The Honorable John H. Sugiyama (Ret.) Joins JAMS in Walnut Creek

Former Contra Costa County Superior Court judge will serve as an arbitrator and mediator

New Panelist Announcement

Walnut Creek, Calif. – JAMS, the largest private provider of alternative and dispute resolution (ADR) services worldwide, is pleased to announce the addition of Hon. John H. Sugiyama (Ret.) to its panel. Judge Sugiyama presided for 18 years on the Contra Costa County Superior Court. During the last nine years of his judicial career, he served as the supervising judge for the probate division. Before his appointment as a judicial officer, he served as a senior assistant attorney general in both the criminal and civil divisions of the California Department of Justice and as a deputy director and chief counsel for the California Department of Corrections. 

Based in the Walnut Creek Resolution Center, Judge Sugiyama will serve as an arbitrator and mediator, handling disputes in the areas of civil rights, estates and trusts, and higher education.

Judge Sugiyama is highly respected and is known for being a compassionate, thoughtful and well-prepared jurist. We welcome him to the JAMS panel in Walnut Creek and wish him much success as he transitions into this new role.

- Chris Poole, JAMS President and CEO

 Between 2014 and 2019, Judge Sugiyama served as the chair of the Judicial Council of California’s Probate and Mental Health Advisory Committee. During his tenure, he helped inform the judicial branch’s position on all proposed state legislation in the field of probate law affecting the administration and operations of the courts.

I feel that my ability to understand different perspectives of litigants and to appreciate that those perspectives may change over time, will serve me well as a neutral with JAMS. I am looking forward to embarking on this endeavor and working with my fellow panelists at JAMS.

- Hon. John H. Sugiyama (Ret.), JAMS Neutral

Judge Sugiyama received his B.A. from the University of California, Berkeley and his J.D. from the University of California, Berkeley, School of Law.
