SBELIH’s behavioral health services take a holistic approach to providing the highest caliber medicine, psychiatry and substance use treatment under one roof for an individualized inpatient and outpatient treatment experience for substance use and psychiatric conditions in Suffolk County.

Services include inpatient and outpatient Addiction Services under the Quannacut program and inpatient Psychiatry for Adults 18+. The philosophy of “Quannacut” (the Native American word for “hope’’ or “rainbow”) addresses addiction/chemical dependency as a treatable disease.
