    OWEN ROGAL
    Appellant                         No. 5 EDA 2014
    Appeal from the Judgment of Sentence November 18, 2013
    In the Court of Common Pleas of Philadelphia County
    Criminal Division at No(s): CP-51-CR-0002115-2012
    BEFORE: PANELLA, J., OTT, J., and JENKINS, J.
    OPINION BY OTT, J.:                                           FILED JULY 07, 2015
    Dr. Owen Rogal appeals the judgment of sentence entered November
    18, 2013, in the Philadelphia County Court of Common Pleas. The trial court
    sentenced Rogal to a term of one to seven years’ imprisonment after a jury
    found him guilty of 31 charges, including corrupt organizations, conspiracy,
    theft by deception, attempted theft by deception, and insurance fraud. 1 The
    jury    determined     Rogal    and    his     daughter,   co-defendant   Kim   Rogal,
    intentionally and systematically used an improper billing code to collect
    higher payments from insurance companies for procedures performed in
    their pain clinic. On appeal, Rogal contends (1) the evidence was insufficient

    to support the verdict; (2) the trial court failed to act as gatekeeper when it
    permitted the dual testimony of Commonwealth witness, Frank J. Dubeck,
    Jr., M.D., as both a lay witness and an expert witness; and (2) the court
    erred in failing to determine that Rogal’s attorney operated under a conflict
    of interest. For the reasons below, we affirm.
    The facts underlying Rogal’s conviction are as follows. Rogal and his
    daughter, Kim Rogal, owned and operated The Pain Center (“TPC”), a clinic
    that specialized in performing radiofrequency surgery (“RFS”) to relieve
    pain.    Rogal, a dentist by trade, supervised the doctors employed by TPC
    and interviewed prospective patients, while Kim Rogal was the office
    manager and ran the billing department.2         Kim Rogal also developed the
    computerized billing program TPC used to bill insurance companies for the
    RFS procedure.
    RFS is a simple, “low-risk” procedure, performed in an office suite,3
    that uses “high-intensity heat” to reduce pain. N.T., 4/23/2013, at 20, 89.
    At TPC, a doctor would apply a local anesthetic to numb the area on the
    patient, and then insert a needle, guided by a fluoroscope,4 to administer

    Kim Rogal also owned the building out of which TPC operated.            N.T.,
    4/25/2013, at 40.
    3
    The RFS performed at TPC did not require either a sterile room or an
    anesthesiologist. N.T., 4/23/2014, at 22, 111.

    heat to a small area to stop the pain.             See 
    id. at 31-38.
       The doctors
    working at TPC did not receive any specialized training, but rather, simply
    observed other physicians performing RFS for a few days before attempting
    the procedure themselves. 
    Id. at 15.
                Dr. John Paul Palmerio, who worked
    at TPC from November of 2004 until March of 2012, testified the doctors at
    TPC “worked strictly on bone” to relieve pain in the “cervical spine, thoracic
    spine, lumbar spine, hips, on a knee, or on a[n] elbow[.]” 
    Id. at 23.
    Since 1990, TPC has been billing insurance companies for the RFS
    procedure using standard billing code 61790 (“CPT Code 61790”).5                  In
    layman’s terms, CPT Code 61790 refers to “destroying tissue with precise
    locational control by sticking something through the skin that destroys the
    nerve of the gasserian ganglion.”          N.T., 4/22/2013, at 75.     The gasserian
    ganglion, located in the “cranial vault,” is “one of the 12 cranial nerves in the
    brain,” and “supplies sensation to the face and taste to the anterior two-
    thirds of the tongue.”6       
    Id. at 69.
          The procedure described in CPT Code

    The Current Procedural Terminology (“CPT”) Manual contains standardized
    billing codes for all medical procedures, which enables insurance companies
    to process claims electronically. N.T., 4/22/2013, at 50-51. The CPT
    manual is created by physicians and updated annually. 
    Id. at 52.
    Dr.
    Dubeck, an expert in medical billing and coding, testified that insurance
    companies take the code submitted by the medical professional “at face
    value” so that most claims are processed by the computer and
    reimbursements are paid within a few weeks. 
    Id. at 59.

