IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA

SIXTH APPELLATE DISTRICT

POLYXENE G. KOKINOS, H052224 M.D., A.P.C., (Santa Clara County Super. Ct. No. 23CV418527) Plaintiff and Appellant,

v.

BRADLEY HILL,

Defendant and Respondent.

This appeal arises from a business dispute between a vascular surgeon and the clinic in Campbell at which he practiced. After departing the clinic at the end of 2019, Dr. Bradley Hill submitted a demand in arbitration pursuant to the terms of his practice agreement with Polyxene G. Kokinos, M.D., A.P.C. (Kokinos)—the professional corporation which owned and operated the clinic—asserting that Kokinos had failed to pay him his 50 percent share of net revenues for 2019. After Kokinos filed a counterclaim alleging that Dr. Hill had breached their practice agreement, an arbitrator awarded Dr. Hill $979,425.90 in May 2023. Kokinos filed a petition to vacate the award in June 2023, and Dr. Hill later filed a petition to confirm the award. The trial court denied Kokinos’s petition and granted Dr. Hill’s. Kokinos argues on appeal that it was deprived of due process in the arbitration proceedings, and that the arbitrator was biased against it. As a result, it contends, the trial court erred by not vacating the award pursuant to the grounds set forth in Code of Civil Procedure section 1286.2, subdivision (a).1 Finding no error, we affirm. I. FACTUAL AND PROCEDURAL BACKGROUND A. Surgery clinic and arbitration agreement Kokinos is a professional corporation doing business as the South Bay Vascular Center and Vein Institute in Campbell (SBVC). Dr. Polyxene G. Kokinos is a vascular surgeon and owner of SBVC.2 In 2019, Dr. Hill joined SBVC as a vascular surgeon, pursuant to the terms of a physician practice agreement he and Kokinos executed in November 2018 (the agreement). Among other things, the agreement included an arbitration clause which provided: “Any dispute or controversy arising between [Dr. Hill] and [Kokinos] (“Claims”) relating to the validity, enforcement, performance, or interpretation of this Agreement, including a dispute pertaining to the validity or enforceability of this provision (including claims by [Dr. Hill] against the Practice’s officers, directors, shareholders, partners, employees, or agents), as long as such Claims would otherwise be subject to a lawsuit in court, will be settled by binding arbitration under, and in accordance with, the then current National Rules for the Resolution of Employment Disputes (“Rules”) of the American Arbitration Association (“AAA”), to the extent such rules do not conflict with this Agreement. [Dr. Hill] and [Kokinos] understand that, by entering into this Agreement, they are waiving their rights to a jury trial in a court of law.”3 1 Subsequent undesignated statutory references are to the Code of Civil Procedure. 2 We refer to the appellant professional corporation as “Kokinos,” and to the vascular surgeon—who is not a party to this action—as “Dr. Kokinos.” 3 There is no evidence in the record that the agreement was presented to the trial court in its entirety. Instead, the record reflects that the agreement was presented to the arbitrator, but only select portions of it were provided to the trial court. Accordingly, as (continued)

2 The agreement also provided that Dr. Hill’s compensation would consist of 50 percent of the “net collected revenue from the combined operations of [SBVC] from [his] first day at the practice, anticipated to be January 3, 2019.” That did not include any revenue “collected by the practice for billings submitted prior to January 2019 and which may post in this same period.” The agreement specified that “net revenue” would be determined by subtracting qualified business expenses that were “required to continue the current function of the practice.” It also included a detailed, but non-exclusive, list of such qualifying expenses that would be subtracted from SBVC’s total revenue to determine the net revenue, which would then be divided equally between Dr. Kokinos and Dr. Hill. B. Dispute and arbitration demands Dr. Hill left SBVC after 2019. On January 20, 2020, he filed a demand in arbitration with the AAA, alleging that Kokinos had breached the agreement by failing to pay him 50 percent of the net revenue for 2019. Dr. Hill sought $999,999 in damages, in addition to unspecified amounts for attorney fees, arbitration costs, and interest. Kokinos asserted counterclaims, alleging that Dr. Hill had breached the agreement by failing to devote equivalent time and effort to the practice, failing to provide administrative services, not properly documenting and coding procedures he performed, and taking paid time off in excess of the amount provided for in the agreement. C. Arbitration stipulation Early in the arbitration process, the parties agreed to use a neutral forensic accounting expert (expert) to examine Kokinos’s books and records. The expert would calculate SBVC’s total revenue and all qualifying business expenses, subtracting the

we explain below, the entire agreement is not part of the record on appeal, notwithstanding Kokinos’s improper inclusion of it in its appellant’s appendix. Citations to the agreement in this opinion are limited to the portions of it which were presented to the trial court.

3 latter from the former to determine what, if anything, Kokinos owed Dr. Hill. The retention of the expert and the scope of her services were memorialized in a stipulation the parties executed on August 20, 2020 (stipulation). Among other things, the stipulation provided that the expert could request records from the parties, who were required to produce them within 20 days of the requests and to respond to any questions from the expert within 10 days. The expert would provide the parties a draft report on her findings, to which the parties could submit any objections or additional facts within 10 days. The expert would then consider the information from the parties and prepare her final report, which the parties could also challenge, although those challenges were to be limited to objections that had been made to the draft report. The stipulation also provided that Kokinos agreed to waive three of its counterclaims, preserving only its claim that Dr. Hill had taken paid time off in excess of the amount provided for in the agreement—a claim that could not be resolved by the expert. D. Forensic accounting investigation During the course of the expert’s accounting investigation, numerous disputes arose between the parties, resulting in nine discovery orders issued by the arbitrator.4 The expert ultimately issued her draft report on February 19, 2022. Pursuant to the terms of the stipulation, the parties submitted objections, additional information, and responses to the expert’s questions. One dispute in particular stemmed from the expert’s discovery of a check written by Dr. Kokinos on a separate bank account that Kokinos had failed to disclose to the expert, entitled “IVT – Kokinos, Polyxene” (the IVT account). The expert’s subsequent

4 There is no evidence in the record that the discovery orders—save one—were presented to the trial court. Therefore, those orders are not part of the record on appeal, notwithstanding Kokinos’s improper inclusion of them in its appellant’s appendix.

4 investigation found that Kokinos had deposited $311,167.78 of revenue into the IVT account for procedures performed in 2019. Kokinos utilized a software system called AdvancedMD for its billing and revenue management.
