Samuel S. Siavoshi is an associate attorney in the Workers’ Compensation department at Mastagni Holstedt, APC.  He represents southern California clients in hearings and trials before various Workers’ Compensation Appeals Boards throughout the region.  Samuel’s unique real-world experiences include serving as an attorney in the United States Air Force, working as a litigation attorney, and operating abroad in multiple countries.

During his time with the Air Force, he represented the government in a broad range of aviation, medical, criminal and civil legal issues. He was the Junior Attorney of the Year for two consecutive years at the Space and Missiles Center in Los Angeles. His efforts supported a multi-billion-dollar contract portfolio that included the development and sustainment of the Global Positioning System satellite. “Serving my country instilled leadership and other valuable interpersonal skills.  I can think of no better preparation for the work we’re doing at Mastagni Holstedt, APC on behalf of our clients.”

After his time with the Air Force, Samuel went on to work at two reputable law firms in Irvine, California where he practiced in the areas of business and civil litigation. While there, Mr. Siavoshi utilized his background of excellence working on matters involving shareholder disputes, contract disputes, partnership disputes, fraud actions, receiverships, municipal law, and real estate disputes.