    Dr. John Lee, an expert in neurosurgery, testified the cranial nerves are “a
    very intricate anatomy and you spend many years studying this anatomy to
    operate on it safely.” N.T., 4/25/2013, at 14.
    -3-
    J-A06024-15
    61790 is a “very delicate” procedure which is usually performed by a
    neurosurgeon       in    an   operating        room   with   the   assistance   of   an
    anesthesiologist.       
    Id., at 70;
    N.T., 4/25/2013, at 21. It is used as a last
    resort to treat patients with trigeminal neuralgia, “a debilitating facial pain.” 7
    N.T., 4/22/2013, at 88. While the procedure described in CPT Code 61790 is
    similar to the RFS procedure performed at TPC, that is, a doctor sticks a
    needle through the skin to destroy nerves, the doctors at TPC never
    performed procedures near the brain.8
    Nevertheless, TPC always billed its low-risk RFS procedure using CPT
    Code 61790, which had a reimbursement value of $4,800. N.T., 4/23/2013,
    at 51, 54-55.       Whereas, the typical reimbursement value for the actual
    procedure performed at TPC was $300 to $400.                 
    Id. at 109.
      During the
    course of the subsequent investigation, the Commonwealth determined that
    TPC billed 12 insurance companies in excess of $5,000,000.00 under CPT
    ____________________________________________
    7
    Dr. Lee explained the pain suffered by patients with trigeminal neuralgia is
    so severe that “[s]ome people have even termed it the suicide pain” because
    it almost drives patients to suicide. N.T., 4/25/2013, at 11.
    8
    Coding expert, Dr. Dubeck, explained the CPT Code Manual specifically
    instructs physicians to “accurately identify the service performed” and not to
    “merely approximate[] the service performed.” N.T., 4/22/2013, at 79. The
    Manual states “[i]f no such specific code exists, then report the service using
    the appropriate unlisted procedure or service code.” 
    Id. To that
    end, Dr.
    Dubeck testified TPC committed a “direct violation of the coding instructions”
    when they billed their RFS procedure at CPT Code 61790 simply because
    their procedure “met four out of five elements of [that] code[.]” 
    Id. at 102.
    -4-
    J-A06024-15
    Code 61790.9         N.T., 4/24/2013, at 108.           Furthermore, although the
    Commonwealth’s expert neurosurgeon testified it would be rare for a patient
    to undergo the procedure at CPT Code 61790 more than once, TPC billed
    insurance companies for as many as 78 treatments for the same patient.
    See N.T., 4/24/2013, at 116-117; N.T., 4/25/2013, at 31.
    Eventually, the insurance companies began flagging claims submitted
    by TPC.       See N.T., 4/22/2014, at 123 (Blue Cross Excellus); N.T.
    4/24/2013, at 20 (Horizon Blue Cross Blue Shield of New Jersey); 75
    (Aetna). In 2005, both Horizon and Aetna notified TPC that its use of CPT
    Code 61790 was improper for the procedure actually performed.                  Ann
    Browne, Senior Investigator for Horizon, testified that after meeting with
    TPC’s attorney, Kevin Rafeal, she obtained 12 peer reviews, per his request,
    which all confirmed that CPT Code 61790 was not appropriate for the
    procedure performed at TPC.             N.T., 4/24/2012, at 15.      Although she
    informed Rafeal of the coding problem in 2006, TPC continued to bill Horizon
    for CPT Code 61790, using the individual physician’s taxpayer ID numbers
    until June of 2010.          
    Id. at 22.
           Similarly, Elizabeth Saragusa, fraud
    investigator for Aetna, testified that Aetna began flagging TPC claims in
    2004. 
    Id. at 75.

    The records revealed, however, that the insurance companies paid only
    $1.8 million in reimbursements for the amount billed. N.T., 4/24/2013, at
    109.

    Dr. Stuart Kaufmann began working for TPC in late 2004.       About a
    year later, he was contacted by a Blue Cross representative, who informed
    him of the billing code discrepancy. N.T., 4/23/2013, at 101. Dr. Kaufmann
    testified at trial that he was angry because he feared he might lose his
    medical license. 
    Id. at 102.
    He stated he confronted Rogal who responded
    as follows:
    He tried to reassure me that he had really good attorneys who
    said that the procedure [was] billed correctly, and not to worry,
    and I am making something out of nothing, that insurance
    companies for years have been trying to take him down. It was
    just more of a witch hunt is basically what he told me.
    
    Id. at 103.
      Dr. Kaufmann then spoke with TPC’s attorney, Kevin Rafeal,
    regarding his concerns about the legality of the code.            After that
    conversation, Dr. Kaufmann left TPC.
    In February of 2005, another TPC physican, Dr. John Paul Palmerio,
    received a similar letter from Highmark Insurance Company questioning his
    submission of bills using CPT Code 61790.     
    Id. at 52,
    57.    Dr. Palmerio
    spoke with Kim Rogal the next day.     She told him “not to worry” because
    “[t]hese people are not allowed to do what they are doing.” 
    Id. at 60.
    She
    also told him she was “turning it over to the lawyers who [would] write
    [him] a letter regarding this matter.” 
    Id. Dr. Dubeck,
    who was medical liaison to the fraud unit for Blue Cross
    Excellus, testified that his company was notified by another Blue Cross plan
    -6-
    J-A06024-15
    to take a “closer look” at the TPC bills.10          N.T., 4/22/2013, at 67.    His
    investigation revealed the billing code TPC used was for “brain surgery,” but
    the procedure actually performed “was nowhere near the brain.” 
    Id. at 68.
    Blue Cross Excellus began flagging TPC’s claims in September of 2009. In
    response to an appeal by TPC, Dr. Dubeck sent Kim Rogal a detailed letter
    on December 18, 2009, in which he explained the use of CPT Code 61790 for
    the RFS procedure performed at TPC was incorrect and provided two
    alternative codes for the procedure performed. 
    Id. at 170-173.
    However,
    despite having advised Kim Rogal “in no uncertain terms … not to bill
    [Excellus] using the code 61790 ever again[,]” Execellus received at least six
    subsequent bills from TPC in 2010 with CPT Code 61790. 
    Id. at 174-175.
    Additionally, in late 2009, the Philadelphia District Attorney’s Office
    received a referral regarding TPC’s fraudulent billing practices from the
    National Insurance Crime Bureau.               After further investigation, District
    Attorney Detective Karl Supperer secured a search warrant for TPC, which
    he executed on November 22, 2010. A 15-month grand jury investigation
    followed, after which the Commonwealth charged Rogal and his daughter
    with multiple crimes, including corrupt organizations, conspiracy and
    insurance fraud.11       On February 16, 2012, the trial court granted the

