About NYS OASAS Charles K Post ATC RRi

The Charles K. Post Addiction Treatment Center in Brentwood, New York, is a public, state-run facility that delivers a full range of support for adults 18 and older who are struggling with substance use disorders, including those with additional mental health challenges. The center operates a 51-bed inpatient rehabilitation program as well as a 42-bed community residence that serves as transitional housing. Clients receive treatment through individualized plans that may include medical services, one-on-one and group counseling, medication-assisted treatment, and targeted programming focused on topics such as cross-addiction, codependency, and strategies to prevent relapse.

A key aspect of the center’s approach is its emphasis on whole-person recovery. Services are designed to address physical well-being, mental health, emotional stability, and social functioning. In the community residence, participants are supported in developing skills for work and independent living through case management, vocational assistance, and linkage to local community resources. The center also offers specialized groups, including anger management and meditation, and it runs a separate women’s program that accounts for specific needs commonly encountered during recovery.
