses from the First Trial: Dr. Kraft,
    7
    On April 25, 2014, Judge Sfekas held a hearing and granted a partial new trial.
    Ms. Stevenson argued, pursuant to Rule 2-311(e), that because the court had not
    permitted her counsel to present any argument on the motions at that proceeding, it could
    not grant a partial new trial. The court agreed that it had acted improperly and vacated its
    ruling. It scheduled a new hearing on the motions for April 28, 2014.
    8
    The court did not find that Mr. Lieberman’s trial testimony included any new
    opinions not disclosed during discovery.
    15
    Mr. Lieberman, Dr. Hall-Carrington, Dr. Conte, and Ms. Montgomery. She also called
    two new lay witnesses: Alice Crowder, a DORS employee; and Jamie Weaver, Ms.
    Stevenson’s supervisor at the Royal Farms store.
    The testimony of Ms. Stevenson, Ms. Montgomery, Dr. Kraft, and Dr. Hall-
    Carrington did not differ from their testimony in the First Trial.
    Mr. Lieberman, who had met with Ms. Stevenson in the interim between the trials,
    opined, as he had at the first trial, that her cognitive deficits made her employable only in
    “very low skill positions requiring limited independent decision making, limited ability to
    read and remember information and require a high level of supervision.” These jobs
    would be part-time, involve “unskilled manual labor,” and pay “at or near minimum
    wage.” Mr. Lieberman reiterated his opinion that Ms. Stevenson would require the
    services of a job coach for “a couple hours a week” in order to maintain employment. He
    testified that a job coach typically charges $38 per hour.
    Dr. Conte offered a new economic loss opinion at the Second Trial. In making his
    calculations, he assumed that Ms. Stevenson had a work-life expectancy of 32.5 years,
    that she would be employable in minimum-wage jobs working approximately 25 to 30
    hours per week, and that she would require a job coach to maintain employment. He
    compared her lifetime earnings in that scenario to the lifetime earnings of an “African-
    American high school graduate.” Based upon those assumptions, he opined that, “absent
    the deficits” described by Mr. Lieberman, Ms. Stevenson could have earned $1,595,114
    over her lifetime. In contrast, her potential lifetime earnings with her deficits would be a
    16
    “net” “negative earnings” once the cost of job coaching was factored in. Therefore, the
    value of her lost wages and benefits was the full $1,595,114.
    Ms. Crowder is a technical specialist with DORS, who assists youths with
    disabilities to transition into adulthood. She testified that she worked with Ms. Stevenson
    for about three years, helping her to obtain training and employment. Ordinarily, once a
    DORS client finds a job and maintains employment for 90 days, the client’s case is
    closed. A DORS client who has “difficulty on the job” may contact DORS and request
    post-employment services, which might include job coaching or other services to help the
    client maintain employment. Ms. Crowder testified that Ms. Stevenson had been advised
    that she was eligible for supplemental security income (“SSI”) benefits and that that
    made her eligible for DORS services cost-free.
    Ms. Weaver testified that she worked at the Royal Farms store in Morrell Park for
    eight years and was the manager for three years, including when Ms. Stevenson worked
    there in 2012. She characterized Ms. Stevenson’s job performance as “okay,” noting that
    she “had to instruct her on what to do on a daily basis.” Ms. Stevenson’s attendance was
    “[f]air.” When Ms. Stevenson worked at the cash register, she “seemed confused, like
    she was a new employee every day.” She had a “[g]reat attitude” but did not retain skills.
    She could not be rehired at Royal Farms because the company has a “no rehire policy.”
    In his case, Mr. Rochkind again called Drs. Blumberg, Munro, and Scheller and
    also called two new witnesses: Michael Brookshire, Ph.D, an economist, and Robert
    Taylor, a rehabilitation counselor.
    17
    Dr. Blumberg’s testimony was for the most part the same as his testimony in the
    First Trial. He modified his diagnosis of Ms. Stevenson slightly, based upon records he
    had reviewed in the interim between the trials. He explained that he originally had
    diagnosed Ms. Stevenson with a single episode of major depression that was now in full
    remission, but he now believed her major depressive disorder to be recurrent.
    Drs. Munro and Scheller testified consistent with their testimony in the First Trial.
    Dr. Munro elaborated on her view that Ms. Stevenson’s impaired cognitive functioning
    was caused by her genetic predisposition, coupled with her chaotic home environment
    and depressive disorder, and not by lead exposure.
    Mr. Taylor was accepted by the court as an expert in vocational rehabilitation
    counseling. He testified, based upon Ms. Stevenson’s vocational history and Dr. Munro’s
    report, that Ms. Stevenson is capable of working full-time in a number of jobs, including
    as a food service worker, housekeeper, childcare worker, and in certain clerical jobs. In
    his view, she could earn more than the federal minimum wage in these jobs, estimating
    an income of between $18,000 and $21,000 a year. He opined that Ms. Stevenson’s
    injuries linked to her exposure to lead had not resulted in any loss in earning capacity.
    Rather, her “significant barriers” to employment arose from other “confounding
    variables” in her life.
    Dr. Brookshire testified that Ms. Stevenson had not “sustained any loss of earning
    capacity or work-life expectancy due to claimed exposure to lead” and there were
    “significant other issues that would have affected her academic and vocational
    outcomes.” He opined that there was “no difference” between Ms. Stevenson’s “pre- and
    18
    . . . post-injury earning capacity due to lead exposure” and the “total cost of additional
    rehabilitation services” required to assist her in finding full-time employment was in the
    range of $3,453 to $6,036.
    At the conclusion of all the evidence, the jurors were asked to find the amount, if
    any, of economic and non-economic damages Ms. Stevenson sustained as a result of her
    exposure to lead-based paint at the Fairview Property. On November 3, 2014, the jury
    returned a verdict awarding Ms. Stevenson $753,000 in economic damages and $700,000
    in non-economic damages.
    Within ten days, Mr. Rochkind, S&S, and Dear moved for new trial or, in the
    alternative, for a remittitur, and, on December 10, 2014, Ms. Stevenson filed a motion for
    attorneys’ fees.
    On March 18, 2015, the court entered an order denying the motion for attorneys’
    fees. Within ten days, Ms. Stevenson moved for reconsideration of that order. On June
    8, 2015, the court denied that motion.
    Meanwhile, on April 2, 2015, the court denied the motion for new trial. The court
    reduced the judgment in accordance with the cap on non-economic damages and entered
    an amended judgment in the amount of $1,103,000.
    On April 29, 2015, Rochkind noted this timely appeal. S&S and Dear did not note
    appeals.9
    9
    In her original complaint and her first amended complaint, Ms. Stevenson
    alleged exposure to lead paint hazards and resulting injury at four other properties and
    (Continued…)
    19
    (…continued)
    sued the owners of those properties as well. She alleged that the Mayor & City Council
    of Baltimore City (“Mayor & City Council”) and Edgewood Management Corporation
    (“Edgewood”), owned and/or managed the Pennsylvania Avenue Property, where she
    lived for about a year after she moved out of the Fairview Property. She alleged that the
    Housing Authority of Baltimore City (“HABC”) owned two properties located at 1308
    Hillman Street and 424 Oxford Court, where she lived from 1994 to 1996, and 1996 to
    1998, respectively. Finally, she alleged that Lawrence Polakoff owned a property located
    at 1809 Raynor Avenue, where she lived from 1998 until 1999.
    On June 19, 2012, about a month after she filed her first amended complaint, Ms.
    Stevenson filed a notice of “Partial Voluntary Dismissal Without Prejudice” as to her
    claims against the Mayor & City Council and Edgewood, neither of which had been
    served. On November 29, 2012, Mr. Polakoff was served by private process. On
    December 3, 2012, HABC was served and, on December 12, 2012, it filed an answer.
    Two months later, on February 20, 2013, Ms. Stevenson and HABC filed a joint
    “Stipulation of Dismissal Without Prejudice” as to the claims against HABC. The record
    does not reflect that the claims against Mr. Polakoff ever were dismissed.
    Ordinarily, a judgment that “adjudicates fewer than all of the claims in an action . .
    . or . . . less than an entire claim, or that adjudicates the rights and liabilities of fewer
    than all the parties to the action” is not final and appealable. Md. Rule 2-602(a). In the
    instant case, the claims against Mr. Polakoff remain outstanding and the judgment is not
    final.
    Rule 2-602(b) permits a circuit court, in its discretion, to “direct . . . the entry of a
    final judgment . . . as to one or more but fewer than all of the claims or parties” upon a
    finding that there is “no just reason for delay.” Factors relevant to the exercise of that
    discretion include: “‘a harsh economic effect’ caused by delaying the right to appeal”;
    “the danger that the same issues will have to be considered by the appellate court on
    successive appeals”; “the possibility that ‘the determination of the remaining [issues]
    before the trial court might utterly moot the need for the review now being sought’”; and
    “‘whether entertaining the present appeal upon the merits would require us to determine
    questions that are still before the trial court.’” Doe v. Sovereign Grace Ministries, 
    217 Md. App. 650
    , 667 (2014) (citations omitted).
    Pursuant to Rule 8-602(e), if this Court “determines that the order from which the
    appeal is taken was not a final judgment when the notice of appeal was filed but that the
    lower court had discretion to direct the entry of a final judgment pursuant to Rule 2-
    602(b), the appellate court may, as it finds appropriate, . . . enter a final judgment on its
    own initiative.” We exercise our discretion to do so in the instant case. The factors
    weighing against the certification of a final judgment do not apply in this case and the
    circuit court plainly would have had discretion to certify the judgment against Mr.
    Rochkind, S&S, and Dear as final. The claims against Mr. Polakoff were not a part of

    Ms. Stevenson noted a timely cross-appeal from the denial of her motion for
    attorneys’ fees and the denial of the motion for reconsideration thereof.
    We shall include additional facts as necessary to our analysis of the issues.
    APPEAL
    I.
    Partial New Trial
    In the course of this litigation, Dr. Conte prepared several reports in which he
    opined about Ms. Stevenson’s lost future earnings. In a report prepared in June of 2013,
    he calculated Ms. Stevenson’s lost future earnings to be $1,010,319. Following a pre-
    trial evidentiary hearing on January 21, 2014, the court precluded Dr. Conte from
    expressing that opinion at trial because it was based upon the Gibson & Gamboa work-
    life expectancy tables, which the court found are not generally accepted in the economic
    community. On January 22, 2014, Dr. Conte issued a new report opining that Ms.
    Stevenson had sustained $556,413 in lost future earnings. He withdrew that report,
    however, and issued his final report on February 2, 2014. In it, he calculated Ms.