    Commonwealth’s motion to bypass a preliminary hearing and proceed to
    trial.
    On May 1, 2013, a jury returned a verdict of guilty on all charges
    against both Rogal and Kim Rogal.                Prior to sentencing, Cheryl J. Sturm,
    Esq., entered her appearance on behalf of Rogal.               On October 22, 2013,
    counsel filed a motion for extraordinary relief challenging, inter alia, the
    sufficiency of the evidence, several evidentiary rulings and a potential
    conflict of interest regarding trial counsel’s representation.         The trial court
    denied the motion without a hearing on November 5, 2013. On November
    18, 2013, the court imposed concurrent sentences of one to seven years’
    incarceration on each of Rogal’s 31 convictions.12 Rogal filed a timely post
    sentence motion and a motion for modification of sentence, both of which
    the trial court denied without a hearing. This timely appeal follows. 13

    at 10-11. They were represented by the same attorney during the grand
    jury proceedings, but retained separate counsel after the charges were filed.
    See N.T., 3/7/2012.
    12
    The court sentenced Kim Rogal to concurrent terms of 11½ to 23 months’
    of house arrest, followed by five years’ reporting probation on each of her 31
    convictions. N.T., 11/18/2013, at 58.
    13
    The trial court did not order Rogal to file a concise statement of errors
    complained of on appeal pursuant to Pa.R.A.P. 1925(b), and the court’s Rule
    1925(a) opinion addressed only Rogal’s request for bail pending appeal.
    Thereafter, the Commonwealth filed an application requesting this Court
    remand the appeal to allow the trial court to file an opinion addressing the
    claims raised by Rogal in his appellate brief (“Rogal’s Principal Brief”). We
    granted the Commonwealth’s request on May 21, 2014, and directed Rogal
    to file a Rule 1925(b) statement. Upon remand, Rogal filed a lengthy (20-
    (Footnote Continued Next Page)
    -8-
    J-A06024-15
    In his first issue on appeal, Rogal challenges the sufficiency of the
    evidence supporting his convictions of corrupt organizations and conspiracy.
    With respect to the corrupt organizations charge, Rogal argues that there is
    no evidence he committed a predicate act of racketeering.      Further, with
    respect to the conspiracy charge, he contends he was found guilty by
    association.   Specifically, Rogal asserts there was no evidence he had a
    shared criminal intent with his daughter to defraud the insurance companies.
    Rather, he argues, the evidence demonstrates he had no involvement in the
    billing process, which was handled exclusively by Kim Rogal, and the jury
    improperly inferred a conspiracy based solely on their father/daughter
    relationship. He also maintains the remaining convictions were tarnished by
    the stigma of the corrupt organizations charge.
    Our review of a challenge to the sufficiency of the evidence is well-
    established.
    We review the evidence in the light most favorable to the verdict
    winner to determine whether there is sufficient evidence to allow
    the jury to find every element of a crime beyond a reasonable
    doubt.
    In applying the above test, we may not weigh the evidence
    and substitute our judgment for the fact-finder. In
    addition, we note that the facts and circumstances
    established by the Commonwealth need not preclude every
    _______________________

    page) concise statement, and the trial court filed an opinion in response.
    Thereafter, this Court granted Rogal’s request to file a Supplemental
    Opening Brief in response to the court’s opinion (“Rogal’s Supplemental
    Brief”).

    possibility of innocence.      Any doubts regarding a
    defendant’s guilt may be resolved by the fact-finder unless
    the evidence is so weak and inconclusive that as a matter
    of law no probability of fact may be drawn from the
    combined circumstances. The Commonwealth may sustain
    its burden of proving every element of the crime beyond a
    reasonable doubt by means of wholly circumstantial
    evidence. Moreover, in applying the above test, the entire
    record must be evaluated and all evidence actually
    received must be considered. Finally, the finder of fact
    while passing upon the credibility of witnesses and the
    weight of the evidence produced, is free to believe all, part
    or none of the evidence.

