Board of Directors
Governing this private, nonprofit medical center is a group of volunteer board of directors.
The board appoints its own members from the GRMC service area. Their primary functions are to
- establish the mission and vision;
- strategically plan for the future;
- appoint members of the medical staff;
- approve the annual budget and provide financial oversight;
- monitor overall quality of services; and
- appoint the chief executive.
The directors, also called trustees, represent communities as well as business and industry and community groups. Much of GRMC’s success may be attributed to the trustee’s diversity: in occupations, ages, perspectives, and places of residence.