    Stevenson’s lost future earnings to be $716,803. In doing so, he relied on the Millimet
    work-life expectancy tables, which he applied by placing Ms. Stevenson in the category
    for individuals having less than a high school degree.
    (…continued)
    the First Trial or the Second Trial. He was not a party to any of the pre-trial proceedings.
    We see no justification for further delaying the resolution of this appeal. Accordingly,
    we shall direct the entry of a final judgment against Mr. Rochkind, S&S, and Dear
    pursuant to Rule 8-602(e).
    21
    The defense moved to preclude Dr. Conte from expressing the opinion in his
    February 2, 2014 report at trial. The court held a hearing on the motion at the outset of
    the First Trial. It denied the motion, ruling that Dr. Conte’s use of the Millimet tables
    was permissible, but directed that he place Ms. Stevenson in the category for high school
    graduates in applying those tables.
    At trial, Dr. Conte testified that he had relied on Mr. Lieberman’s expert
    vocational opinion in reaching his opinion about Ms. Stevenson’s potential future
    earnings and loss of future earnings. Mr. Lieberman had opined that even though Ms.
    Stevenson graduated from high school, she would not be able to obtain the same jobs as
    an “average high school graduate” or command the same pay. Based on this opinion, Dr.
    Conte testified, for the first time, that
    had Ms. Stevenson not suffered from the cognitive deficits that she
    currently displays, that she would be able to compete in the labor market
    and command a salary of a typical high school graduate; but that because of
    what she’s been through, she is most likely to be working in jobs that can
    command only a minimum wage.
    Dr. Conte calculated that, “absent her current deficits,” Ms. Stevenson could earn an
    annual salary of “$29,743 with relevant growth . . . which reflects the average salary of
    an African-American high school graduate in the U.S. economy” according to federal
    government statistics. At a minimum wage job, however, Ms. Stevenson would earn just
    $15,080 annually.         He further calculated fringe benefits—including insurance,
    supplemental pay, paid leave, retirement contributions, and mandatory contributions—at
    44.3% of salary. Based on these calculations, Dr. Conte opined that, as an “average high
    school graduate,” Ms. Stevenson could have earned $1,636,459 in wages and fringe
    22
    benefits over her lifetime, but as an individual earning only the minimum wage she
    would earn $806,753 over her lifetime. The difference between those two figures—
    $829,706—was Ms. Stevenson’s lost future earnings.
    The court ruled that this opinion had not been disclosed to the defendants in
    discovery and amounted to an unfair surprise. It ordered a partial new trial, explaining as
    follows with regard to the issues to be retried:
    [T]he testimony in the case was that Ms. Stevenson had an elevated blood-
    level, that she lived at [the Fairview Property] for that period of time, and I
    think I’m not granting a new trial as to that issue. . . . .
    There will be no need, in a new trial, for testimony by either ARC or
    [Dr. Simon]. . . . .
    [The plaintiff will not] need to establish (a) that there was lead in the
    household; (b) that [Ms. Stevenson] was exposed to the lead in the
    household; (c) that she had an elevated lead level; and, (d) that the lead
    level that she had was, to a Substantial degree, the result of the exposure at
    that house. I think the jury had conclusively decided that. I’m going to let
    that portion stand.
    Therefore, the only issue that will be available for retrial will be:
    economic damages, non-economic damages and, of course, in both cases
    that will depend upon some analysis of the degree of injury to which she
    was subject. In other words, you know, the five to six point loss in IQ and
    the vocational impact that that would have had. As I said, I think there
    needs to be a proportional – some proportionate distribution of the damages
    as well, ok?
    At the outset of the Second Trial, Judge White advised the parties that she had
    reviewed the verdict sheet from the First Trial and the transcripts of the hearings on the
    motion for new trial, and it was “absolutely apparent [to her] that the issues that [would
    be] going forward to the jury [in the Second Trial were] questions numbered 8 and 10 on
    the old verdict sheet.” Those questions asked the jurors to determine the amount, if any,
    23
    of economic and non-economic damages to be awarded. Judge White stated that “[t]he
    causation issues were resolved by the first jury.”
    Mr. Rochkind (joined by S&S and Dear) argued that Judge White’s reading of
    Judge Sfekas’s ruling on the motion for new trial was too narrow. He maintained that he
    should be permitted to present evidence that Ms. Stevenson’s injuries could be the result
    of a “lot of things going on in [her] life,” not just lead exposure. He argued, moreover,
    that he should be able to present evidence and argue to the jury that Ms. Stevenson was
    not “damaged by this very modest level of lead exposure.”
    Judge White stated that she did not anticipate limiting the defendants’ right to
    cross-examine Ms. Stevenson’s experts or to present their own expert testimony bearing
    on “the nature of the injury and the severity of the injury.” She precluded Mr. Rochkind
    from relitigating the issue of “causation . . . as to whether it was the Defendants’ lead that
    caused the injury; i.e., the lead exposure and elevated blood-lead levels.” Thus, the only
    issues at the Second Trial would be “quantification of damages with attention to nature of
    injury, severity of the injury.”
    On appeal, Mr. Rochkind contends Judge Sfekas abused his discretion by granting
    only a partial new trial. He maintains that the issues of liability and damages were not
    “fairly severable,” and therefore the only effective remedy for Dr. Conte’s having
    expressed an opinion not disclosed before trial, to the prejudice of the defense, was a new
    trial on all issues. He further contends that Judge White erred by “limiting the scope of
    the [Second Trial] to damages only, despite the fact that the issues of liability and
    damages were inextricably intertwined.” He argues that he should have been permitted to
    24
    introduce evidence and argue at the Second Trial that Ms. Stevenson’s “damages were
    caused by lead from other properties or ambient sources.” (Emphasis in original.)
    Ms. Stevenson responds that Mr. Rochkind did not preserve this issue for review
    because he did not file a motion for reconsideration of Judge Sfekas’s or Judge White’s
    rulings. On the merits, she argues that the issue of damages was fairly severable from the
    liability issues, and therefore a new trial solely on damages was a proper remedy, and
    Judge White correctly limited the scope of the Second Trial to the “nature, extent, degree
    and quantification of the injuries.”
    There is no merit in Ms. Stevenson’s preservation argument. Judge Sfekas’s order
    granting a partial new trial was interlocutory and only could be challenged on appeal
    from the final judgment entered after the partial new trial. See Buck v. Cam’s Broadloom
    Rugs, Inc., 
    328 Md. 51
    , 56 (1992).         Mr. Rochkind was not required to move for
    reconsideration of the denial of his motion for new trial on liability to preserve his
    challenge to that adverse ruling. Nor was he required to move for reconsideration of
    Judge White’s ruling on the scope of the new trial to challenge that ruling on appeal.
    Rule 2-533(c) permits a court to “set aside all or part of any judgment entered and
    grant a new trial to all or any of the parties and on all of the issues, or some of the issues
    if the issues are fairly severable.” Mr. Rochkind relies on Stickley v. Chisholm, 
    136 Md. App. 305
     (2001), to support his argument that Judge Sfekas abused his discretion by
    granting a partial new trial rather than a new trial on all issues because the issues of
    liability and damages were not “fairly severable.”
    25
    In Stickley, a jury in a medical malpractice case found that the defendant doctor
    had breached the standard of care but his breach was not “the” proximate cause of the
    plaintiff’s injury. On appeal, we held that the trial court erred by instructing the jurors
    that to find in favor of the plaintiff on proximate causation the doctor’s breach had to be
    the sole cause of the plaintiff’s injury.    Invoking Rule 8-604(b), which permits an
    appellate court to reverse, in part, and affirm, in part, a judgment if it determines “that
    error affects a severable part of the action,” the plaintiff sought to have the case remanded
    for a partial new trial on causation and damages only. Id. at 316.
    We declined to do so, concluding that for this Court to remand for a partial new
    trial “‘it must clearly appear that the effect of the error did not extend to all the issues
    tried.’” Id. at 317 (quoting McBride v. Huckins, 
    81 A. 528
    , 531, 532 (N.H. 1911)). We
    observed that the jurors may have compromised by finding in favor of the plaintiff on
    breach of the standard of care and in favor of the doctor on causation; and that “the issues
    of negligence and proximate cause are . . . intricately intertwined[.]”      
    Id.
     at 317–18.
    Because it was not clear “that the effect of the erroneous jury instruction was limited to
    the issue of causation,” we remanded for a new trial on all issues. 
    Id.
     at 317–318.
    In the case at bar, the jurors in the First Trial found that Ms. Stevenson was
    exposed to deteriorated lead-based paint at the Fairview Property; the exposure was a
    substantial contributing factor causing her elevated blood lead levels; and Mr. Rochkind
    (and S&S and Dear) violated their duty of care by failing to maintain that property so
    occupants would not be exposed to deteriorated lead-based paint. Those findings and the
    evidence bearing on them were distinct from the medical issues pertaining to whether Ms.
    26
    Stevenson’s elevated blood lead levels resulted in a decrease in her IQ and in ADHD.
    Pure damages evidence, such as Dr. Conte’s expert opinion about lost future earnings,
    was even farther removed from the duty and source of lead evidence, and it was Ms.
    Stevenson’s failure to timely disclose that damages opinion that was the sole ground on
    which the new trial motion was granted. Judge Sfekas did not abuse his discretion by
    ruling that the damages issues were severable from the liability issues.
    Finally, Judge White did not misinterpret Judge Sfekas’s ruling or abuse her
    discretion in limiting the scope of the Second Trial to the issues of economic and non-
    economic damages. Mr. Rochkind was given wide latitude to present evidence bearing
    on the nature and degree of Ms. Stevenson’s injuries and their causes, including expert
    testimony of Drs. Blumberg, Munro, and Sheller that Ms. Stevenson’s impaired cognitive
    function and ADHD resulted from genetic predisposition, not from lead exposure. The
    court properly restricted Mr. Rochkind from arguing that Ms. Stevenson’s elevated blood
    lead levels, and resulting injuries, were caused by lead exposure at other properties or
    from ambient lead.
    II.
    Dr. Hall-Carrington
    Before the First Trial, Mr. Rochkind filed four motions in limine seeking to
    preclude Dr. Hall-Carrington from expressing at trial one source of lead causation
    opinion and three medical causation opinions. Specifically, he moved to preclude Dr.
    Hall-Carrington from opining that the Fairview Property was a substantial contributing
    factor in causing Ms. Stevenson’s elevated blood lead levels and from opining that Ms.