    , 792-793 (Pa. Super. 2015)
    (citation omitted).
    The crime of corrupt organizations is codified at Section 911 of the
    Crimes Code, which provides, in relevant part:
    It shall be unlawful for any person employed by or associated
    with any enterprise to conduct or participate, directly or
    indirectly, in the conduct of such enterprise’s affairs through a
    pattern of racketeering activity.
    18 Pa.C.S. § 911(b)(3). It is also unlawful for a person to conspire to violate
    subsection (b)(3). 
    Id. at §
    911(b)(4). Subsection (h) defines “enterprise”
    as “any … corporation, association or other legal entity, … engaged in
    commerce and includes legitimate as well as illegitimate entities and
    governmental entities.”   
    Id. at §
    911(h)(3).    Further, the subsection lists
    numerous crimes that constitute “racketeering activity,” including theft and
    insurance fraud, and defines a “pattern of racketeering activity” as “a course
    of conduct requiring two or more acts of racketeering activity one of which
    - 10 -
    J-A06024-15
    occurred after the effective date of this section.”    
    Id. at §
    § 911(h)(1),
    (h)(4).
    With regard to Rogal’s conspiracy conviction, we note:
    To sustain a conviction for criminal conspiracy, the
    Commonwealth must establish the defendant: 1) entered into an
    agreement to commit or aid in an unlawful act with another
    person or persons; 2) with a shared criminal intent; and 3) an
    overt act was done in furtherance of the conspiracy.          The
    conduct of the parties and the circumstances surrounding such
    conduct may create a web of evidence linking the accused to the
    alleged conspiracy beyond a reasonable doubt.                 The
    conspiratorial agreement can be inferred from a variety of
    circumstances including, but not limited to, the relation between
    the parties, knowledge of and participation in the crime, and the
    circumstances and conduct of the parties surrounding the
    criminal episode.

    , 25-26 (Pa. Super. 2013)
    (citation and internal punctuation omitted), appeal denied, 
    81 A.3d 75
    (Pa.
    2013).
    Here, the trial court concluded there was sufficient evidence to support
    Rogal’s convictions beyond a reasonable doubt. First, the court detailed the
    evidence demonstrating “a patent dissimilarity” between the “simple, low
    risk, pain relief procedure” performed at TPC, and the “brain surgery” billed
    at CPT Code 61790.      Trial Court Opinion, 8/28/2014, at 3-4.      The RFS
    procedure performed at TPC was described as “relatively straightforward and
    safe.” 
    Id. at 3.
    Most of TPC’s physicians began performing the procedure
    after less than a week of observation. 
    Id. It required
    no special training, no
    anesthesiologist, and no sterile operating room. 
    Id. at 3-4.
    Conversely, the
    - 11 -
    J-A06024-15
    procedure billed at CPT Code 61790 was within the brain surgery billing
    category, and performed “almost exclusively by neurosurgeons.” 
    Id. at 3.
    Expert neurosurgeon Dr. Lee testified that the procedure required “extensive
    training” and required both an attending anesthesiologist and sterile
    operating room. 
    Id. The trial
    court also noted that the “patent dissimilarity”
    between the two procedures is even more evident when considering the
    reimbursement value.     
    Id. at 4.
       CPT Code 61790 had a reimbursement
    value of approximately $4,800, while the typical reimbursement value for
    the RFS procedure performed at TPC was approximately $300 to $400. 
    Id. at 4-5,
    citing N.T., 4/23/2013, at 51, 54, 109.
    Next, the court cited to the evidence which “may have reasonably
    been interpreted by the jury as suggesting [Rogal’s] intimate knowledge of
    [TPC’s] billing practice as well as his control and complicity therein.” 
    Id. at 4.
    First, Rogal described himself as “the individual who ran the Pain Center.”
    
    Id., citing N.T.,
    4/23/2013, at 13.     When Dr. Kauffman confronted him in
    2005 with the letter he had received from an insurance company questioning
    the billing code, Rogal “neither expressed confusion nor directed the inquiry
    to [Kim Rogal].” 
    Id. at 4.
    Rather, the court explained:
    [Rogal] declared that the billing was being handled correctly,
    further explaining that insurance companies have been on a
    witch hunt, contesting his billing method for years.
    
    Id., citing N.T.,
    4/23/2013, at 103. Second, the trial court noted that when
    Dr. Palmerio confronted Kim Rogal with a similar letter, her “response
    - 12 -
    J-A06024-15
    mirrored that of [Rogal], assuring Dr. Palmerio that his concern was
    misplaced.” 
    Id. at 4,
    citing N.T., 4/23/2013, at 50. The court opined:
    Their shared retort when challenged about billing supported a
    reasonable inference that [Rogal and Kim Rogal] shared the
    conspiratorial intent to fraudulently bill rather than, as [Rogal]
    maintains, demonstrating that [Kim Rogal] was acting as a rogue
    employee.
    
