Medical Board of California Appoints New Executive Director

Published: Wednesday, March 3, 2020

(Sacramento, California) - The Medical Board of California (Board) has appointed William J. Prasifka as its new executive director. A native of California, Prasifka comes to the Board from the Medical Council of Ireland, where he has served as its chief executive officer (CEO) for the past four years. Prasifka will officially start his position with the Board in June.

"The Board has hired a very strong leader, someone who has been in a variety of government-regulation environments, including the regulation of physicians," Board president Denise Pines said. "I think that Mr. Prasifka will bring fresh eyes to the work that we have been doing and help us rethink the way that we are doing things."

Prior to leading the Medical Council of Ireland, which regulates the country's 23,000 physicians, Prasifka worked as the financial services ombudsman for Ireland's Financial Services Ombudsman Bureau, chief executive officer/chair of the Competition Authority (Ireland's statutory body responsible for the administration and implementation of competition law), and as a commissioner for the Commission for Aviation Regulation.

He is a 1984 graduate of the Columbia University School of Law, New York, and a 2018 graduate of the Harvard Kennedy School of Government, with 12 years' experience in leading law firms in both Ireland and the U.S.