    27
    Stevenson’s exposure to lead, as manifested by her elevated blood lead levels, caused
    “cognitive defects” and “behavioral problems,” the loss of a specific number of IQ
    points, and ADHD.
    Mr. Rochkind requested Frye-Reed hearings on each motion. Judge Sfekas denied
    that request. On January 13, 2014, he heard argument on the motions in limine and
    denied them. Before the Second Trial, Mr. Rochkind renewed his motions in limine.
    Judge White heard argument on the first day of the Second Trial and denied the motions
    as well.
    A. Expert Testimony Generally
    Rule 5-702 provides that a court may admit expert testimony if the court
    determines that the testimony will assist the trier of fact to understand the
    evidence or to determine a fact in issue. In making that determination, the
    court “shall determine (1) whether the witness is qualified as an expert by
    knowledge, skill, experience, training, or education, (2) the appropriateness
    of the expert testimony on the particular subject, and (3) whether a
    sufficient factual basis exists to support the expert testimony.
    The decision to admit or exclude expert testimony under Rule 5-702 is reviewed
    for abuse of discretion. Rollins v. State, 
    392 Md. 455
    , 500 (2006). A court’s “action in
    admitting or excluding such testimony will seldom constitute a ground for reversal.”
    Bryant v. State, 
    393 Md. 196
    , 203 (2006) (citations omitted). Thus, we must uphold the
    court’s decision to admit Dr. Hall-Carrington’s opinion testimony “unless we conclude
    that [the court] acted arbitrarily or capriciously . . . or that ‘no reasonable person would
    share the view taken by the [court].’” Taylor v. Fishkind, 
    207 Md. App. 121
    , 137 (2012),
    28
    cert denied, 
    431 Md. 221
     (2013) (quoting Brown v. Daniel Realty Co., 
    409 Md. 565
    , 601
    (2009)) (alteration in Taylor).
    Expert testimony that is based on a novel scientific method also must satisfy the
    general acceptance test of Frye-Reed to be admissible. See Frye v. United States, 
    293 F. 1013
     (D.C. Cir. 1923); Reed v. State, 
    283 Md. 374
    , 389 (1978) (adopting the Frye
    standard). Under that test, the proponent of the expert testimony must show that it is
    “based on a scientific method or principle that has gained general acceptance in the
    relevant scientific community.” Ross v. Housing Authority of Baltimore City, 
    430 Md. 648
    , 660 n.10 (2013). The “general acceptance” test is an assessment of the validity and
    reliability of a given scientific method or principle. Blackwell v. Wyeth, 
    408 Md. 575
    ,
    585 (2009). If the “validity and reliability of a scientific technique [or principle] [is] . . .
    broadly and generally accepted in the scientific community,” a court may take judicial
    notice of its reliability. Reed, 
    283 Md. at 380
    . If that is not the case, “the reliability
    [must] be demonstrated before testimony based on the technique [or principle] can be
    introduced into evidence.”

            In this way, Frye-Reed is “deliberately intended to
    interpose a substantial obstacle to the unrestrained admission of evidence based upon new
    scientific principles.”

    B. Dr. Hall-Carrington’s Source of Lead Causation Opinion
    Dr. Hall-Carrington is a practicing pediatrician who has been assessing children
    for lead exposure for over twenty years. At both trials, she explained that the most
    common way in which young children are exposed to lead is by ingestion of lead-based
    paint chips, flakes, and dust.
    29
    Dr. Hall-Carrington opined that the Fairview Property was a substantial
    contributing factor causing Ms. Stevenson’s elevated blood lead levels. In preparation
    for trial, she reviewed Ms. Stevenson’s and Ms. Montgomery’s answers to interrogatories
    and deposition testimony; Dr. Simon’s report; a printout from the State Department of
    Assessments and Taxation for the Fairview Property; and the Arc report about the
    Fairview Property.     She based her source of lead opinion on Ms. Montgomery’s
    testimony that there was deteriorated paint at the Fairview Property and that Ms.
    Stevenson had engaged in hand-to-mouth activities in the vicinity of the deteriorating
    paint at that property; the Arc report confirming the presence of lead-based paint in
    numerous interior areas of that property; and Ms. Montgomery’s interrogatory answers,
    from which other possible sources of lead, including the 2114 Clifton Property, the 2110
    Clifton Property, the Pennsylvania Avenue Property, and environmental sources of lead,
    such as fishing weights and glazed pottery, could be ruled out.
    Mr. Rochkind contends that the court abused its discretion by allowing Dr. Hall-
    Carrington to opine about the source of Ms. Stevenson’s lead exposure. He complains
    that Dr. Hall-Carrington “is a pediatrician, not a lead risk assessor” and she did not
    perform any tests on the Fairview Property or “investigate other known, potential sources
    of lead exposure.” He relies upon Taylor v. Fishkind, supra, Ross v. Housing Authority,
    supra, Hamilton v. Dackman, 
    213 Md. App. 589
     (2013), cert. denied, 
    439 Md. 329
    (2014), and Roy v. Dackman, 
    445 Md. 23
     (2015), to argue that Dr. Hall-Carrington was
    not qualified to offer a lead source causation opinion because she failed to “rule out all
    other possible sources of lead.”
    30
    Ms. Stevenson responds that, as a pediatrician practicing in Baltimore City and
    assessing children for lead exposure, Dr. Hall-Carrington was qualified to opine that the
    Fairview Property was a substantial contributing cause of her elevated blood lead levels.
    She argues that Dr. Hall-Carrington’s opinion was supported by an adequate factual
    foundation because, unlike the cases on which Mr. Rochkind relies, here, there was direct
    evidence of lead-based paint in more than twenty locations inside the Fairview Property.
    That direct evidence, coupled with Ms. Montgomery’s deposition testimony and Dr.
    Simon’s report, amply supported Dr. Hall-Carrington’s opinion that the lead-based paint
    known to be present at the Fairview Property was a substantial contributing factor
    causing Ms. Stevenson’s elevated blood lead levels.
    In Roy v. Dackman, the Court of Appeals held that the trial court in a lead paint
    case did not abuse its discretion by precluding the plaintiff’s expert pediatrician from
    offering opinions at trial about the source of the lead the plaintiff was exposed to.10 In
    that case, there was no direct evidence of the presence of lead paint inside the subject
    property and the expert’s source of lead opinion “was based solely on scant
    circumstantial evidence, including the age of the home and exterior tests of the paint on
    the dwelling.” Id. at 47. The Court observed that “it is not enough for an expert to
    conclude that a certain property is the source of the child’s exposure to lead when other
    probable sources have not been eliminated”; and the expert’s proffered testimony did not
    10
    As we shall discuss below, the Court also addressed whether the trial court
    abused its discretion by precluding the same expert from testifying about medical
    causation.
    31
    rule out other probable sources. Id. at 47-48. The Court held that in the absence of direct
    evidence of the presence of lead-based paint in the subject property and of evidence
    ruling out other probable lead sources, the expert “was not competent to testify as to the
    source of [the plaintiff’s] exposure.” Id. at 47.
    The Roy Court explained that its holding regarding the expert’s competency to
    testify about source of lead was in keeping with its decision in Ross v. Housing Authority,
    supra, in which it upheld the trial court’s ruling precluding the plaintiff’s pediatrician
    expert from giving a source of lead opinion when there was no direct evidence of lead-
    based paint inside the subject property except on one stair riser; the only evidence of such
    paint on windows was for exterior windows and the expert was basing her opinion that
    lead-based paint was present at the subject property on the age of the house.
    Roy, Ross, and the other cases Mr. Rochkind relies upon to argue that Dr. Hall-
    Carrington should have been precluded from giving a source of lead opinion are
    distinguishable. Here, there was direct evidence of the presence of lead-based paint
    throughout the interior of the Fairview Property. Arc testing in 2012 revealed 22 interior
    surfaces with lead-based paint. Dr. Hall-Carrington based her lead source causation
    opinion on the direct evidence of the presence of lead-based paint in the Fairview
    Property; Dr. Simon’s opinion that because lead-based paint has been illegal to use in
    Baltimore City residences since 1978, the lead-based paint detected in the Fairview
    Property in 2012 would have been present when Ms. Stevenson was living there, and that
    the 2110 Clifton Property, the 2114 Clifton Property, and the Pennsylvania Avenue
    Property were not sources of lead paint exposure; Ms. Montgomery’s testimony that the
    32
    paint inside the Fairview Property was deteriorated when she and Ms. Stevenson were
    living there, and that she saw Ms. Stevenson put paint in her mouth; Ms. Montgomery’s
    deposition testimony from which other environmental sources of lead, such as soil,
    leaded glazed pottery, and fishing weights, could be ruled out; and her own knowledge
    and expertise as a pediatrician with experience evaluating and treating children with lead
    poisoning. Compare with Taylor, 207 Md. App. at 141–42 (court’s ruling precluding
    opinion testimony by plaintiff’s lead source expert upheld when there was no direct
    evidence of lead-based paint inside the property, evidence only of such paint on one
    exterior window, and expert’s opinion was “pure speculation”); Hamilton, 213 Md. App.
    at 589 (court’s ruling precluding plaintiff’s lead source expert opinion upheld when there
    was no direct evidence of lead-based paint in the property, there was only a positive
    finding of lead paint on an exterior transom, and the expert was assuming that lead paint
    was present due to the age of the property).
    Dr. Hall-Carrington’s expert opinion about source of lead was not a
    “transform[ation of] thin evidence or assumptions into viable causal connections.”
    Hamilton, 213 Md. App. at 608. Her opinion was grounded in fact, and the trial court did
    not abuse its discretion by admitting it.
    C. Dr. Hall-Carrington’s Medical Causation Opinions
    In preparation for the First and Second Trials, Dr. Hall-Carrington reviewed Ms.
    Stevenson’s medical and school records, Dr. Kraft’s report, and the deposition testimony
    noted above. She did not examine Ms. Stevenson or meet with her. She explained that
    33
    that was not necessary because adults who have been exposed to lead as children
    typically do not exhibit symptoms in a clinical examination.
    In her testimony in both trials, Dr. Hall-Carrington detailed the ways in which lead
    affects brain development in young children. She recounted that scientific studies have
    confirmed that there is a causal relationship between blood lead levels in excess of 10
    µg/dL in children and cognitive impairments and “externalizing behaviors.” She opined
    that Ms. Stevenson sustained “brain impairment” from her exposure to lead; that “the
    extent of her injuries [had] affected her cognitive development, as well as her academic
    level of achievement”; and that she did not have other risk factors for cognitive
    impairment, such as premature birth or head injury.          She further opined that Ms.