    Id. at 4.
    Finally, the trial court noted “the expression of uncertainty by [Rogal’s]
    attorney regarding the propriety of [CPT C]ode 61790” who described the
    billing to Dr. Kauffman as “an ambiguous grey area.” 
    Id. at 5,
    citing N.T.,
    4/23/2013, at 115. The court opined the jury may have interpreted Rogal’s
    staunch support of the use of CPT Code 61790 in contrast to his attorney’s
    uncertainty “as corroborative of [Rogal’s] illicit intent.”   
    Id. at 5.
       Based
    upon the foregoing, the trial court found the evidence was sufficient to
    support a guilty verdict on the charges of corrupt organizations and
    conspiracy.
    Our review of the record supports the trial court’s decision. First, with
    regard to his corrupt organizations charge, Rogal argues there was no
    evidence he committed “even one predicate act of racketeering.”           Rogal’s
    Principal Brief at 12. Rather, he contends, the evidence demonstrated that
    Kim handled all the billing and developed the computerized billing system.
    However, the racketeering statute proclaims it unlawful to participate
    “directly or indirectly” in a pattern of racketeering activity. 18 Pa.C.S. §
    911(b)(3) (emphasis supplied).        Here, the Commonwealth presented
    - 13 -
    J-A06024-15
    evidence that indirectly linked Rogal to the racketeering activity.                          For
    example, Rogal characterized himself as “the gentleman who ran The Pain
    Center.” N.T., 4/23/2013, at 13. Moreover, based on his response to Dr.
    Kauffman’s concern regarding the billing, the jury could infer that Rogal was
    clearly aware of the billing issue, and, in particular, the insurance
    companies’ objections. See 
    id. at 103.
    It strains credulity to believe that
    Rogal, who was clearly the “doctor” in charge of the practice and director of
    the clinic, did not, at the very least, acquiesce to the improper billing
    practices    when    TPC        continued    to      bill    insurance     companies    at    a
    reimbursement rate ten times the value of the procedure even after being
    explicitly   instructed    to    stop   doing     so        by   the   insurance   companies.
    Furthermore, Rogal’s attempt to hide behind the advice of his attorney is
    similarly unavailing when two doctors in his practice both testified that a
    reimbursement value of $4,800 for the procedure they were performing was
    outrageous. See 
    id. at 73,
    109-110. Indeed, Rogal’s practice was receiving
    reimbursements ten times their value and billing for multiple procedures on
    a single patient when the Commonwealth’s expert neurosurgeon testified he
    would rarely perform the procedure at CPT Code 61790 even twice.
    Accordingly, we find the Commonwealth presented sufficient evidence for
    the jury to conclude that Rogal conspired with Kim to seek reimbursements
    for the RFS procedure at a much higher value than the procedure warranted,
    and therefore, either directly or indirectly, participated in a pattern of
    racketeering activities.
    - 14 -
    J-A06024-15
    With respect to his conspiracy conviction, Rogal contends the evidence
    established “nothing more than guilt by association.” Rogal’s Principal Brief
    at 16. Specifically, he argues the jury inferred his guilt based solely on his
    father/daughter relationship with Kim, when “[t]he established facts indicate
    that [Kim] acted alone when she took it upon herself to submit bills using
    CPT Code 61790, and took it upon herself to defend the use of Code 61790.”
    
    Id. at 21.
    Again, we agree with the trial court that “the jury was presented with
    evidence beyond merely the familial relationship to infer a conspiratorial
    agreement.”      Trial Court Opinion, 8/28/2014, at 5.    Rogal was the person
    who “ran” TPC. N.T., 4/23/2013, at 13. Although Kim handled the billing
    procedures, she was not a doctor. Therefore, it was reasonable for the jury
    to infer that Rogal was consulted regarding any medical questions about the
    billing.   Moreover, Rogal was clearly aware of the insurance company
    disputes, in which he defended the billing practice when confronted by Dr.
    Kauffman – characterizing the dispute as an insurance company “witch
    hunt”14 - and continued to approve billing under CPT Code 61790 after being
    instructed by the insurance companies to stop doing so.15 Accordingly, we
    find Rogal is entitled to no relief on his first issue.

    As 
    noted supra
    , Rogal’s attempt to place the blame on his attorneys is
    unavailing. He emphasizes the testimony of Drs. Kauffman and Palmerio who
    (Footnote Continued Next Page)
    - 15 -
    J-A06024-15
    Next,    Rogal     contends      the    trial   court   “abdicated   [its]   role   as
    gatekeeper” when it failed to provide the jury with contemporaneous
    instructions during the dual lay/expert testimony of Commonwealth witness,
    Dr. Dubeck.     Rogal’s Principal Brief at 23.           Rogal insists that Dr. Dubeck
    testified only as an employee of Blue Cross Excellus, and not as an expert
    witness, and the court should have instructed the jury as such. He argues
    the court’s failure to do so “guaranteed confusion on the part of the jury.”
    
