Governing Board


To create seamless access to publicly funded mental health and substance use disorder services.


As of April 1, 2016, mental health and substance use disorder (SUD) services are integrated and operated by regionally operated Behavioral Health Organizations (BHOs) as managed-care entities. Thurston and Mason Counties became Thurston-Mason Behavioral Health Organization (TMBHO). The new Governing Board of the organization oversees and manages state-funded mental health and substance use disorder programs serving Thurston and Mason Counties.

TMBHO aims to reduce gaps in care and provide a more efficient and effective full continuum of services. A priority is to reduce the use of jails and hospital emergency departments for individuals needing ongoing behavioral health care including those impacted by homelessness. Currently TMBHO is working on building sufficient service provider capacity. The recent completion of the Crisis Triage facility will enhance the ability to divert those with chronic behavioral health disorders from incarceration into appropriate services.
