The Guam Department of Mental Health and Substance Abuse (DMHSA, Chamorro: Dipattamenton Salut Hinasso Yan Abuson Amot) is a government agency of Guam. The agency's main facility is located in Tamuning, across from Guam Memorial Hospital.[1][2]
Guam Senator M.K. Hartsock introduced a bill that would create the DMHSA. Hartsock's bill became public law 17-21, and the DMHSA was established on August 19, 1983. Prior to that date, the Guam Memorial Hospital provided mental health services.[1]
