Our Story
“When it comes to Public Mental Health in the State of California there are 58 counties, and then there is Tri-City.”
– Ontson Placide, Executive Director
Established in 1960 through a partnership between the cities of Claremont, La Verne, and Pomona, California, Tri-City Mental Health Authority, a government agency, delivers community-based behavioral health services that support healing, wellness, and recovery for residents of all ages and their families. Its unique structure, semi-independent from county mental health systems, allows the agency to stay closely connected to and responsive to the communities it serves.
