Mountainside Chelsea

About Mountainside Chelsea

Mountainside Chelsea is the Manhattan outpatient center of Mountainside, a Northeast addiction treatment provider founded in 1998 that operates six locations across Connecticut, New York, and New Jersey. Their guiding belief is that recovery is possible for everyone, and they pair clinical therapy, medical oversight, and wellness practices to address the whole person, with many counselors and case managers drawing on their own recovery experience. In Chelsea, adults struggling with alcohol or drug use, including those with co-occurring mental health conditions, can attend an Intensive Outpatient Program or a standard Outpatient Program. Virtual options are also available, and the wider Mountainside network offers medical detox, residential treatment, and extended care for anyone who needs a higher level of support.

The 30-session IOP is geared toward early recovery, combining one-on-one work with a clinician and group sessions on topics like managing cravings, cross addiction, setting boundaries, and building a relapse prevention plan. The ten-week OP focuses on repairing relationships and building a sober network, and clients choose from weekly groups such as recovery maintenance using CBT, motivational interviewing, and solution-focused therapy; a women’s empowerment group grounded in CBT and DBT; CBT for co-occurring disorders; grief and loss work; and mindfulness-based integrative healing. Psychiatric evaluations, medication management, and toxicology screening help track how substance use has affected physical and mental health. Family members can join family therapy, a ten-week family recovery group, or one-on-one family recovery coaching, even if their loved one isn’t enrolled at Mountainside.
