Alameda County's trial court is the Superior Court of California, County of Alameda.[2] Its ADR Program can be reached at (510) 891-6055 or adrprogram@alameda.courts.ca.gov, and its lists of court mediators and judicial arbitrators sit on the court's Public Portal.[1] The court says mediation is voluntary and that all parties must agree to it, while it strongly encourages ADR before trial; ADR rules appear in its local rules.[1] The court's own panel could not be collected, so the mediators listed below come from other official panels, mainly the Santa Clara court database and the federal Northern District panel.[3][4]
Fact-checked Oct 7, 2026 against the official sources numbered above (listed under Sources). Court programs change; confirm with the clerk.