    Stevenson’s “cognitive defects, . . . her academic achievement, and learning disabilities,”
    as well as her ADHD, were “caused” by her exposure to lead. She explained that anxiety
    and depression also “can be associated with exposure to lead” and that Ms. Stevenson’s
    anxiety about school could have been caused by her poor academic performance and
    inability to focus. As noted, Dr. Hall-Carrington quantified Ms. Stevenson’s cognitive
    impairment, opining that she lost between five and six IQ points as a result of lead
    poisoning. A factual “basis” for her medical causation opinion was the evidence that Ms.
    Stevenson had ingested deteriorated lead-based paint at a “vulnerable age” when
    children’s brains are “more susceptible to the effects of lead.”
    1) ADHD Opinion
    In his motion in limine seeking to exclude Dr. Hall-Carrington’s opinion that Ms.
    Stevenson’s exposure to lead-based paint caused her ADHD, Mr. Rochkind argued that
    34
    there is no consensus in the scientific community about the etiology of ADHD, much less
    that exposure to lead in early childhood causes ADHD. Rather, the consensus is that
    genetics plays a major role in ADHD. In support, he cited CDC reports, information on
    the website of the National Resource Center on ADHD, a National Institute of Mental
    Health (“NIMH”) report, and an article in the Journal of Clinical Psychology, all of
    which conclude that ADHD is a condition that runs in families.           In addition, he
    referenced a 2008 article published by the American Academy of Pediatrics (“AAP”),
    which concludes that 80% of the etiology of ADHD is genetic, and described it as a
    “highly heritable disorder.”   He also cited a decision by a federal district court in
    Oklahoma excluding an expert witness opinion that lead exposure causes ADHD. See
    Palmer v. Asarco, Inc., 
    510 F. Supp. 2d 519
    , 531 (N.D. Okla. 2007).11
    In her opposition to the motion in limine, Ms. Stevenson argued that there is a
    consensus in the scientific community that exposure to lead at or above certain levels
    “causes brain injury and other behavioral changes.” In support, she relied upon a 2013
    publication by the Environmental Protection Agency entitled “Integrated Science
    11
    In Palmer, the plaintiffs, seven children exposed to low levels of lead from
    mining waste at a superfund site, designated a psychologist to testify that lead exposure
    had caused one of them to suffer from ADHD. (The others were not diagnosed with
    ADHD.) The district court held a Daubert hearing and excluded the psychologist’s
    opinion. The court emphasized that the psychologist had not identified or referenced
    “any scientific literature showing that lead exposure can cause ADHD” and had cited a
    2002 CDC study finding “no compelling evidence that an [elevated blood lead level]
    increases a child’s risk for [ADHD].” 510 F Supp. at 531 (alteration in original). The
    court noted, moreover, that the psychologist did not “state with any certainty how closely
    lead exposure and ADHD were related.” 
    Id.
     Because the psychologist did not reference
    any scientific support for her opinion, the court ruled it inadmissible.
    35
    Assessment for Lead” (“EPA-ISA”). The publication is the product of a team of scientists
    and technical experts and consists of analyses, based on peer reviewed medical
    publications and scientific studies, of the health effects of lead exposure. “The ISA
    provides a concise review, synthesis, and evaluation of the most policy-relevant science
    to serve as a scientific foundation for the review of the National Ambient Air Quality
    Standards (NAAQS).” EPA-ISA at xliv. “The fundamental process for developing an
    ISA includes . . . literature searches; . . . study selection; . . . evaluation and integration of
    the evidence; and . . . development of scientific conclusions and causal judgments.” 
    Id.
    The EPA-ISA classifies numerous health conditions associated with lead exposure
    into five categories: “Causal relationship,” “Likely to be a causal relationship,”
    “Suggestive of a causal relationship,” “Inadequate to infer a causal relationship,” and
    “Not likely to be a causal relationship.” 
    Id.
     at lxii. In Table ES-1, the publication
    provides a “[s]ummary of causal determinations for the relationship between exposure to
    Pb and health effects.” 
    Id.
     at lxxxiii. It concludes that in children there is a “[c]ausal
    relationship” between exposure to certain levels of lead and the “Externalizing
    Behaviors” of “Attention, Impulsivity and Hyperactivity.” 
    Id.
     At Section 4.3.15.2, the
    publication expounds upon that finding:
    Attention, impulsivity, and hyperactivity are evaluated together because
    they are included within the attention deficit hyperactivity disorder domain
    of externalizing behaviors (as reviewed in Whitcomb and Merrell, 2012).
    Although examined less extensively than cognitive function, a causal
    relationship between Pb exposure and attention decrements, impulsivity,
    and hyperactivity in children is supported by multiple lines of evidence: 1)
    findings from prospective studies in diverse populations for associations
    with blood or tooth Pb levels; 2) coherence with evidence in animals with
    36
    relevant Pb exposures and; 3) evidence for plausible modes of action.
    (Table 4-17).
    Id. at 4-289 (emphasis in original).
    Table 4-17, which appears at pages 4-311 through 4-323 of the EPA-ISA, details,
    in pertinent part, the associations found “from multiple, high quality epidemiologic
    studies with relevant Pb levels,” identifying the studies by author, publication, and date,
    describing the supporting evidence, and specifying the “Pb Biomarker Levels Associated
    With Effects.” Id. at 4-314. Those levels include in children “with age 30 months > 10
    µg/dL” of blood lead. The “modes of action,” meaning the ways in which lead exposure
    brings about the detrimental externalizing behaviors are the same modes by which lead
    exposure brings about cognitive function decrements: impaired neuron development;
    decrease in development of synapses; and changes in neurotransmitters.
    The table sets forth the conclusions that there is a “Causal” relationship between
    “cognitive function decrements in children” and exposure to lead at low levels (in the
    range of Ms. Stevenson’s blood lead levels); a “Causal” relationship between exposure to
    lead at low levels and “Externalizing Behaviors: Attention, Impulsivity, and
    Hyperactivity in Children”; and a “Likely Causal” relationship between “Internalizing
    Behaviors in Children,” such as anxiety and depression, and exposure to low levels of
    lead. Id. at 4-311, 4-314, & 4-317.
    Ms. Stevenson also cited in her opposition a 2005 “Policy Statement” about lead
    exposure in children by the AAP’s Committee on Environment Health. In a section of
    the Policy Statement entitled “Toxicity of Lead,” the committee states that studies show
    37
    that exposure to lead causes IQ decrements in children and affects “other aspects of brain
    or nerve function, especially behavior.” Specifically, children with “elevated tooth lead
    concentrations were more inattentive, hyperactive, disorganized, and less able to follow
    directions”; and elevated “bone lead concentrations” has been associated with “increased
    attentional dysfunction.”
    Ms. Stevenson maintained that she did not have to prove that her elevated blood
    lead levels were the only cause of her ADHD; she only had to prove substantial factor
    causation. Moreover, she was not “required to rule out every other potential source or
    cause of ADHD or brain injury.” It was sufficient for Dr. Hall-Carrington to opine that
    Ms. Stevenson’s lead exposure “contributed to her ADHD.” Finally, Ms. Stevenson
    argued that her injuries, including ADHD, are “indivisible as a matter of law.” She
    pointed to Dr. Hall-Carrington’s testimony in deposition that it is impossible to quantify
    how much of her learning difficulties are due to lead exposure and how much are due to
    social factors.
    As noted, the court denied the motions in limine. At trial, Dr. Hall-Carrington
    relied upon the studies Ms. Stevenson cited in opposition to the motions and a study
    authored by Bruce Lanphear (“the Lanphear Study”) to support her ADHD (and IQ)
    opinions.12
    12

    Children’s Intellectual Function: An International Pooled Analysis, 113 Envtl. Health
    Perspectives 894 (July 2005).
    38
    Before this Court, Mr. Rochkind offers three arguments as to why the court abused
    its discretion in admitting Dr. Hall-Carrington’s ADHD causation opinion. First, relying
    upon Blackwell, supra, he maintains that the trial court was required to hold a Frye-Reed
    hearing before ruling on the admissibility of Dr. Hall-Carrington’s ADHD causation
    opinion; and that the outcome of a Frye-Reed hearing should have been to preclude
    admission of that opinion. Second, and relatedly, Mr. Rochkind asserts that Dr. Hall-
    Carrington’s opinion as expressed at trial did not meet the threshold to prove general
    medical causation, i.e., that low level lead exposure can cause ADHD. Finally, he
    maintains that Dr. Hall-Carrington’s opinion was further deficient in that it failed to
    establish specific medical causation, i.e., that her exposure in fact caused her to develop
    ADHD. We do not find merit in any of these arguments.
    In Blackwell, the plaintiff proposed to call Mark Geier, M.D., to opine that
    thimerosal, a preservative containing ethyl-mercury that is used in certain childhood
    vaccines, can cause autism in a “subset” of neurologically vulnerable children. 
    408 Md. at 611
    . The trial court held a Frye-Reed hearing. The defendant presented the findings of
    the National Academy of Sciences’ Institute of Medicine’s (“IOM”) Committee reports
    from 2001 and 2004, the first of which concluded there is no evidence to support a link
    between thimerosal in vaccines and autism and the second of which concluded that the
    evidence favored “rejection of a causal relationship.” 
    Id. at 599
    . These findings were
    based on large scale epidemiological studies.
    Dr. Geier was prepared to opine at trial, contrary to the IOM Committee reports,
    that a causal relationship exists between thimerosal-containing vaccines and autism. The
    39
    only basis for his opinion was his own “epidemiological analysis” of publically available
    vaccine data, and the only published epidemiological studies purporting to show such a
    causal link had been undertaken by Dr. Geier and his son. 
    Id. at 600
    . Those studies had
    been strongly criticized in the scientific community and were not generally accepted or
    reliable. Moreover, the scientific consensus was that autism is genetic in etiology except
    in rare instances and that thimerosal in vaccines does not cause autism. 
    Id.
     On that basis,
    the trial court ruled at the conclusion of the Frye-Reed hearing that Dr. Geier’s causation
    testimony was not admissible.      Without Dr. Geier’s expert opinion testimony, the
    plaintiffs could not establish a prima facie case, and the case was decided in favor of the
    defendant as a matter of law.
    The case reached the Court of Appeals, which affirmed. It explained that although
    Dr. Geier’s “underlying data and methods for gathering this data [were] generally
    accepted in the scientific community,” he had “applied [that data] to support a novel
    theory.” 
    Id. at 596
    . Even if the underlying methodology was generally accepted, that did
    not “mandate acceptance of conclusions ostensibly developed therefrom.” 