    Id. at 24.
    Preliminarily, we note that “[a] trial court has broad discretion to
    determine whether evidence is admissible and a trial court’s ruling on an
    evidentiary issue will be reversed only if the court abused its discretion.”
    Commonwealth v. Huggins, 
    68 A.3d 962
    , 966, (Pa. Super. 2013) (citation
    omitted), appeal denied, 
    80 A.3d 775
    (Pa. 2013). Furthermore, this Court
    has held that a witness may testify as both a lay witness and expert witness
    during trial. As we opined in 
    Huggins, supra
    :
    _______________________
    (Footnote Continued)
    stated that both Rogal and Kim Rogal directed them to TPC’s attorney when
    they inquired about the billing practices. See Rogal’s Supplemental Brief at
    3-4. However, as the trial court noted in its opinion, Dr. Kauffman testified
    TPC’s attorney told him that CPT Code 61790 was “ambiguous” and the
    proper code was “a grey area.” N.T., 4/23/2013, at 115. Furthermore, Dr.
    Kauffman testified that after this conversation with TPC’s attorney, he left
    his position at TPC. 
    Id. at 103-104.
    Subsequently, he opened his own
    RFS practice, where his typical reimbursement is $300 to $400 per
    procedure. 
    Id. at 109.
    Therefore, the jury clearly could have determined
    Rogal’s feigned ignorance of the billing dispute was incredible.

    J-A06024-15
    [Pa.R.E.] 702 permits an expert to testify to scientific, technical
    or other specialized knowledge beyond that possessed by a
    layperson. [Pa.R.E.] 701 permits a layperson to testify in the
    form of an opinion, however, such testimony must be rationally
    based on that witness’ perceptions. Thus, an expert must have
    additional specialized knowledge in rendering an opinion;
    whereas, a lay witness must form an opinion based upon his or
    her rationally based perceptions. The Rules, however, do not
    specifically delineate that a witness must be only one or the
    other. Instead, the witness’ association to the evidence controls
    the scope of admissible evidence that he or she may offer.
    Furthermore, Pennsylvania Rule of Evidence 704 clearly permits
    both expert and lay opinion testimony on issues that ultimately
    must be decided by the trier of fact, in this case, the jury.
    
    Id. at 967.
    In the present case, contrary to Rogal’s assertion, Dr. Dubeck was
    accepted by the trial court as “an expert on medical billing.”              N.T.,
    4/22/2013, at 60. Rogal did not object to Dr. Dubeck’s qualifications as an
    expert witness, and therefore, he has waived any challenge to that ruling on
    appeal. See Pa.R.A.P. 302.
    With regard to Dr. Dubeck’s dual testimony as both a lay and expert
    witness, the trial court opined:
    Although Dr. Dubeck also offered non-expert testimony in the
    capacity of an insurance company employee, the court found
    that his dual testimony was easily distinguishable to the jury.
    [Rogal] specifically challenges an inquiry regarding a letter
    written by Dr. Dubeck to Kim Rogal condemning the use of code
    61790 as necessitating a contemporaneous instruction. The
    court found that the question, “did you in no uncertain terms in
    writing advise Kim Rogal not to bill your health insurance
    company using the code 61790 ever again?” was not an inquiry
    implicating technical expertise, but rather straightforward,
    comprehensible lay testimony. [Rogal] affirmatively endorsed
    the question as formulated, and did not maintain any objection
    to it. [N.T., 4/22/2013, at 174].
    - 17 -
    J-A06024-15
    [Rogal] also challenges as confusing Dr. Dubeck’s
    testimony regarding the appropriateness of code 61790 when
    only four of the five elements (of the code) are satisfied. 
    Id. at 102.
        In contrast to the above non-expert testimony, this
    particular inquiry seemed to clearly implicate Dr. Dubeck’s
    expertise. Specifically, his testimony that the Pain Center failed
    to accurately code the RFS treatment was based upon his
    citation to the procedure delineated in the coding instructions.
    Given that Dr. Dubeck’s expert assessment of the applicability of
    code 61790 was clearly articulated, the court did not find that
    the supplemental lay testimony elicited at trial presented an
    appreciable risk of jury confusion. Furthermore, the jury was
    instructed on the proper assessment of expert testimony as well
    as the evaluation of non-expert testimony. N.T. 5/1/2013 at 72-
    74, 102-103.
    Trial Court Opinion, 8/28/2014, at 6. We find the opinion of the trial court
    appropriately addresses the claim of Rogal on appeal. Accordingly, Rogal’s
    second claim is meritless.16
    In his last issue, Rogal argues he was denied due process of law
    because his attorney operated under a conflict of interest. Specifically, he
    contends that he and Kim were represented by attorneys who practiced in
    ____________________________________________
    16
    Rogal also argues that Dr. Dubeck’s testimony “is not reasonable or
    rational” because he “has a bad habit of using the pronoun ‘they’ without an
    antecedent noun.” Rogal’s Principal Brief, at 24-25. However, Rogal does
    not cite to any examples of this testimony in the trial transcript, and,
    significantly, does not state that he objected to this testimony at trial.
    Therefore, this claim is waived. See Commonwealth v. Thoeun Tha, 
    64 A.3d 704
    , 713 (Pa. Super. 2013) (“We have long held that [f]ailure to raise
    a contemporaneous objection to the evidence at trial waives that claim on
    appeal.”) (citation omitted); Commonwealth v. Harris, 
    979 A.2d 387
    , 393
    (Pa. Super. 2009) (“When an allegation is unsupported [by] any citation to
    the record, such that this Court is prevented from assessing this issue and
    determining whether error exists, the allegation is waived for purposes of
    appeal.”).
    - 18 -
    J-A06024-15
    the same law firm, and, although he waived the conflict of interest during
    the grand jury proceedings, his waiver did not extend to their joint jury trial.
    Further, Rogal argues that if his attorney had been conflict-free, the attorney
    “would have made an argument distancing [Rogal] from Kim Rogal.” Rogal’s
    Principal Brief at 34. Essentially, he claims his defense should have been to
    blame Kim for the fraudulent billing practices.
    When considering whether an attorney operated under a conflict of
    interest, we must bear in mind the following:
    [R]epresentation of co-defendants by different attorneys of the
    same law firm constitutes dual or joint representation.
    Commonwealth v. Albertson, 269 Pa.Super. 505, 
    410 A.2d 815
    (1979). … However, dual representation is insufficient to
    support a finding of conflict of interest, and is not a per se
    violation of constitutional guarantees of effective assistance of
    counsel. See Glasser v. United States, 
    315 U.S. 60
    , 
    62 S. Ct. 457
    , 
    86 L. Ed. 680
    (1942). To make the dual representation rise
    to a true conflict, appellant need not show that actual harm
    resulted, but must at least show the possibility of harm.
    Commonwealth v. Westbrook, [
    400 A.2d 160
    (1979)]. The
    law applicable to dual representation cases was delineated in
    Commonwealth v. Breaker, 
    456 Pa. 341
    , 344–45, 
    318 A.2d 354
    , 356 (1974):
    “Our dual representation cases make several principles
    clear. First, ‘[i]f, in the representation of more than one
    defendant, a conflict of interest arises, the mere existence
    of such conflict vitiates the proceedings, even though no
    actual harm results. The potentiality that such harm may
    result,     furnishes       the    appropriate     criterion.’
    Commonwealth ex rel. Whitling v. Russell, 
    406 Pa. 45
    ,
    48, 
    176 A.2d 641
    , 643 (1962). Second, a defendant must
    demonstrate that a conflict of interest actually existed at
    trial, because ‘dual representation alone does not amount
    to a conflict of interest.’ Commonwealth v. Wilson, 
    429 Pa. 458

