Jamison Hedin, Recovery Coach
I am a recovery coach with Renaissance Ranch. I had a spiritual awakening while attending Renaissance Ranch myself in 2009 after a long battle with drugs and alcohol. I have found joy and fulfillment in seeing other men change through the practice and application of the 12-steps.  I have worked with those in early recovery in a professional and non-professional manner since 2010.  I have a significant amount of empathy for people who are in the early, intimidating stages of recovery and that is why I decided to work at Renaissance Ranch.  I take pride in what we do and enjoy seeing the light come on in the eyes of men who are fighting for their lives like I had to do early on, and just like I continue to do.

Claudeen CoxClaudeen Cox, Reccovery Coach Farmington

My name is Claudean, and I first became familiar with Renaissance Ranch when I enrolled in their program to get help with prescription drug addiction.  When I entered their program, I was consumed with guilt and shame because of my addiction. I felt completely unworthy of God’s help and love.  I was convinced I would never be able to get well and live a productive life.  From the very first day I was at the Ranch, I began to get well.  The staff taught me that I was not beyond help, and that God loved me no matter what.  I began to understand that addiction is a disease, and not a reflection of who I am as a person.  I began to see myself and my life from a totally different perspective.  I began to have hope in a brighter future.  I now work as a recovery coach in our Farmington branch, and I am happier and healthier than I have been in a very long time.  My goal as a Recovery Coach is to help bring hope and healing to those who choose to join us in their own personal quest to conquer alcoholism and addiction.  I am living proof that it is absolutely possible to live a happy, joyous and free life after drug and alcohol addiction. I am so grateful to my Heavenly Father for giving me the strength to get to where I am today.

Arielle JensonArielle Jensen, Recovery Coach Sandy Women
