Founded in 1979, HAART is a community focused not-for-profit collective of clinicians specializing in opioid replacement therapy, medical monitoring, counseling, and psychotherapy. 

We currently provide treatment for problematic opioid use (this includes heroin and prescription analgesics such as oxycontin / oxycodone, morphine, hydromophone, vicoden, fentanyl, and others), poly-drug use, co-occurring disorders, selective pain management, and after care. The two primary medications we utilize are methadone and suboxone.  We offer both maintenance and long term outpatient only detoxification slots  

Our clinicians also provide more comprehensive behavioral health care services via counseling, psychotherapy, and other peripheral care mediums. 

Our clinic is conveniently located on the San Leandro, Castro Valley and Hayward border and is easily accessible via car by 580 or 80 (via 238), by bus, and/or by BART train through either the Bay Fair or Hayward stations.
