About me

Blending more than 35 years of experience in complex litigation, hundreds of hours of training in the “arts” of mediation and arbitration from premier national and international dispute resolution programs, and fourteen years as an acclaimed ADR professional, Greg Derin provides flexible mediation and arbitration processes to help disputants resolve even their most intractable problems. Greg’s unique background has earned him membership in elite professional organizations and recognition as a Power Mediator by The Hollywood Reporter and as an SuperLawyer™ in the fields of ADR, Intellectual Property Litigation and Entertainment and Sports.

During his career as a mediator, Greg has successfully assisted parties in resolving hundreds of complex matters. He is often called upon to resolve disputes after previous attempts at settlement have proven unavailing. Parties consistently attribute their successful resolutions to Greg’s persistence, attentive and open facilitation of a process designed to encourage creative solutions, and his broad substantive knowledge and experience. Greg has successfully helped parties resolve matters in a broad range of fields including contract, fraud, entertainment, intellectual property, real estate, employment, corporate and partnership, legal malpractice, class actions, and unfair business practices.


Greg is a Phi Beta Kappa graduate of the University of California at Berkeley, from which he received an A.B. degree with Highest Honors in 1976. Greg received a J.D. degree from Boalt Hall School of Law at the University of California at Berkeley in 1979, where he was on the editorial board of the California Law Review and was a Charles Mills Gayley Fellow.
