Certified Alcohol and Drug Counselor
Read Bio
I’ve been sober for 8 years now, working in treatment for 7 years. Throughout my years of working in treatment and also my own experience I’ve come to understand that recovery isn’t about the destination but it’s about meeting people where they are and supplying them with the tools and the information to overcome and heal in recovery. My goal is to provide a safe space where Clients are allowed to express themselves without the fear of being judged. A space where seeds can be planted, cultivated and nurtured in order to attain a specific outcome. I aim to provide the information, guidance and the correction that’s necessary to achieve the goal of lasting, meaningful sobriety.
