Ninth Circuit Mediators

The Ninth Circuit Mediation Office is led by Chief Circuit Mediator Stephen M. Liacouras and a team of seven Circuit Mediators who work exclusively for the U.S. Court of Appeals for the Ninth Circuit. The Circuit Mediators are all licensed attorneys who have an average of twenty-five years of combined government, private law and mediation practice. They are all experienced and highly trained in appellate mediation, negotiation, and Ninth Circuit practice and procedure. The Circuit Mediators are generalists and cases are assigned to them across all subject matters.
