Our History


A History of Caring Service for the Northland

Tri-County Mental Health Services is now Beacon Mental Health.

Tri-County Mental Health Services began in 1990, to provide safety-net services to Clay, Platte and Ray Counties in Missouri in the areas of mental and behavioral health, and substance use disorders. In 2023, Tri-County Mental Health Services changed its name to Beacon Mental Health.

As the Northland region has grown, so has Beacon. To serve a diverse clientele in urban, suburban and rural settings, Beacon has developed a unique provider network allowing the agency to deliver convenient, cost-effective services to over 9,000 people each year.
