This place truly helped save my life and I couldn’t be more grateful!!! The staff are amazing and have so much to offer. Between their experiences, strength and hope combined with a passion for what they do this absolute power team will give you all of the tools and resources you need to combat mental health and addiction. The whole case management team is right there to help you with whatever you need and they always encourage you to come find them at any time . They’ll help to set up appointment get In touch with attorneys and things you might not even realize you need. I was parred with a lovely young lady named Corinne and she’s absolutely amazing it’s truly a blessing to have had such a dedicated person on my team to help me every step of the way. Also from the bottom of my heart want to thank 1 particular group facilitator she was my rock through and through and I consider the more than just a friend and she goes by MJ. To anyone seeking recovery please do not hesitate to call. You are loved ,you are worth it, and most of all you’ll never feel alone at Gatehouse.
Gatehouse Treatment center has forever changed my life. I’ve been struggling with my addiction for a little bit and when i came to gatehouse the staff welcomed me with open arms. I cannot say enough about the staff. Kind, caring, understanding, empathetic, you name it. I love every staff member but there is a few that have truly listened to me and tried so hard to help me through the tough times. Sheila and Russell have seen me go through hell more than once and have always been extremely helpful. I first met Sheila as a BHT and she was always there for me when i needed to vent. Russell was always there to make me laugh when i feeling low. I couldn’t be more appreciative. If you need to help with your addiction Gatehouse is truly an amazing place to get help.
I’ve had a great experience at gatehouse. The staff as a whole went above and beyond for anything I needed no matter what it was I knew I was covered. Gatehouse is going to be a huge part of the reason I will stay sober from here on out. Love all the staff and the program!
Marcus is the best case manager I have ever had. And he truly cares about his people. I have nothing negative at all to say about the treatment center and the folks that work there. Thank you soo much for all you guys did for me. MARCUS is the best
On my very first day at Gatehouse I was very uncomfortable if the unknown and in fear of change. I sat in the back of the class and didn't say a word until I didn't anymore. It was because of John Mylly and the rest of the staff that I came out of my shell and became a better person. I spoke in groups and I am still sober today because óf Gatehouse. Still to this day I continue to grow and be in the journey that I am in because my case manager John Mylly still picks up the phone for me and to help me. Whatever I need if he can he helps. I'm so very Grateful for the giving hearts at this program. I would highly recommend Gatehouse to anyone. I still stop in to say hi to everyone but mainly to see John he is an amazing man and he's more than willing to help anyone if he can. Thank you to all the staff at Gatehouse for the help I needed to get me where I am today.
