Board of Trustees

The WMS Board of Trustees is composed of executive officers and up to 16 county component society seats, who provide statewide representation. Retired physicians, Physician Assistants, Residents, and Students are also represented on the WMS Board. These individuals participate in determining policy, responding to developing situations, and receiving and acting upon reports from committees and task forces.
