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. As the Northland region has grown, so has Tri-County. To serve a diverse clientele in urban, suburban and rural settings, Tri-County has developed a unique provider network allowing the agency to deliver convenient, cost-effective services to over 8,000 people each year.
