A History of Caring Service for the Northland

In 1990, Tri-County Mental Health Services opened its doors, introducing an innovative health care model to the community.

The agency is the primary provider of comprehensive behavioral health services to a community of nearly 400,000 people who live north of the river in Clay, Platte and Ray counties. These counties include urban, rural and suburban areas.

Tri-County developed a unique provider network allowing the agency to deliver convenient, cost-effective services to nearly 9,000 people each year. In addition to hiring agency-based staff to provide services to the community, Tri-County out-sources clinical treatment for behavioral health problems to professionals who live and work throughout the three-county area. Tri-County has a site-based staff of less than 100, but a network of dozens of individual and agency providers and more than hundreds of volunteers.

Tri-County's strong emphasis on prevention, assessment, education and clinical services has earned the agency a regional and national reputation as a foremost provider of effective behavioral health solutions. The agency is accredited by The Council on Accreditation of Rehabilitation Facilities (CARF) and has been recognized for the quality of our services.