    Id. at 589
    .
    The Court gave as an example Wilson v. State, 
    370 Md. 191
     (2002), in which it had held
    that an expert witness for the State in a criminal prosecution should not have been
    permitted to opine that the statistical probability of two babies in the same family dying
    from SIDS with cerebral swelling was 1 in 4 million. The opinion had been offered to
    support the State’s theory that the death of the second baby was not caused by SIDS, but
    by shaken baby syndrome, i.e., that the defendant had shaken the baby to death. The 1 in
    4 million figure was arrived at by squaring the statistical rate of one baby dying from
    40
    SIDS with cerebral swelling. The Court explained that there was a lively debate in the
    scientific community about the role of genetics in SIDS deaths and there was no scientific
    consensus that there was not a genetic component to SIDS. Thus, although the statistical
    analysis was based on sound methods, the conclusions drawn were not sufficiently
    reliable to satisfy the Frye-Reed general acceptance test.
    The Blackwell Court noted that several federal courts have been called upon “to
    scrutinize the reliability of the analytical framework utilized by an expert in formulating
    a novel theory of science.” 
    408 Md. at 605
     (emphasis in original). In General Electric
    Company v. Joiner, 
    522 U.S. 136
     (1997), the district court precluded the plaintiff’s expert
    witness from opining that the plaintiff’s small cell lung cancer was caused by PCBs and
    PCB derivatives.    The Eleventh Circuit reversed, reasoning that experts may draw
    “different conclusions from the research,” and when they do, the issue is one for the jury
    to decide. 
    Id. at 141
    . The Supreme Court granted a petition for writ of certiorari and
    reversed. Emphasizing that “conclusions and methodology are not entirely distinct from
    one another[,]” the Court held that a trial court need not “admit opinion evidence that is
    connected to existing data only by the ipse dixit of the expert. A court may conclude that
    there is simply too great an analytical gap between the data and the opinion proffered.”
    
    Id. at 146
    . Such was the case with Dr. Geier’s opinion in Blackwell that thimerosal is
    causally connected to autism.
    The only similarity between Blackwell and the case at bar is that neither one
    concerned the general reliability of a scientific method which is the usual circumstance
    calling for a Frye-Reed hearing. Otherwise, the cases are entirely distinct, and the
    41
    holding in Blackwell does not support the conclusion that the trial court in this case
    abused its discretion by not holding a Frye-Reed hearing.          Dr. Geier’s scientific
    conclusion, from his own epidemiologic studies, that the thimerisol in certain vaccines
    causes autism had been universally rejected in the scientific community and, indeed, had
    been disproven through numerous other epidemiologic studies. To this day, scientists are
    searching for the cause or causes of autism.
    By contrast, for decades, beginning in the 1970s, it has been widely accepted that
    lead exposure at levels insufficient to produce acute illness nevertheless causes
    deleterious health effects, especially cognitive deficits in children. Unlike in an autism
    case like Blackwell, where the fundamental issue is whether there is any causal
    connection between thimerisol exposure and autism, in lead paint cases such as this there
    is no controversy over the basic question whether lead paint exposure can cause health
    deficits in children. Rather, the causation disputes concern which health deficits in
    children are caused by lead exposure and the level of exposure that will produce them.
    As we have explained, Ms. Stevenson’s opposition to the motion in limine showed
    that Dr. Hall-Carrington’s ADHD causation opinion was based on epidemiologic studies,
    many of which were compiled and analyzed in the EPA-ISA and supported its finding of
    a causal link between low-level lead exposure in children and the constellation of
    symptoms that form ADHD.         Those studies used methodologies that are generally
    accepted and their conclusions were not novel in the sense used by the Court in
    Blackwell. In these circumstances, the trial court did not abuse its discretion by denying
    a Frye-Reed hearing.
    42
    Mr. Rochkind’s related argument about general medical causation is based on his
    assertion that the EPA-ISA study is not in line with the consensus in the scientific
    community that the cause of ADHD, although unknown, is primarily genetic. He points
    out that Dr. Hall-Carrington herself acknowledged that there is a “genetic component” to
    ADHD and estimated that the condition is 60% hereditary. She also acknowledged that
    she could not quantify the effect of genetics versus lead exposure on attention,
    impulsivity, and hyperactive behaviors, but only could opine that lead exposure was
    “additive.”
    Although the scientific studies and publications Mr. Rochkind cited support the
    view that ADHD is largely genetic, they do not rule out environmental causes, and some
    expressly rule in lead as a risk factor. As we have explained, the EPA-ISA and other
    studies Dr. Hall-Carrington relied upon support a causal relationship between lead
    exposure and ADHD.       The Court in Roy v. Dackman made clear that “even if [a
    particular scientific] study is contrary to the results of other studies,” the fact that an
    expert witness relies upon that study “does not invalidate the entire basis of his [or her]
    opinion.” 445 Md. at 51-52 n.16. Rather, “[s]uch is the grist for cross-examination and
    dueling experts and for resolution by the relative weight assigned by the fact-finder.” Id.
    at 52 n.16.
    With respect to specific medical causation, Mr. Rochkind argues that Ms.
    Stevenson’s family history of ADHD is a confounding factor that undermined the validity
    of any opinion that Ms. Stevenson’s ADHD was caused by exposure to lead. The trial
    court also did not abuse its discretion by permitting Dr. Hall-Carrington to testify that
    43
    Ms. Stevenson’s lead exposure was a specific cause of her ADHD symptoms. As noted,
    Dr. Hall-Carrington testified that there is a large genetic component to ADHD, but that
    lead exposure is an additive causal factor. She acknowledged that Ms. Stevenson’s
    mother had been diagnosed with ADHD, as had her half-brother. Her half-brother also
    had been exposed to lead and had elevated blood lead levels, however. Ms. Stevenson’s
    half-sister had not been exposed to lead and had not been diagnosed with ADHD. 13 The
    issue of specific medical causation in this case is governed by the substantial factor test.
    Dr. Hall-Carrington’s opinion that lead was a substantial causal factor contributing to Ms.
    Stevenson’s ADHD symptoms was supported by an adequate factual basis and was
    sufficient to allow the jury to decide the causal connection, if any, between lead exposure
    and Ms. Stevenson’s ADHD.
    2) IQ Loss Opinion
    In his motion in limine seeking to exclude Dr. Hall-Carrington’s opinion
    quantifying Ms. Stevenson’s IQ loss, Mr. Rochkind argued that the doctor’s calculations
    were not reliable under Frye-Reed and lacked an adequate factual basis under Rule 5-
    702(3). Specifically, he maintained that: 1) Dr. Hall-Carrington relied, improperly, on
    general population studies to extrapolate that Ms. Stevenson had lost a specific number of
    IQ points; 2) there is no consensus in the scientific community about a methodology for
    13
    Mr. Rochkind’s experts noted that Ms. Stevenson’s half-sister had been
    evaluated for possible ADHD as a child, but was not diagnosed due, in large part, to the
    fact that she was then sleep-deprived. Dr. Munro opined that Ms. Stevenson’s diagnosis
    of ADHD at age 5 may have also resulted from the failure to rule out confounding
    factors, such as sleep deprivation.
    44
    calculating IQ loss in a child exposed to lead; and 3) Dr. Hall-Carrington’s methodology
    of using Ms. Stevenson’s peak blood-lead level to calculate IQ loss was at odds with the
    very studies she claimed to rely upon. He attached excerpts from Dr. Hall-Carrington’s
    deposition testimony in which she could not explain why she had chosen to use Ms.
    Stevenson’s peak blood-lead level, as opposed to her lifetime average, even though the
    Lanphear Study, which she relied upon for her calculations, had used an average. She
    also could not define the term “lifetime average” as used in the Lanphear Study, noting
    that she was “not an epidemiologist.” As discussed, Judge Sfekas declined to hold a
    Frye-Reed hearing to assess the basis for Dr. Hall-Carrington’s opinions and denied the
    motion to exclude her IQ opinion.
    At both trials, Dr. Hall-Carrington testified that she had reviewed epidemiologic
    studies concerning the effects of lead on IQ decrements, and opined that there is
    “consensus among the studies that children do lose IQ points based on exposure to lead,”
    although studies “differ in the amount of IQ points that children lose.” Based on her
    review of those studies, Dr. Hall-Carrington opined that, “within a reasonable degree of
    medical certainty,” Ms. Stevenson lost between five and six IQ points as a result of her
    exposure to lead.
    On cross-examination, Dr. Hall-Carrington agreed that maternal and paternal IQ, a
    chaotic home environment, and moving between many residences and schools all are risk
    factors for cognitive impairment in children. She did not have any information about Ms.
    Montgomery’s IQ or Ms. Stevenson’s father’s IQ, but did note that Ms. Stevenson’s
    father was in special education classes during his secondary education.             She
    45
    acknowledged that she had “no way of quantifying” the effect of confounding factors, if
    any, on Ms. Stevenson’s IQ. When asked whether she used Ms. Stevenson’s peak blood
    lead level (14 µg/dL) or her average blood-lead level (11.5 µg/dL) in forming her opinion
    about the total IQ loss caused by lead exposure, she responded that, based upon the
    Lanphear Study, she used Ms. Stevenson’s peak blood lead level and calculated an IQ
    loss of 3.9 points based upon a level of between zero and ten, 0-10 µg/dL and an
    additional loss of 1.9 points for the level between 10 and 20 µg/dL, for a total of 5.8. She
    explained that her opinion would not have changed if she had used Ms. Stevenson’s
    average blood lead level.
    Mr. Rochkind argues that the trial court abused its discretion by permitting Dr.
    Hall-Carrington to opine that Ms. Stevenson lost a specific number of IQ points as a
    result of lead exposure because the doctor relied on general population studies to form
    that opinion and because she had no experience administering or interpreting IQ test
    scores. In the alternative, he argues the trial court erred by declining to hold a Frye-Reed
    hearing and/or a Rule 5-702 hearing to assess the admissibility of Dr. Hall-Carrington’s
    IQ loss opinion. He relies, primarily, on City Homes, Inc. v. Hazelwood, 
    210 Md. App. 615
    , cert. denied, 
    432 Md. 468
     (2013). Ms. Stevenson takes the position that Roy v.
    Dackman abrogated Hazelwood, and is dispositive on this issue.14
    14
    The Court of Appeals’s opinion in Roy was filed the day after Mr. Rochkind
    filed his opening brief in this Court.
