Green mountain treatment center is a transcendental environment full of amazing peopleWho genuinely care about the wellness and recovery of others. Amadeus Jackson and the alumni program help to reconnect me to so many recovered alcoholics and drug addicts which really expanded my fellowshipping abilities.

I was a frequent flyer at green mountain from 2020-2021. Although I had to go out and do a little more research they have me the tools I needed to eventually get my life together. I'm coming up on three years sober and life just keeps getting better.

This treatment center is not easy. My wife and I have both been here and jokingly refer to it as recover boot camp. You will be challenged to change… that being said it can save your life, IF you open your ears and mind, then do the work. I’ve been clean and sober for 3 years (and counting) mostly due to practicing the lessons from here. I made lasting connections from here that I still utilize.

I can not imagine my life without the GMTC experience. I do not believe I would have ever found recover without GMTC and it's people. I would definitely not be coming up on 6 years of absolutely serene and clean sobriety. Not only did my experience at GMTC save my life from alcoholism and drug addiction, but it taught me how to live my BEST life!I feel more like a real human being than ever in my entire life, even before my addictions took me away.PLEASE, if you are reading this, then you may have a problem, listen to me.You owe it to yourself and everyone around you to go to THIS treatment center.If you have never been to treatment (like me)...Go to THIS one.If you have been to 17 treatment centers... Go to THIS one!!!I did not believe recovery was possible...but I'm here to tell you it is AND it's at the Mountain.

Green Mountain saved my life. I was able to build a strong foundation there to start my recovery journey. Basic tools I didn't have beforehand to live one day at a time without a drink or a drug in my system. Without this place or the willingness I don't know where I would be today, almost 7 years after. Thank you GMTC 🙏🏻

Green Mountain Treatment Center has been an absolute game-changer in my journey to sobriety. Before arriving here, I was caught in the relentless grip of alcohol and drug addiction, feeling hopeless and unsure if I would ever regain control of my life.The compassionate and dedicated staff at Green Mountain provided me with personalized care and unwavering support throughout my recovery journey. They used a holistic approach that not only addressed the physical aspects of my addiction but also focused on the emotional and psychological roots. The serene and beautiful environment of the center allowed me to immerse myself in the healing process without external distractions.One of the most profound aspects of my experience was the strong sense of community at Green Mountain. I connected with others who were on similar paths, and we formed deep bonds of understanding and encouragement. These connections were invaluable and provided a network of support that made the recovery process feel less isolating.Thanks to the comprehensive treatment and 12-step program at Green Mountain, I now live a life free from the chains of alcohol and drug addiction. I am equipped with the tools and strategies to maintain my sobriety and face life's challenges with newfound strength and resilience. The journey hasn't been easy, but it has been incredibly rewarding.Green Mountain Treatment Center has given me a new opportunity to reclaim my life and live with a sense of freedom and purpose I never thought possible. I am eternally grateful to the incredible team at Green Mountain for their unwavering support and compassion. I wholeheartedly recommend Green Mountain Treatment Center to anyone seeking a transformative and life-changing experience.

Great facility! We got a struggling friend admitted quickly and he learned a lot about himself and his addiction. I highly recommend if you have a friend or family member struggling.

Canterbury Behavioral Health saved my life. I stayed here for four months: 6 weeks in residential, 5 weeks in PHP, and 6 weeks in IOP. I do not regret a single moment of it.All of the staff here are incredibly supportive and kind, even in the worst of moments. I certainly lost my cool more than a few times, but the staff was always there to pick me back up. They never once abandoned me or made me feel anything less than their number one priority.Danielle was one of the most supportive staff here, picking me up during my many panic attacks. She was always there for me and put me first even when she was overworked, exhausted, or extra busy. Alongside her was a wonderful team of equally-capable staff including Ava, Lisa, Kyleigh, Jimmy, Bob, Victoria, Emily, and Corinne. The tender care and support of all these people are a primary reason why I can call myself both sober and mentally stable once again. I couldn’t have graduated without such an amazing team. Chelsea, Jen, and Jenn were also wonderful supports, being in no small part responsible for building me up into the incredibly confident person that I graduated as.It is no exaggeration to say that this place saved my life. Even with the few blemishes and areas it could improve, this place should be the standard for mental health treatment nationwide. I cannot recommend this place enough.
