He has served as a volunteer Judge Pro Tem in the Superior and Municipal courts in Contra Costa County. He served on another eight of the County courts' arbitration and mediation panels.

Marc has taken over 340 hours of courses and seminars on ADR with various organizations, including the American Arbitration Association, the California State Bar and the American Bar Association. He also was a charter member of the Alameda County Bar Association Alternative Resolution Panel since 1995, and has served as a mediator, arbitrator, neutral evaluator and special master. Since 1983 he has heard--through court referrals from Contra Costa and Alameda Counties, as well as direct referrals, and through the ACBA program--an estimated 2250+ arbitrations and 2450+ mediations.
