The governing board of the Mississippi Department of Mental Health is composed of nine members appointed by the Governor of Mississippi and confirmed by the State Senate. Members' terms are staggered to ensure continuity of quality care and professional oversight of services. By statute, the nine-member board is composed of a physician, a psychiatrist, a clinical psychologist, a social worker with experience in the field of mental health, and one citizen representative from each of Mississippi's five congressional districts (as existed in 1974).

Meetings of the Board of Mental Health are open to the public. Meetings are held on the third Thursday of each month at 9:30 a.m. For more information, contact Grenaye Sullivan at 601-359-6260.
