Testimonials
  • When I came to Willow Tree my life was totally out of control. I was a broken person. In the course of a few short months I had lost everything; my dignity, self-respect, self-confidence and most of all the respect of my family. To say that Willow Tree changed my life would be a huge understatement. I came here with nothing and left with everything I had lost and more. Willow Tree literally saved my life and gave me the knowledge and skills necessary to master my disease and move forward with sobriety.

    —Stephanie

  • My experience at Willow Tree was fantastic. My counselor was very sensitive, empathetic and genuinely involved in my recovery. The ropes course, Yoga, and nature therapy were great. Willow Tree has given me the perfect amount of comfort & discomfort to grow as a functioning person with a strong foundation in recovery.

    —Carissa

  • When I entered Willow Tree I was confused, afraid and full of anxiety. Within several hours I felt at home. The facility is warm, comfortable and friendly. Within a week or ten days I felt my life was becoming manageable again. The emphasis on diet and exercise helped me regain my physical strength and the group and individual therapy sessions were so meaningful in helping me understand who I am and how to be successful in society without the need for drugs or alcohol.

    —Travis

  • For the first time in a long time I am sober. I was at a point in my life where I never imagined it possible to have several continuous months of sobriety. I have been able to start the healing process with my family and we are making progress. I can have an intelligent conversation and remember what was discussed. I have come to understand the disease of addiction and the need to embrace recovery one day at a time. I am so thankful circumstances brought me to Willow Tree. Every aspect of my individual treatment plan fit my needs exactly. My sincere thanks to everyone who helped me find my way back to a life I had lost and never thought I could regain again.

    —Curtis
