Stony Brook Medicine Quannacut Outpatient Services

University Hospital/Stony Brook ELIH provides outpatient addiction treatment at 905 East Main Street in Riverhead, serving the Suffolk County community through a program tied to the broader Stony Brook Medicine health system. For individuals who are past the acute phase of their recovery and focused on building sustainable sobriety, outpatient programming offers a structured treatment environment without requiring a leave from daily life.

The program's extended weekday evening hours — running until 9:00 PM on Mondays, Wednesdays, and Thursdays — and Saturday morning availability reflect a practical recognition that people in recovery have jobs, families, and obligations. That scheduling flexibility is a meaningful differentiator for adults and young people evaluating outpatient programs across Long Island.

Cognitive Behavioral Therapy forms the confirmed clinical backbone of treatment at Stony Brook ELIH. In substance abuse treatment, CBT equips people with concrete tools to recognize and interrupt the thinking patterns that sustain addictive behavior — skills they carry into their recovery community long after formal programming ends. This approach is well-suited to outpatient settings, where clients are applying what they learn in real time within their own environments.

The program treats co-occurring disorders and trauma/PTSD alongside substance use, addressing the full picture of what many people in recovery are managing. Dual diagnosis care at this level — offered within an accredited, academically affiliated outpatient program — means individuals do not have to choose between mental health treatment and substance abuse treatment or navigate two separate systems.

Stony Brook ELIH's outpatient program is designed to serve adolescents, young adults between the ages of 18 and 25, women, and individuals who are deaf or hard of hearing. The inclusion of deaf and hard-of-hearing individuals in the confirmed population list is notable — most addiction treatment and recovery programs do not make explicit accommodations for this community, which faces significant barriers to care in traditional settings.

This breadth of served populations, combined with payment options that span Medicaid, Medicare, private insurance, self-pay, and sliding-scale fees, signals a program oriented toward community-wide access rather than a narrow demographic. For families in Riverhead and across Suffolk County researching recovery centers that can serve younger or underserved community members, that accessibility is a concrete and relevant factor.

The program holds accreditation from the Joint Commission (JCAHO), one of the most recognized quality standards in healthcare. For individuals and families evaluating long-term recovery partners, accreditation matters because it signals that the program meets independently verified standards for care quality and organizational accountability — not just self-reported claims.

Financial accessibility is also built into the program's structure. Accepted payment includes Medicaid, Medicare, private insurance, self-pay, and a sliding-scale fee option. For people in early or ongoing recovery who may be navigating financial instability, a sliding-scale structure removes one of the most common barriers to consistent outpatient participation.
