About Palm Avenue Social Model Detox A Program of Horizon Services Inc
Palm Avenue Social Model Detox is one of the dedicated detoxification programs of Horizon Services, a nonprofit recovery network that has provided substance use treatment across the Bay Area since 1976. Located at 2251 Palm Avenue in San Mateo, the program serves adults from San Mateo County and surrounding Bay Area communities seeking a safe, supervised place to withdraw from alcohol, opioids and other substances.
The social model of detoxification — distinct from medically managed inpatient detox — relies on a residential, peer-supported environment rather than a hospital setting. Trained staff monitor patients twenty-four hours a day, provide nutritional support, structured daily routines, group and individual counseling, and the consistent presence of recovery-oriented staff and peers. The model is appropriate for patients whose withdrawal does not require continuous medical management but who would benefit from a safe, sober environment with supervision and immediate access to medical referral if needed.
Horizon Services holds a three-year CARF accreditation across its programs, recognized by CARF for excellence in quality, safety, accountability and continuous improvement. Palm Avenue inherits that accreditation and operates under Horizon’s mission to cultivate or restore hope, self-awareness and community to people impacted by substance use and mental health challenges. The organization explicitly orients its services toward trauma-informed care, treating patients regardless of race, gender, class or sexual orientation.
The program serves adult Medi-Cal beneficiaries — an important access point in San Mateo County’s safety-net behavioral-health system. Bilingual English-Spanish services support the region’s significant Spanish-speaking population. Patients can reach Palm Avenue at (650) 513-6500, and Horizon’s broader Bay Area network spans Alameda, Santa Clara and San Mateo counties, allowing for warm hand-offs to residential, outpatient or sobering programs as patients move through the continuum of care.
