South Oaks Hospital

What South Oaks Hospital does

South Oaks Hospital is a 202-bed psychiatric and addiction treatment facility located at 400 Sunrise Highway in Amityville, New York, on the border of Nassau and Suffolk counties. Founded in 1881 as The Long Island Home Hotel for Nervous Invalids and rebranded South Oaks Hospital in the 1950s, it operates today as a wholly-owned subsidiary of Northwell Health, a 501(c)(3) nonprofit health system that operates 21 hospitals and 455 state-licensed psychiatric beds across New York. The facility has provided behavioral health care for more than a century and offers a full continuum of services including age-segregated inpatient psychiatric units for children, adolescents, adults, and seniors; a partial hospitalization program for adolescents; the Comprehensive Outpatient Behavioral Services (COBS) program for youth ages 5–21; inpatient detoxification and rehabilitation plus outpatient substance use disorder clinics; a college partnership program with a dedicated inpatient unit; school-based mental health services under annual contracts with 50+ Long Island school districts; the OnTrackNY early psychosis intervention program; and a Career and Educational Counseling Center providing vocational rehabilitation for adolescents and young adults with disabilities.

The hospital's clinical model is built on evidence-based treatment modalities — dialectical behavior therapy (DBT), cognitive behavioral therapy (CBT), trauma-informed care including the Seeking Safety protocol, and medication-assisted treatment for substance use disorders. A notable proprietary asset is the South Oaks Gambling Screening (SOGS) tool, developed in-house in the 1980s and now distributed free of charge to healthcare institutions worldwide in multiple languages. South Oaks derives revenue from insurance reimbursement (including Medicaid and Medicare), state-funded mental health initiatives, and contracted annual service agreements with K–12 school districts and college partners for psychiatric consultation. The institution holds the ANCC Pathway to Excellence designation and is integrated into Northwell's broader behavioral health network, with co-located outpatient clinics in Amityville and Riverhead. Recent strategic activity (2025–2026) includes a second dedicated college inpatient unit, new outpatient facilities in Riverhead and Melville, and $6.6 million in New York State grant funding earmarked for additional psychiatric beds at the Amityville campus.
