About Us

Learn about the people and mission behind Advantage Treatment Centers.

Where it started…

Advantage Treatment Center Inc. (ATC) opened its doors in November of 1998 as a non-residential treatment center for court-ordered offenders in the Denver Metro Area. Our goal was to provide an array of treatment services to court-ordered individuals, from substance abuse to mental health treatment – including anger management and DUI treatments in Alamosa, Sterling, Montrose, and Lamar. We also offered monitored sobriety services. ATC’s primary focus was to provide quality treatment and supervision services while maintaining excellent communication and cooperation with our referring agencies, including Parole, Probation, and Courts, to ensure community safety at all times.

In 2005, we expanded our services to Northeast Colorado with the opening of a residential Community Corrections Facility in Sterling. We faced challenges in starting a community corrections program in a judicial district that had never had an adult community corrections facility before. However, we were determined to provide treatment modalities that either existed minimally or did not exist at all in the area. One of our successful services is the IRT program, which fills a need for the criminal justice system and the community in Northeast Colorado.

Our Approach & Values

Advantage Treatment Centers currently provides an array of treatment groups such as anger management, DUI classes, sex offender treatment, domestic violence treatment, relapse prevention, and advanced interactive journaling groups. We consistently practice evidence-based treatment modalities, disseminated and practiced in the State of Colorado. 

The mission of our addiction treatment centers in Colorado is to monitor and manage offenders in a residential and non-residential modality aligning them with treatment and vocational resources to best equip them for continued involvement in the community with positive, pro-social people and events.
