Mountainside Chappaqua

Addiction recovery can involve many unexpected paths and at Mountainside Chappaqua, clients have rapid access to a full continuum of addiction treatment programs and services catering to the needs of adolescents and adults. A group of like-minded friends founded Mountainside in 1998. They believed that supplementing traditional therapies with holistic wellness practices could vastly improve long-term recovery.
Mountainside Chappaqua offers flexible morning and evening appointment services including medication-assisted detox (MAT), outpatient services, recovery coaching, and online counseling. Each client is unique, and they provide a full continuum of care that addresses the mind, body, and spirit. Their Integrative Model of Care guides clients sequentially through each stage of recovery, ensuring that each client’s treatment plan is specifically designed to cater to his or her individual needs. Mountainside provides a robust range of therapy options with qualified staff to find which therapies work best for the individual. Treatment can include individual and group counseling, 12-Step facilitation, anger management, acupuncture, adventure therapy, expressive therapy, healthy living workshops, therapeutic art and writing, and more. Mountainside believes the greatest asset for long-term recovery is a strong support system. They work closely with the client’s family and create support services to help loved ones understand addiction and the recovery process.
Mountainside has numerous facilities throughout the Northeast. The Chelsea, New York location is an easy commute for local residents within the New York City area. Mountainside is pleased to hold a 3.7 ASAM certification as well as dual accreditation from CARF International and The Joint Commission, making it 1 of just 7 addiction treatment facilities in the country to do so. Additionally, clients can self-pay.