    46
    In Hazelwood, the trial court in a lead paint case ruled that the plaintiff’s medical
    causation expert, Eric Sundel, M.D., a pediatrician, was qualified to testify that exposure
    to lead-based paint can cause a child to lose IQ points and that the plaintiff there had lost
    between seven and ten IQ points as a result of her exposure to deteriorating lead-based
    paint at the subject property. On appeal after a verdict in favor of the plaintiff, this Court
    reversed. We held that Dr. Sundel was not qualified to offer an expert opinion on
    medical causation because he had no relevant experience treating children for lead
    exposure; had never before testified as an expert in a lead paint poisoning case; and had
    no experience evaluating brain impairment in children who have been exposed to lead.
    We concluded that the court abused its discretion, under Rule 5-702(1), by allowing Dr.
    Sundel to “testify as to [the plaintiff]’s IQ or the loss of IQ points resulting from lead
    exposure or any alleged ‘brain impairment.’” 
    Id. at 686
    . We also found Dr. Sundel’s
    testimony that the plaintiff had lost seven to ten IQ points due to lead paint exposure to
    be “no more than speculation based on articles he read that correlated diminished IQ with
    lead exposure.” 
    Id. at 689-90
    .
    In Roy v. Dackman, one of the issues before the Court of Appeals was whether the
    circuit court had abused its discretion by precluding a pediatrician—in fact, Dr. Sundel,
    the same pediatrician as in Hazelwood—from testifying about medical causation, in
    particular, loss of IQ points resulting from childhood exposure to lead. The Court held
    that although Dr. Sundel might “not be the most qualified expert witness” on that subject,
    he was “competent . . . to testify” about it. 445 Md. at 43. The Court noted that there
    were “material differences” between the record in Hazelwood and the record in the case
    47
    before it with respect to Dr. Sundel’s qualifications. Id. at 49. It characterized as “overly
    demanding” this Court’s holding in Hazelwood that Dr. Sundel was not qualified because
    he “lacked ‘specialized knowledge concerning childhood lead poisoning, and
    specifically, the determination of the source of a child’s lead exposure and causation.’”
    Id. The Court emphasized, moreover, that since Hazelwood, Dr. Sundel had “endeavored
    to be more specific and shore-up the supposed deficiencies in his qualifications,” by
    reviewing and keeping up to date on publications about lead paint poisoning in children;
    and he had relied on the Lanphear Study, which is a well-known, although controversial,
    epidemiological study concerning IQ loss and childhood lead poisoning. Id. at 50. The
    Court concluded that the circuit court had abused its discretion by excluding Dr. Sundel’s
    medical causation opinion:
    Dr. Sundel’s academic and experiential qualifications include a three
    year pediatric residency in New York, a two year pediatric fellowship at
    Johns Hopkins University Hospital, and more than 20 years in practice.
    With this experience and as a board-certified pediatrician, Dr. Sundel was
    shown on this record to possess a sufficient background from which to
    provide an opinion as to the injuries claimed to have been suffered by [the
    plaintiff] as the result of alleged exposure to lead. Whether a jury will find
    his testimony persuasive will depend, in large measure, on the effectiveness
    of [defendants]’ cross-examination and a comparison/weighing by the jury
    against [defendants]’ competing witness(es)’ testimony.
    Id. at 52.
    It is clear from Roy that a pediatrician need not have specialized knowledge in the
    area of IQ test administration and interpretation to render a medical causation opinion
    that exposure to lead-based paint resulted in a loss of IQ points. It also is clear from Roy
    that this dispute did not trigger the need for a Frye-Reed hearing. 445 Md. at 33 n.9
    48
    (stating with respect to defense counsel’s argument that Dr. Sundel’s IQ loss opinion was
    “sheer speculation” that “[i]t is clear from the extensive medical/scientific research on the
    effects of lead paint exposure on children that expert opinions relating to this topic do not
    trigger generally the need for a Frye/Reed hearing and analysis”).
    Because, as Mr. Rochkind acknowledges, there is a scientific consensus that lead
    poisoning causes IQ loss, the only issue is whether the trial court abused its discretion by
    allowing Dr. Hall-Carrington to opine that Ms. Stevenson sustained a specific IQ loss of
    between five and six points. Dr. Hall-Carrington formed her opinion by extrapolating
    from epidemiological studies quantifying IQ loss resulting from lead exposure in the
    general population to estimate the range of IQ loss in an individual. The court accepted
    this methodology as sound. This was not an abuse of discretion. Dr. Hall-Carrington’s
    opinion that lead exposure was a substantial factor in causing the loss of a specific
    number of IQ points was not novel. See, e.g., N.B.S., Inc. v. Harvey, 
    121 Md. App. 334
    ,
    337 (1998) (noting that the evidence at trial, viewed in a light most favorable to the
    plaintiffs, showed that they lost ten IQ points and five IQ points respectively as a result of
    their exposure to lead); Berg v. Byrd, 
    124 Md. App. 208
    , 212 (1998) (noting that the
    plaintiff’s expert opined that he lost between five to ten IQ points as a result of his
    exposure to lead).
    On vigorous cross-examination, Dr. Hall-Carrington fully explained the basis for
    her calculation of the IQ loss. Although her reasons for using Ms. Stevenson’s peak
    blood level were vague, she explained that the range of IQ loss would not have differed
    had she used Ms. Stevenson’s average level. Mr. Rochkind’s experts also opined to a
    49
    range of IQ loss—albeit a smaller range—based upon Ms. Stevenson’s blood lead levels.
    Unlike Dr. Sundel’s vague and variable IQ loss opinion in Hazelwood, Dr. Hall-
    Carrington’s IQ loss opinion was supported by an adequate factual basis.
    III.
    Mark Lieberman
    Mr. Rochkind contends the trial court erred by permitting Mr. Lieberman, a
    certified rehabilitation counselor, to opine that, but for Ms. Stevenson’s cognitive
    deficits, she would have functioned in the marketplace as an “average high school
    graduate.” He complains that Mr. Lieberman was not qualified to offer that opinion and
    his methodology was unsound. Specifically, Mr. Rochkind argues that Mr. Lieberman
    assumed, improperly, that all the impairments identified in Dr. Kraft’s report were caused
    by lead exposure when Dr. Kraft did not make that determination.
    Ms. Stevenson responds that Dr. Hall-Carrington’s testimony established that the
    neuropsychological deficits Dr. Kraft identified were caused by exposure to lead-based
    paint and that Mr. Lieberman properly relied upon that testimony as the basis for his
    vocational opinion.
    Mr. Lieberman’s testimony concerned vocational marketability. He was asked to
    review Ms. Stevenson’s file after the sudden death of Martin Klitzner, a vocational
    counselor who had met with Ms. Stevenson in January of 2013. He reviewed all of Ms.
    Stevenson’s records and Mr. Klitzner’s report and also met with Ms. Stevenson in the
    interim between the First and Second Trials. He assessed Ms. Stevenson’s employment
    50
    capacity using the RAPEL method (Rehabilitation plan; Access to the labor market;
    Placeability; Earning capacity; and Labor force participation).
    Mr. Lieberman opined that Ms. Stevenson was functionally illiterate, had ADHD,
    and would require a high level of supervision and direction in the workplace. She had
    failed the entrance examinations for Baltimore City Community College and had been
    advised to take pre-remedial continuing education classes to try to improve her academic
    abilities.   Mr. Lieberman further opined that Ms. Stevenson’s low IQ, ADHD, and
    functional illiteracy all were deficits that would adversely affect her vocational
    placement. As a result of these deficits, Ms. Stevenson only would be able to find
    employment in “very low skill positions requiring limited independent decision making,
    limited ability to read and remember information and require a high level of supervision.”
    These are “unskilled manual labor” jobs that pay “at or near minimum wage.” He
    testified that she would likely only be able to work part-time. In addition, in order to
    maintain employment, she would require the services of a job coach for “a couple hours a
    week.” According to Mr. Lieberman, a job coach typically charges about $38 an hour.
    Mr. Lieberman opined that, but for her IQ loss of five to six points, Ms.
    Stevenson’s vocational abilities would have been within the “average range.” He opined
    that under the PEEDS-RAPEL method,15 vocational counselors focus on parental and
    family history in assessing the vocational prospects of the child. Ms. Stevenson’s mother
    15
    PEEDS is an acronym for: Parental/family occupations; Educational attainment;
    Evaluation results; Developmental stage; Synthesis.
    51
    (Ms. Montgomery) had graduated from high school; had been employed as an EMT; had
    obtained her CDL license; had worked as a correctional officer; and was a certified
    phlebotomist. Ms. Stevenson’s father had earned his GED; had managed a Kentucky
    Fried Chicken franchise; and had obtained his CDL license as well. Mr. Lieberman
    opined that he would expect Ms. Stevenson to perform as well or better vocationally than
    her parents, but, in light of her cognitive deficits, that was not possible. His ultimate
    opinion was that Ms. Stevenson would be limited to obtaining “basic jobs” earning the
    minimum wage (then $7.25/hour), for an annual salary of around $15,000.
    The trial court did not abuse its discretion by admitting Mr. Lieberman’s expert
    testimony about Ms. Stevenson’s vocational prospects with and without her cognitive
    deficits. Mr. Lieberman’s expertise was in the area of vocational rehabilitation. He was
    not asked to opine, nor did he opine, about the etiology of Ms. Stevenson’s cognitive
    impairment.   That issue was the subject of Dr. Hall-Carrington’s testimony.         Mr.
    Lieberman’s opinions that with her cognitive deficits Ms. Stevenson would only be able
    to attain part-time, minimum wage employment and that, but for these deficits, she could
    have achieved greater earnings typical of an average high-school graduate were
    adequately supported by facts in evidence and were not based on speculation or
    conjecture. See Lewin Realty III, Inc. v. Brooks, 
    138 Md. App. 244
     (2001), abrogated on
    other grounds by Ruffin Hotel Corp. of Md., Inc. v. Gasper, 
    418 Md. 594
     (2011).
    52
    IV.
    Dr. Conte
    In a related contention, Mr. Rochkind argues that Dr. Conte’s opinion at the
    Second Trial should have been excluded because it was premised upon Mr. Lieberman’s
    opinion, which was deficient. Because the trial court did not abuse its discretion in
    admitting Mr. Lieberman’s opinion testimony, it did not abuse its discretion in admitting
    Dr. Conte’s opinion because it was based on Mr. Lieberman’s opinion testimony.
    V.