    18 L. Ed. 2d 445
    (1967).         Third, ‘[t]o make the dual
    representation rise to a true conflict, appellant need not
    show that actual harm resulted, ... but he must at least
    show the possibility of harm ....’ Commonwealth v.
    
    Wilson, supra
    [429 Pa.] at 
    463, 240 A.2d at 501
    . Fourth,
    appellant will satisfy the requirement of demonstrating
    possible harm, if he can show, inter alia, ‘that he had a
    defense inconsistent with that advanced by the other
    client, or that counsel neglected his case in order to give
    the other client a more spirited defense.’

    Our review of the record, however, reveals Rogal was not subject to
    dual representation, and, even if he was, he waived any potential conflict of
    interest at the March 7, 2012, bypass hearing.
    It is undisputed that Rogal and Kim Rogal were both represented by
    Todd Henry, Esq., during the grand jury proceedings, and they both
    executed a conflict waiver during those proceedings.         After the criminal
    charges were filed, the Commonwealth petitioned the court for permission to
    file Bills of Information without a preliminary hearing.      Commonwealth’s
    Petition to File Bills of Information Without a Preliminary Hearing, 2/6/2012.
    A “bypass” hearing17 was held on February 16, 2012, at which time, the trial
    court granted the Commonwealth’s motion.           Neither Rogal nor Kim Rogal

    17
    A “bypass” hearing is conducted when the Commonwealth seeks to
    “bypass” the requirement of a preliminary hearing. See Rogal’s Principal
    Brief at 3-4.
    - 20 -
    J-A06024-15
    was present for the hearing, and a new attorney, who practiced in the same
    office as Mr. Henry, entered his appearance for Kim Rogal. 18 Accordingly, on
    March 7, 2012, the court conducted a second bypass hearing, with both
    defendants present, to address whether their attorneys were operating
    under a conflict of interest. See N.T., 3/7/2012, at 2-5.
    At the March 7th hearing, an associate of Mr. Henry appeared on behalf
    of Rogal, and Jeremy Walker, Esq. appeared on behalf of Kim Rogal. The
    prosecutor raised a concern regarding a possible conflict of interest because
    Mr. Walker practices in the same office suite as Mr. Henry, and his full
    biography is listed on Mr. Henry’s web site “as one of Mr. Henry’s
    associates.” 
    Id. at 8.
    However, Mr. Walker explained that while he serves
    as general counsel for Mr. Henry’s firm on civil cases, he maintains his own
    firm for his criminal practice:
    Basically, I have my own separate [practice] with regards to
    criminal law. I have my own firm, own LLC, own business 
    ID. The only
    thing I do with Mr. Henry is I’m his general counsel
    when it comes down to civil cases. Obviously, this is not a civil
    case. So that’s the only time we intermingle business is when it
    comes down to civil cases. As to criminal, we have two separate
    practices.
    
