Memorial Leadership
About the Board
The Memorial Health System Authority Board of Trustees, working in cooperation with hospital leadership and administration, sets policy and exercises ultimate authority over Memorial Health System of Southwest Oklahoma, McMahon Tomlinson Nursing Center and all entities associated with the Memorial Health System Authority.
The Board of Trustees is comprised of five community leaders appointed by Comanche County Commissioners on a voluntary basis. Despite countless hours of dedicated service to Memorial Health System of Southwest Oklahoma, the Board Members receive no form of compensation for their role as trustees, or hours of voluntary service.
The leadership of the Board of Trustees is determined through the annual nomination and election of officers. Members of the Board of Trustees nominate and elect members of the Board to serve in the capacity of Chairman, Vice Chairman and Secretary.
The Board of Trustees meets the third Tuesday of every month.
