San Mateo County has an active Behavioral Health Commission (BHC). From its founding in 1958 until October 2010, the Commission was called the Mental Health Board, then the Mental Health & Substance Abuse Recovery Commission until May 17, 2022.  The Commission recognizes that mental illness and substance abuse are often co-occurring and interrelated, and supports the merger of Mental Health Services and Alcohol and Other Drug Services into the Division of Behavioral Health & Recovery Services.