    Id. at 7.
    Accordingly, based upon Mr. Walker’s averment that his criminal
    practice is separate from Mr. Henry’s criminal practice, we do not find that
    ____________________________________________
    18
    Mr. Henry continued to represent Rogal.
    - 21 -
    J-A06024-15
    Rogal and Kim Rogal were subject to dual representation.        Nevertheless,
    even if the attorneys’ association did present a potential conflict in these
    circumstances, we conclude Rogal and Kim Rogal unequivocally and
    knowingly waived any conflict of interest.
    It is well established that:
    An individual may knowingly and intelligently waive a
    constitutional right. For that individual to be able to make a
    knowing and intelligent waiver of a constitutional right, he must
    have been aware of both the nature of the constitutional right
    and the risk of forfeiting the same. In such a situation the
    record must clearly demonstrate an intentional relinquishment of
    a known right or privilege. … Moreover, the Commonwealth
    merely needs to establish a knowing and intelligent waiver of a
    constitutional right by a preponderance of the evidence.
    Commonwealth v. Szekeresh, 
    515 A.2d 605
    , 607 (Pa. Super. 1986)
    (citations omitted), appeal denied, 
    529 A.2d 1080
    (Pa. 1987).
    In the present case, after Mr. Walker explained that he and Mr. Henry
    shared office space but maintained separate criminal practices, the trial
    court conducted the following colloquy:
    THE COURT: Okay. And Doctor Rogal, has [the shared offices of
    Mr. Henry and Mr. Walker] been explained to you?
    DOCTOR ROGAL: Yes.
    THE COURT: Ms. Rogal, has this been explained to you as well?
    MS. ROGAL: Yes.
    THE COURT: And you have independently retained, Doctor
    Rogal, Mr. Henry’s office?
    DOCTOR ROGAL: Yes.
    THE COURT: And, Ms. Rogal, you have independently retained
    Mr. Walker’s office?
    - 22 -
    J-A06024-15
    MS. ROGAL: Yes.
    THE COURT: Okay. And you both understand that they work
    together but they maintain separate practices?
    DOCTOR ROGAL: Yes.
    MS. ROGAL: Yes.
    THE COURT: Okay. And do you each understand that you may
    – or actually do have a conflict being defenses regarding the
    charges which have been brought against you?
    DOCTOR ROGAL: Yes.
    MS. ROGAL: Would you explain that?
    THE COURT: Yes. In other words, there has been charges
    brought against each of you, and there could potentially be
    different defenses which may apply to each of your cases.
    MS. ROGAL: Thank you. Yes.
    THE COURT: Okay. And have you considered that factor in
    terms of your retaining counsel to represent each of you?
    DOCTOR ROGAL: Yes.
    MS. ROGAL: Yes.
    THE COURT: Okay. And do you each understand what a conflict
    of interest is?
    DOCTOR ROGAL: Yes.
    MS. ROGAL: Yes.
    THE COURT: Okay. Has anyone forced you in any way into
    retaining the attorneys that you have retained?
    DOCTOR ROGAL: No.
    MS. ROGAL: No.
    THE COURT:      And you’ve each agreed to this arrangement; is
    that correct?
    DOCTOR ROGAL: Yes.
    MS. ROGAL: Yes.
    - 23 -
    J-A06024-15
    THE COURT: And do you understand that by agreeing presently
    that you are essentially waiving any future right to raise this
    issue regarding what may be perceived as a conflict of interest?
    DOCTOR ROGAL: Yes.
    MS. ROGAL: Yes.
    THE COURT:      And at this time, do either of you wish to
    reconsider your choice regarding the selection of counsel?
    MS. ROGAL: No.
    …
    DOCTOR ROGAL: No.
    THE COURT: Okay. Do you have any questions of the Court at
    this time?
    DOCTOR ROGAL: No.
    MS. ROGAL: No.
    …
    THE COURT: Okay. Then the Court, having colloquied Doctor
    Rogal and Ms. Rogal, is satisfied that they’ve made a knowing,
    intelligent, and voluntary selection of counsel. Okay.
    
    Id. at 8-11.
    Accordingly, contrary to Rogal’s contention, Rogal and Kim Rogal
    unequivocally and knowingly waived any potential conflict of interest after
    the criminal charges were held for court. See Rogal’s Principal Brief at 29.
    The court did not simply presume their waiver of a dual representation
    conflict during the grand jury proceedings was sufficient to waive any
    potential conflict for trial.19 Therefore, Rogal’s final claim fails.

    be represented by Mr. Walker who shares an office suite with Mr. Henry.
