 Ottis Johnson, CADC- CAS

Family Recovery Specialist

I have been working in the field of recovery for over thirty-eight years. I have personally been clean and sober for over forty years which gives me some unique insights into helping people transition from addiction into long term recovery. The one thing that I have become acutely aware of is that addiction is not an individual disease but rather a family disease.   Helping the addict seeing him or her self as being part of family that needs to be healed and what part they play in the healing process. Involving the entire family in the recovery process offers the best possible outcomes.  I have successfully created the Otis Loves You Family Recovery Program, workshops and groups that create on-going support systems for the recovering addicts and their families.

Brian Zanella


My name is Chef Brian Zanella. I have over 20 years experience working in kitchens all around Orange county. My journey started when I was hired as a busboy in 1998. I fell in love with the food scene and decided soon after that I wanted to become a Chef. I put in my time working for as many different Chefs as I could and eventually acquired the title of Chef in 2013.

In 2015, my substance abuse problem had caught up with me and I knew that I needed to get professional help. After checking into treatment, I decided to take some time off away from the kitchen. 2 1/2 years into sobriety, I was fortunate enough to get back into the kitchen with a clear mind. This time my focus would be on giving back the gift of nutrition for people who are struggling as I once did. Today, my life is full of gratitude and compassion for anyone struggling with substance abuse. Tres Vistas Recovery has afforded me a amazing opportunity to combine my passion for cooking while helping patients get the best nutrition possible during their stay.
