Dennis Fox
RADT, Operations Manager

Dennis Fox
I began my career as a professional musician at a young age. I lived and breathed for nothing more than music, until, of course, I found a new obsession. Little did I know at the time that chasing that feeling would lead me down the darkest of roads, through a tunnel that has no light at its end. Although there was nothing to look forward to in the life that I was living, it turned out that there was a different way to live. I was shown a new path, for which I am eternally grateful. Today, I get to show that gratitude by sharing that path with others. My job is to ensure that you receive the highest quality of care in the best possible environment, and I thoroughly enjoy my job.

Marcus Davis
RADT, Counselor/Case Manager

Marcus Davis
Hello, my name is Marcus Davis. I work at Invigorate Behavioral Health as a Counselor/Case Manager. I struggled with addiction for 15 years. Beginning in my early teens, I began using drugs and alcohol recreationally, and it escalated very quickly to daily use. During my addiction, I have lost jobs, ruined relationships, and lost my sense of self. After multiple lengthy hospitalizations as a result of my addiction, I finally got to the point where I realized that I couldn’t manage my addiction on my own and needed help. That was the turning point. I was tired, broken, and afraid when I reached out for help and decided to go to treatment. I entered treatment not knowing what to expect and not thinking it would work. I stayed in treatment for 9 months, and thanks to the staff at that treatment center and the community of people from 12-step meetings, I have been able to slowly rebuild my life. Today, I live clean and sober, which is something that never seemed possible for me. I love what I do today and have a passion for helping others navigate the path of sobriety. The past and mistakes I made in my addiction don’t define me, but it does help fuel my passion to guide others toward healing and freedom.
