Missouri Department of Mental Health

The Missouri Department of Mental Health was first established as a cabinet-level state agency by the Omnibus State Government Reorganization Act, effective July 1, 1974.

State law provides three principal missions for the department: (1) the prevention of mental disorders, developmental disabilities, substance abuse, and compulsive gambling; (2) the treatment, habilitation, and rehabilitation of Missourians who have those conditions; and (3) the improvement of public understanding and attitudes about mental disorders, developmental disabilities, substance abuse, and compulsive gambling.
