HealthRIGHT 360's Walden House Residential Stepdown at Gateview is one of three transitional living facilities located on San Francisco's Treasure Island. This residential program provides supportive housing for individuals who are actively participating in outpatient treatment for substance use disorders, mental health conditions, or co-occurring disorders. Residents can attend either HealthRIGHT 360's own outpatient programs or external treatment services while maintaining stable housing at the Gateview location. The facility primarily serves vulnerable populations including those experiencing homelessness, justice-involved individuals, LGBTQ+ community members, young adults, people with histories of injection drug use, and individuals living with HIV/AIDS. While this particular program follows an abstinence-based approach, HealthRIGHT 360 offers alternative programs utilizing harm reduction models. The Gateview residential stepdown is part of HealthRIGHT 360's broader network of over 50 programs operating across 11 California counties, providing comprehensive care services tailored to diverse individual and family needs.
