Having helped thousands of individuals suffering with substance abuse and alcoholism, Mountainside is the foremost comprehensive, innovative addiction rehabilitation treatment center in the Northeast. Our mission is to elevate the standard in comprehensive drug and alcoholism addiction treatment in order to provide an unequaled rehabilitation experience for our clients.

Detox and Residential Programs

Our Detox and Residential programs ensure every individual gets a carefully designed addiction treatment plan tailored to your specific needs.

Removed from the stress, triggers, and temptations of everyday life, our serene campus at the foot of the Berkshire mountains serves as the perfect backdrop for you to fully engage in your recovery – mind, body, and spirit.
