Johnson County Mental Health Center (JCMHC) began operation in 1962, providing outpatient services in one location. Today, a full array of mental health services are provided in five separate facilities located throughout the county. Johnson County Mental Health Center operates under the auspices of Johnson County Government and its operations are overseen by the Board of County Commissioners.
