What Serenity Knolls Treatment Center does

Serenity Knolls Treatment Center is a private, for-profit residential addiction treatment facility located on a single 145 Tamal Rd campus in Forest Knolls, Marin County, California, operating for more than 25 years and serving adults aged 18 and older with substance use and co-occurring mental health disorders. The center delivers an evidence-based treatment program that combines 12-step principles with individual, group, experiential, and family therapy, structured into five integrated service modules: Detox, Residential Treatment, the Extended Care Foundation Enrichment Program, the Weekend Family Program, and a free lifetime Aftercare Program (weekly meetings in Marin County and San Francisco for alumni who complete at least 30 days of treatment). A distinctive operational feature is that 85% of staff are in personal recovery themselves, supplemented by a multidisciplinary clinical team of psychologists, marriage and family therapists, and certified addiction counselors; the facility is CARF-accredited, licensed by the California Department of Health Care Services (Program ID 210011AP, expiring 4/30/2028), HIPAA-compliant, and was included in Newsweek's 2025 list of Best Addiction Treatment Centers in California.

The business operates as a subsidiary of Acadia Healthcare Company, Inc. (NASDAQ: ACHC). Revenue is generated from insurance reimbursement (Aetna, Anthem Blue Cross Blue Shield, Kaiser Permanente, Optum, TriWest Healthcare Alliance) and private pay; Medi-Cal is not accepted. Go-to-market is direct and sales-led: same-day admissions via phone (833-308-2555) and website, free insurance verification, and a professional referral channel targeting community physicians, therapists, and interventionists, with ongoing communication maintained with referring providers during a resident's stay. Marketing is concentrated on the company's website (including five free online self-assessments), organic SEO, and a modest social/employer-branding presence on Facebook, LinkedIn, Indeed, and Glassdoor; there are no public APIs, no disclosed AI/ML capabilities, and the technology footprint is limited to Google Analytics and a Surescripts HIE integration for medication history.
