• Available in Orange County, Los Angeles, All of California, Nationwide
  • Mediation Only


After 38 years as a litigator, Ed Oster moved out of the courtroom and became a full-time mediator. As a trial lawyer, Ed handled complex insurance coverage, bad faith, commercial and real estate litigation at the highest levels. He tried cases throughout all eleven major counties in Northern and Southern California, in both state and federal court. During that time he gained a lifetime of experience in all phases of civil litigation as well as an insider's knowledge of the insurance industry, all the while earning the trust and confidence of both co-counsel and adversaries who are now amongst his biggest supporters.

Ed passionately believes that the best settlements are those where everyone has achieved value, and that is what he delivers. His skill as a mediator springs from his natural ability to develop genuine relationships built on mutual respect. A top plaintiff's lawyer in Los Angeles says simply, "Extremely smart. Tough. Fair." A New York partner in a national defense firm observed: "He established almost instant rapport all around, and painlessly got the job done for all of us." A frequent mediation participant put it this way: "If you could go into a laboratory and put together in one person everything you want in a mediator - experience, integrity, intelligence, creativity and personality - you would have Ed Oster."

Case settled in one session.
