Michael M Wagner | Certified Addiction Specialist

After a successful career in the Investment Business, I retired at 58 and moved to Colorado. Thanks to the encouragement of my wife of now 53 years, I began volunteering at CeDAR, The University of Colorado Hospital’s nationally recognized Center for Dependency, Addiction and Rehabilitation.

During my four years there I began work to earn a Certified Addiction Specialist certificate. I facilitated weekly groups at CeDAR, and served as a Sponsor to selected clients under the supervision of John Hardman, MD, LAC. I celebrated my 43rd year of sobriety in August of 2023.

Through these four decades and my 10 + years of experience with CeDAR and Valiant Living, I have gained a deep insight into the challenges we addicts face day to day as we begin to establish some equilibrium in our lives, and gain the strength and humility to acknowledge our vulnerability and focus all our resources on getting well.

Perhaps more importantly I have experienced the rewards that follow a diligent program of recovery.

I love working with my fellow addicts. We are brothers. This journey turns out to be a profound gift for which I am very grateful. It is a privilege sharing my experience and all that I am learning with my peers.

Thank You Valiant for having me work with your extraordinary clients in your PHP, IOP and Detox programs
