This place takes recovery very seriously, after sitting thru classes I can say it care equally about the new comers or some like me, one that’s been thru the steps and had a lot of sober time and just needs a tune up. I would give this place an AAA+++.

 Trustindex verifies that the original source of the review is Google. Walking through the doors of Oasis Treatment Center was truly the beginning of a brand new chapter in my life. I can honestly say this place has changed everything for the better. Thanks to the amazing staff, the compassionate support, and the solid foundation I built in sobriety here, I am now reunited with my family and pursuing my dream of becoming a business owner—something I never thought would be possible before. I want to give a huge shout out to Courtney Chipman, who was incredibly helpful and kind during my admission process. She made everything feel less overwhelming and gave me hope from the very start. Courtney, you were the first light at the end of the tunnel, and I’m forever grateful. Today, I am sober, hopeful, and thriving. I’ve found purpose, confidence, and a deep appreciation for the life I’ve been given. I feel beyond blessed to have found Oasis. This place didn’t just help me get clean—it helped me rediscover who I am and what I’m capable of. My future looks bright, and I’ll always have Oasis to thank for giving me the tools, strength, and support to live the life I was meant to live

Life in Recovery – Beyond the Therapy Room

Healing at Oasis Treatment Centers isn’t limited to counseling sessions and clinical support. Every Friday, clients participate in community-based outings and activities such as paddleboarding, hiking, bowling, disc golf, and beach days. These shared experiences help clients rediscover joy, build confidence, and strengthen bonds with peers in recovery.

Occasionally, staff and clients come together for larger outings, like attending professional baseball or hockey games — reinforcing that recovery also means reconnecting with life, fun, and community.
