Golden Coast Rehab provides dual diagnosis treatment for adults at 8809 La Mesa Blvd., Suite 102, La Mesa, CA 91942 — our only facility, and the building every program on this site is delivered in.

Both lanes operate out of this one facility, so a client whose depression and drinking are tangled together is not driving to two providers on different days to have them treated separately.

Getting here

We are on La Mesa Boulevard, just off Interstate 8 near the State Route 125 junction, in the middle of San Diego County's East County. The MTS Orange Line trolley stops at La Mesa Boulevard, connecting west toward downtown San Diego and east to the Grossmont Transit Center and the Green Line. Full directions and parking detail are on our La Mesa location page.

What this program involves, who it suits, and what the schedule looks like are set out in full on our dual diagnosis treatment page. Nothing about the clinical content changes by location, because there is only one location.