    Dr. Brookshire
    On direct examination, Dr. Brookshire, who, as mentioned, was Mr. Rochkind’s
    economics expert, testified that Ms. Stevenson had “not sustained any loss of earning
    capacity or work-life expectancy due to claimed exposure to lead.” He then was asked
    about his familiarity with “a series of studies by medical economists on the effect of lead
    on lifetime earning capacity.” He identified three studies on that topic, one of which
    quantifies “loss of lifetime earnings related to micrograms per deciliter of blood lead
    exposure that an individual might have.” When he was asked to explain how he had used
    those figures and “updated it using appropriate economic means for present value,” Ms.
    Stevenson objected.
    At the bench, Ms. Stevenson’s counsel argued that because Dr. Brookshire’s
    opinion was that Ms. Stevenson had not sustained any loss of earnings whatsoever due to
    her lead exposure, he could not have relied on the studies quantifying the loss of earnings
    based on blood lead levels in formulating his opinion. Moreover, he had not disclosed
    53
    any opinion based upon these studies before trial. Counsel for Mr. Rochkind proffered
    that Dr. Brookshire would testify that, based upon her blood lead levels, Ms. Stevenson’s
    loss of earnings caused by lead exposure would not exceed $8,000.
    The court agreed with Ms. Stevenson, ruling that because Dr. Brookshire had not
    relied on the studies in question in formulating his expert opinion and because Dr. Conte
    also had not relied on them, the data from the studies would not be helpful to the jury and
    was not admissible under Rule 5-703(b).
    Mr. Rochkind contends this ruling was an abuse of discretion. He maintains that
    the studies were relevant to show that Dr. Brookshire’s “damages estimate was consistent
    with the existing scientific literature” and, “[m]ore importantly, [they] w[ere] offered to
    refute Dr. Conte’s opinion.” Ms. Stevenson responds that the court acted within its
    discretion to preclude Dr. Brookshire from giving an opinion at trial that was not
    disclosed in discovery and was not consistent with his disclosed opinion that Ms.
    Stevenson had not suffered any economic loss.
    Rule 5-703, entitled “Bases of opinion testimony by experts,” states:
    (a) In general. The facts or data in the particular case upon which an expert
    bases an opinion or inference may be those perceived by or made known to
    the expert at or before the hearing. If of a type reasonably relied upon by
    experts in the particular field in forming opinions or inferences upon the
    subject, the facts or data need not be admissible in evidence.
    (b) Disclosure to jury. If determined to be trustworthy, necessary to
    illuminate testimony, and unprivileged, facts or data reasonably relied upon
    by an expert pursuant to section (a) may, in the discretion of the court, be
    disclosed to the jury even if those facts and data are not admissible in
    evidence. Upon request, the court shall instruct the jury to use those facts
    and data only for the purpose of evaluating the validity and probative value
    of the expert’s opinion or inference.
    54
    (c) Right to challenge expert. This Rule does not limit the right of an
    opposing party to cross-examine an expert witness or to test the basis of the
    expert’s opinion or inference.
    The “facts or data” at issue were not “reasonably relied upon” by Dr. Brookshire
    in forming his expert opinion that Ms. Stevenson did not sustain any economic loss as a
    result of her exposure to lead. While it may have been appropriate to cross-examine Dr.
    Conte about these studies, the court did not abuse its discretion in ruling that the
    underlying calculations were not admissible in evidence by Mr. Rochkind through Dr.
    Brookshire.
    VI.
    Collateral Source Evidence
    During Mr. Lieberman’s testimony, Ms. Stevenson’s records from the DORS
    program were admitted into evidence. Certain of those records included boiler-plate
    language stating that DORS clients who are eligible for SSI or SSDI benefits are
    “excluded from participation in cost of services,” meaning that the services they receive
    through DORS are free. As mentioned, Ms. Crowder, from DORS, testified that this
    would include the cost of post-employment job-coaching to the extent a client qualifies
    for that service.
    Defense counsel sought to question Dr. Conte about the DORS records to
    determine whether, in reaching his economic loss opinion, he had considered the
    possibility of Ms. Stevenson’s receiving free job coaching through DORS. As discussed,
    Dr. Conte had opined that Ms. Stevenson’s entire future earnings would be offset by the
    55
    cost of a permanent job coach. The court heard argument and ruled that the collateral
    source rule precluded any reference to the cost of DORS services.
    Mr. Rochkind contends this was error. He argues that, even if the collateral source
    doctrine applied, once Ms. Stevenson moved the DORS records into evidence without
    any restriction on their use, he was free to use them to cross-examine Ms. Stevenson’s
    witnesses. Ms. Stevenson responds that the court properly limited cross-examination to
    prevent evidence about payment of services by an entity or individual other than the
    alleged tortfeasor.
    Maryland adheres to the rule that “an injured person [may] recover in tort the full
    amount of his provable damages regardless of the amount of compensation which the
    person has received for his injuries from sources unrelated to the tortfeasor.” Motor
    Vehicle Admin. v. Seidel Chevrolet, Inc., 
    326 Md. 237
    , 253 (1992). Free job coaching
    services from DORS are collateral source payments that are not admissible to offset
    damages.    Ms. Stevenson’s introduction into evidence of all the DORS documents,
    including those reflecting a policy not to charge clients for services if they are eligible for
    SSI or SSDI benefits, did not operate to waive the collateral source rule. The court did
    not abuse its discretion by precluding defense counsel from asking Dr. Conte if he had
    factored this collateral source into his economic loss opinion.
    CROSS-APPEAL
    Attorneys’ Fees
    The CPA “specifically prohibits any person from engaging in unfair and deceptive
    procedures in the rental or offer for rental of consumer realty.” Golt v. Phillips, 
    308 Md. 56
    1, 8 (1986). It is an unfair or deceptive trade practice for a landlord to lease property that
    is not fit for habitation, including property that contains deteriorated lead-based paint.
    See Butler v. S & S P’Ship, 
    435 Md. 635
    , 667-68 (2013). The deteriorated paint must be
    present “at the inception of a lease for the hazard to qualify as a basis for a CPA
    violation.” 
    Id. at 668
    ; see also Richwind Joint Venture 4 v. Brunson, 
    335 Md. 661
    , 685
    (1994) (“It is reasonable to assume that the General Assembly intended to limit
    application of the CPA to material misstatements and omissions at the inception of the
    lease rather than during the full term of the lease.”).
    The CPA authorizes an individual to bring a private cause of action “to recover for
    injury or loss sustained by him as the result of a practice prohibited by this title.” CL §
    13-408(a). “Any person who brings an action to recover for injury or loss under [the
    CPA] and who is awarded damages may also seek, and the court may award, reasonable
    attorney’s fees.” CL § 13-408(b). As this language makes clear, the decision to award
    fees under the CPA is discretionary.
    In this case, Ms. Stevenson’s complaint set forth claims for negligence and for
    unfair or deceptive trade practices under the CPA. In the First Trial, the jurors were
    asked whether they found “that [the Fairview Property] contained chipping, flaking, or
    peeling paint at the beginning of the tenancy?” They answered that question in the
    affirmative. Thus, the jurors found as a fact that Mr. Rochkind had committed an unfair
    or deceptive trade practice by renting the Fairview Property to Ms. Stevenson in a
    condition that was not fit for habitation.
    57
    On December 10, 2014, following the Second Trial, Ms. Stevenson filed a petition
    for prevailing party attorneys’ fees under CL section 13-408(b). She attached a copy of
    her retainer agreement with her attorneys, in which she promised to pay them a
    contingency fee equal to forty percent of any sum recovered, plus expenses. She also
    attached a “Client Expense Itemization” listing expenses totaling $135,513.81. She asked
    the court to award her the full contingency fee ($437,200) and all expenses, for a total of
    $572,713.81.
    Alternatively, Ms. Stevenson asked the court to grant her an award of attorneys’
    fees using the lodestar approach. She attached a “Time Chart” detailing work performed
    on her case by Scott Nevin, the lead attorney, and by Robert Leonard, an associate. She
    did not include time billed by paralegals and law clerks. In an attached affidavit, Mr.
    Nevin attested that when Ms. Stevenson retained him he had been licensed as an attorney
    in Maryland for nearly 30 years, half of which he had spent specializing in lead paint
    poisoning cases. Mr. Leonard had been licensed in Maryland for seven years. The time
    chart calculated hours in two time frames: the period from December 19, 2011, through
    March 17, 2014, and the period from March 17, 2014, through November of 2014. The
    chart reflected that Mr. Nevin worked on the case for 116.5 hours in the first period and
    an additional 62.75 hours thereafter; and that Mr. Leonard worked 221.25 hours in the
    first period and an additional 105.5 hours thereafter. Although the Mr. Nevin’s affidavit
    did not explain why the hours were broken into these two periods, it is clear that the first
    58
    period covers all litigation in the First Trial and the second period covers all litigation in
    the Second Trial.16
    Ms. Stevenson also attached to her petition the “Laffey Matrix” for 2014-2015.
    The Laffey Matrix, which is prepared by the Civil Division of the United States
    Attorney’s Office for the District of Columbia, suggests appropriate hourly rates for
    attorneys based upon years of experience. The Laffey Matrix for 2014-2015 suggested
    an hourly rate of $520 per hour for attorneys with more than twenty years’ experience
    and an hourly rate of $300 per hour for attorneys with between 4-7 years’ experience.
    Ms. Stevenson argued, based on the Laffey Matrix, that a reasonable hourly rate for Mr.
    Nevin was $700 per hour for the first period and $725 per hour for the second period; and
    a reasonable hourly rate for Mr. Leonard was $400 per hour for the first period and $425
    per hour for the second period.       Using these rates, she asked the court to award her
    $260,381.25 in fees plus the $135,513.81 in expenses, for a total of $395,895.06.
    Mr. Rochkind filed an opposition to the fee petition. As relevant here, he argued
    that the fee-shifting provision of the CPA is not intended to apply to personal injury
    actions that are alternatively styled as unfair trade practice actions; that Ms. Stevenson is
    not permitted to recover her contingency fee or expenses under the CPA; and that Ms.
    16
    The verdict in the First Trial was returned on March 18, 2014.
    59
    Stevenson failed to provide “sufficient information so that [the circuit court] might
    conduct the analysis it is required to conduct under Maryland law.” 17
    On January 30, 2015, the court heard argument on the petition and, on March 18,
    2015, it entered an order denying it. The court set out the guidelines for awarding
    attorneys’ fees under the CPA. It explained that the first step is to engage in a lodestar
    analysis by “‘multiplying “the number of hours reasonably expended on the litigation . . .
    by a reasonable hourly rate”’” to “‘arrive at a “useful starting point.”’” (Quoting Friolo v.
