About Quest Recovery Center

At Quest Recovery Center, our mission is simple - to provide premier evidence-based care for each of our clients and change the narrative on stigma associated with substance use disorder. Addiction is personal, and very difficult to overcome without the right tools and support structure to help enable a successful outcome. Our practice commits to being your partner in the recovery journey and helping you achieve freedom from the debilitating effects of chemical dependency.
