AMC provides a single, comprehensive source for mediation, arbitration, and other conflict resolution services.

The Arbitration and Mediation Center has been in operation since 1993. Co-founded by the present Director, Robert A. Murray, AMC was one of the first providers of alternative dispute resolution services in Sonoma County serving the North Bay Area. AMC was formed to meet the alternative dispute resolution needs of individuals, businesses and governmental agencies of Sonoma, Marin, Napa, Lake, Mendicino, Solano and Humboldt Counties.

Individuals and businesses frustrated over the high cost and time consuming nature of traditional litigation are increasingly turning to arbitration and mediation to resolve civil disputes. The Courts recognize that arbitration and mediation are often more appropriate forums for dispute resolution that the courtroom. We offer experienced, practicing attorneys as professional neutrals with a wide range of expertise in various legal matters. AMC panelists have successfully mediated cases involving a variety of subject matter, from personal injury, product liability, insurance, employment, and legal, medical malpractice actions to contract matters, construction, real estate, land use, business disputes, partnership dissolutions and probate.

Although they may not agree, the goal is for the parties to at least understand each other’s points of view and needs so they can move forward in a respectful and dignified manner and, with the assistance of the mediator and their respective attorneys, reach an acceptable and fair resolution."

"Creative strategies for settlement and resolution in a divorce are imperative for the parties who are forever bound together by their children. Even without issues involving children in the dispute, the parties can employ civility and come to a creative and mutually satisfying result by keeping an open mind and utilizing a trained and experienced mediator."

"The issues in family law usually have an emotional component that can magnify the intensity of the discussions. Mediation allows both parties the opportunity to fully address all of their interests and issues, and to create resolution options far beyond what might be relevant in a courtroom."