    Frankel, 
    403 Md. 443
    , 453-54 (2008) (“Friolo II”), in turn quoting Friolo v. Frankel, 
    373 Md. 501
    , 523 (2003) (“Friolo I”)). The second step is to subtract “excessive, redundant,
    or otherwise unnecessary” hours or hours “not properly billed to one’s client.” Friolo II
    at 453-54. The second step involves consideration of the factors enumerated in Rule 1.5
    of the Maryland Lawyers’ Rules of Professional Conduct (“MLRPC”) governing fees
    charged.18
    The court found that, in light of the jury’s answer to the first question on the
    special verdict sheet at the First Trial, Ms. Stevenson was a prevailing party on her CPA
    17
    In his opposition and in his motion for new trial, Mr. Rochkind argued that the
    CPA claim should not have been submitted to the jury at the First Trial because Ms.
    Montgomery testified that the property was freshly painted at the inception of the
    tenancy. He does not advance that argument on appeal.
    18
    Those factors include “the time and labor required,” “the novelty and difficulty
    of the questions involved,” and the “likelihood, if apparent to the client, that the
    acceptance of the particular employment will preclude other employment of the lawyer,”
    and “the experience, reputation, and ability of the lawyer or lawyers performing the
    services.” Md. Rule 16-812, MLRPC 1.5.
    60
    claim. It also found that “[h]er claims of negligence and violation of the CPA, which
    yielded successful jury verdicts in both trials, arose from ‘a common core of facts’ and
    ‘related legal theories.’” (Quoting Friolo I, at 524). In the court’s view, the “causes of
    action [negligence and the CPA violation] essentially were indivisible in the presentation
    of operative facts during the [F]irst [T]rial” and “there was no differentiation between the
    two causes of action in terms of proof and determination of damages” in the Second
    Trial.    The court also determined that only attorneys’ fees, not expenses or fees
    attributable to non-attorneys, may be awarded under the CPA.
    Turning to whether a fee award was appropriate, the court found that the “Time
    Chart” and the Nevin Affidavit were too vague for it to apply the lodestar method. The
    Time Chart did not “state the actual time or describe the tasks undertaken to investigate
    [Ms. Stevenson’s] claims, communicate with the client and witnesses, draft pleadings,
    review other parties’ pleadings, prepare interrogatories, request document production,
    prepare for depositions, engage in motions practice, attend court hearings for particular
    purposes, or address alternative dispute resolution.”
    The court also took issue with Ms. Stevenson’s use of the “Laffey Matrix,” noting
    that it is “a mechanism for calculating reasonable attorney’s fees in Washington, D.C.,”
    not in Baltimore. The court observed that the hourly rates listed in Appendix B to the
    Local Rules of the United States District Court for the District of Maryland are “more apt
    61
    and comparable.”19       Finally, the court concluded that it could not assess the
    reasonableness of the fee request because the Nevin Affidavit did not address “whether
    and how he was prevented from taking on any new cases by the inconvenience of
    conducting the two trials in this case.”
    For all these reasons, the court determined that Ms. Stevenson had not “provide[d]
    sufficient information to allow th[e] court to make the reasoned and well supported
    analysis required” for an award of fees; nor did the docket entries provide “specific
    information as to what an appropriate fee might be.” The Nevin Affidavit and the Time
    Chart “offer[ed] some information as to some of the enumerated factors” but failed “to
    offer sufficient detail to satisfy many of the remaining criteria.” Due to the lack of
    information, the court found itself unable to “inject some reasonableness into fees sought
    by [Ms. Stevenson’s] counsel.” It thus denied the petition for fees.
    Within ten-days of the entry of that order, Ms. Stevenson moved for
    reconsideration. She argued that the court abused its discretion by denying the fee
    petition because it did not exercise any discretion in doing so. She emphasized that the
    court had discretion to assess the reasonableness of the hourly rates and to lower the rates
    requested, such as by applying rates consistent with Appendix B. She maintained that
    19
    Section 3 of Appendix B sets forth “Guidelines Regarding Hourly Rates.” For
    the period between July 1, 2011 and June 30, 2014, the guideline rate for lawyers
    admitted to the bar for between five to eight years was $165-250 per hour and for lawyers
    admitted to the bar for 15 years or more was $275-400 per hour. Effective July 1, 2014,
    the lower range was amended to between $165-300 per hour and a new guideline range
    was added for lawyers admitted to the bar for 20 years or more of $300-475 per hour.
    62
    Mr. Leonard and Mr. Nevin were entitled to the hourly rate at the high end of the ranges
    provided in Appendix B ($300 per hour for Mr. Leonard and $475 per hour for Mr.
    Nevin). She maintained that the court failed to exercise its discretion when it did not even
    calculate a lodestar figure and assess the reasonableness of the fees sought under that
    methodology.
    By order entered on June 8, 2015, the court denied the motion for reconsideration.
    It noted that Ms. Stevenson did not take issue with the court’s legal analysis, but with the
    application of the law to the facts. It reiterated that the Time Chart failed to distinguish
    between time spent on the CPA claim and time spent on the negligence claim.               It
    concluded that, “[w]ithout evidence sufficiently detailing the time [Ms. Stevenson]’s
    attorneys spent on the entire case, let alone the CPA claim,” the court “would be
    engaging in speculation for the ‘number of hours reasonably expended’ portion of the
    reasonable fee analysis.” Thus, even if the court had been able to determine a reasonable
    hourly rate, it was unable, with the information furnished, to “engage in the case-specific,
    detail-oriented, and thorough analysis required in order to grant an award of attorneys’
    fees.”
    On appeal, Ms. Stevenson contends the circuit court abused its discretion by not
    awarding her any attorneys’ fees under the CPA. She maintains that the court failed to
    exercise any discretion to “determine a reasonable hourly rate based on [its] own
    knowledge and experience,” coupled with the Laffey Matrix and Appendix B. And,
    having found that the CPA claim and the negligence claim were “essentially . . .
    63
    indivisible,” the court abused its discretion by not awarding her attorneys’ fees for “all of
    the time that counsel spent on the litigation.”
    Mr. Rochkind responds that the court properly exercised its discretion to deny the
    fee petition because Ms. Stevenson failed to present adequate proof of the appropriate
    hourly rate and the number of hours reasonably expended on her CPA claim. With
    respect to the hourly rate, he maintains that Ms. Stevenson had to “provide specific
    evidence, such as expert testimony or affidavits demonstrating that attorneys with similar
    qualifications have received in the past the same fees for similar work conducted in the
    same jurisdiction.” This was especially so given that her counsel had not provided any
    explanation for how they had arrived at the requested hourly rates, which far exceeded
    the amounts shown on the Laffey Matrix.           With respect to the hours reasonably
    expended, Mr. Rochkind asserts that the Time Chart was “entirely inadequate,” both
    because it lacked sufficient detail and because it failed to “segregate the time spent on the
    CPA claim from the time spent on other claims.” Alternatively, he argues that an award
    of fees is not appropriate in a case of this type because it is a personal injury action and
    because it is impossible to divine from the verdict in the First Trial whether the jury
    awarded damages for violation of the CPA or on the negligence claim.
    In Richwind, 
    335 Md. at 687
    , the Court of Appeals expressed doubt that an award
    of attorneys’ fees under section 13-408(b) of the CPA would be appropriate in a case like
    the one at bar:
    The instant case is fundamentally a personal injury action. It is
    questionable whether the legislature intended to abrogate the long-standing
    rule that attorney fees are not recoverable in personal injury actions, and to
    64
    permit plaintiffs who recover tort damages for personal injuries also to
    recover attorney fees in such actions by bringing them under the CPA.
    Based on our holding that the CPA is not applicable, we need not reach the
    issue of whether attorney’s fees could properly be awarded in a personal
    injury tort action based on an additional count which alleges the tort was
    also a violation of the CPA.
    Like in Richwind, in this case, Ms. Stevenson prosecuted a quintessential personal
    injury action, but alleged that “the tort was also a violation of the CPA.” We need not
    decide whether an award of prevailing party fees ever would be appropriate in such an
    action, however, because we conclude that the trial court did not abuse its discretion by
    denying the petition in any event.
    Putting aside that Ms. Stevenson requested an award of her total contingency fee
    and an award of expenses, both of which are plainly prohibited, she asked, in the
    alternative, for the court to use the lodestar method and apply hourly rates that were not
    supported by any evidence. The beginning rate proposed for Mr. Nevin was $700 per
    hour, $180 per hour more than the rate in the Laffey Matrix and $225 per hour more than
    the high end of the range in Appendix B for an attorney with his experience. The
    beginning rate proposed for Mr. Leonard—$400 per hour—exceeded the Laffey Matrix
    rate and the high end of the Appendix B rate by $100 per hour. Ms. Stevenson did not
    present any evidence to justify the use of the Laffey Matrix for a case tried in Baltimore
    City or to justify an upward departure from those rates.             In her motion for
    reconsideration, she argued that the court should have applied Appendix B, but did not
    65
    offer any explanation as to why her counsel were entitled to fees at the high end of the
    applicable ranges.20
    And most significantly, Ms. Stevenson did not provide evidence from which the
    court could determine the number of attorney hours reasonably expended on Ms.
    Stevenson’s CPA claim. The Time Chart lacks the detail to do so. For example, as
    mentioned, Ms. Stevenson originally sued four other defendants. The Time Chart does
    not specify and segregate hours spent investigating the claims against those defendants.
    Ms. Stevenson’s proof that there was deteriorated lead-based paint at the inception of her
    tenancy at the Fairview Property—all that was needed to establish the CPA violation—
    was Ms. Montgomery’s and White’s testimony to that effect. Had the jurors found
    against her on that issue, it would not have been fatal to her remaining negligence claim,
    which was premised on Mr. Rochkind’s being on notice of the existence of deteriorated
    lead-based paint at any time during her tenancy. As Judge White found, however, Ms.
    Stevenson made no attempt to separate out the hours spent developing and presenting
    evidence on the discrete CPA claim from the hours spent on the bulk of this personal
    injury negligence action. Given the dearth of evidence that would allow the court to
    assess the reasonableness of the attorney hours spent in prosecuting the CPA claim, the
    court did not abuse its discretion in denying the fee petition.
    20
    Ms. Stevenson also did not explain why the hourly rates for Mr. Leonard and
    Mr. Nevin during the period between December 2011 and June 2014 should not have
    been calculated under Appendix B to the then applicable Local Rules, which would have
    reduced the high end amount for Mr. Leonard from $300 to $250 and the high end
    amount for Mr. Nevin from $475 to $400.
