Reviews & Testimonials

quote testimonial

My daughter’s time at Mountainside gave her the foundation to heal.

I remember the day I found out my daughter was addicted to heroin and desperately needed help. I will always be grateful to her therapist who suggested I reach out to Mountainside. While I was extremely nervous as I opened the doors to the facility, I immediately felt a sense of calm from each individual who walked us through the process. My daughter’s time at Mountainside gave her the foundation that really started her healing process. I am very proud of my daughter and grateful that Mountainside empowered her to find a happier life.

Lifelong learning

My life has improved because of the steps, meditation, and yoga, but the number one reason why my life has improved is because I learned to love myself at Mountainside.

“Incredible sober network” for life beyond recovery

The staff was a really big part of my recovery, allowing and providing a safe and honest environment. I developed a great network of friends and an incredible sober network that I wouldn’t have had, had it not been for this awesome place.

I always feel heard at Mountainside

Mountainside gave me a safe place to lay my head, and heal my trauma with the help of world-class clinicians. I love the Alumni department because it offers exclusive access to a recovery community and five-star events. No expense is ever spared with Mountainside. I always feel heard at Mountainside, where I know I make a difference because I know the difference Mountainside helped me to make in myself.

Compassionate, caring staff

This is a first rate facility with compassionate, caring staff that know what they’re doing. Having our son in recovery has been a blessing (and an emotional roller-coaster ride) and Mountainside has been there every step of the way.

I’ve been clean since I left

Like many addicts I wanted to leave after two days. But the nurses and the therapists did everything they could to convince me to stay. I was there in April of 2018 and I’ve been clean since I left.

A hub for recovery in NYC

I had an amazing experience at Mountainside Chelsea! The space is absolutely beautiful. There is a game room with ping pong, pool, vending machines, and much more. I went to an event at Mountainside and had a blast. The staff was warm and welcoming and made me feel right at home. The food was also delicious. I will definitely be coming back here for another great time!

Second to none

I have had the opportunity to work with Mountainside and their entire team for some years now. As they grow and expand their services in new areas the new Recovery HUB in Chelsea may be the most exciting site yet. The mission and atmosphere created there is second to none. The space is beautiful and welcoming creating a safe place for those in NYC to have sober fun. Well done again, Mountainside team!

A holistic approach to recovery

Mountainside has played a major role in my successful road to recovery. I tried a year before at a different recovery center and relapsed. They are the welcoming front door that seems impossible to pass through on your own. The difference between the first center I went to and Mountainside is that they concentrated on AA and 12 Steps and Mountainside concentrates on mind, body and spirit in addition to AA and the 12 Steps.

Incredible work

Thank YOU! I am so grateful for this opportunity to learn with you. The Mountainside Virtual CE workshop I attended was a tremendously informative and well-orchestrated event. Enjoyed indeed! I am one semester away from graduating with my MSW (clinical track).

I signed up for your webinar because I am taking a substance use class as one of my “final four.” I did not have any IPNB knowledge/thorough addiction as brain disease knowledge until today. Without a doubt, thanks to you, I feel better prepared tackle the class work. I hope that there will be more opportunities to learn like this with you and your team…this made me very joyful and hopeful that I am on the right path in my career choice!
