What Mountainside does

Mountainside Treatment Center is a privately held, for-profit addiction treatment provider founded in 1998 and headquartered in Canaan, Connecticut. It delivers a full continuum of substance use disorder care — including 24/7 medical detox, residential treatment, partial hospitalization (PHP), intensive outpatient (IOP), outpatient services, medication-assisted treatment (MAT), recovery coaching, and continuing care — supplemented by specialty programs for adolescents, veterans, healthcare professionals, and individuals seeking bespoke (highly individualized) treatment plans. Family services and alumni programming extend the relationship beyond an acute episode. The organization operates six facilities across Connecticut (Canaan, Wilton), New York (Chappaqua, Huntington, NYC), and New Jersey (Ramsey), with a HIPAA-compliant virtual care platform extending the same clinical standard into additional states including Pennsylvania and Massachusetts.

The underlying technology is primarily a secure telehealth and care-coordination infrastructure rather than a software product. Virtual outpatient services, virtual withdrawal management, family therapy, and recovery coaching are delivered over HIPAA-compliant video, phone, text, and web chat, with no API, SDK, or AI/ML capabilities disclosed. Mountainside holds CARF Gold Seal, Joint Commission Gold Seal, ASAM 3.7 level-of-care certification, HIPAA, 42 CFR Part 2, and LegitScript approvals, and was designated a Recovery-Friendly Workplace by the State of Connecticut in 2022.

Mountainside's business model is insurance-based fee-for-service across all major commercial plans, with free insurance verification handled by dedicated intake specialists before treatment decisions. Go-to-market combines a 24/7 admissions-driven direct sales motion (800-500-0399, online inquiry, text, chat) with a formalized healthcare professional referral channel featuring a dedicated provider line and relations team. Revenue is generated from a long tail of individual patients and families rather than enterprise contracts; community and brand initiatives (Brighter Future Scholarship since 2021, Dopey Recovery Short Film Festival launched June 2026) support top-of-funnel awareness and reduce stigma around treatment entry. The company is led by CEO Andre Basso with no disclosed parent company, institutional investor, or private equity backing.
