US Board of Directors

Members of our association elect the Board of Directors to govern Doctors Without Borders/Médecins Sans Frontières USA (MSF-USA) on our behalf. 

Members then hold the Board accountable for its actions. Board members elect the Executive Director, take responsibility for the actions of MSF-USA, and work to guarantee that the MSF principles are respected.

The Board sets broad strategic directions and delegates the implementation of strategy to the management team, who run the office day-to-day. Every month the Board meets to ensure that MSF-USA continues to operate well and is achieving its objectives.
