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.

Our Leadership

Doug Carrigan

Doug Carrigan

President & CEO

In the Spring of 2005, Doug Carrigan took a bold step that would indelibly reshape the landscape of community corrections in Colorado and beyond. Recognizing a glaring void in the provision of high-quality care and treatment for offenders in rural areas, he founded Advantage Treatment Centers (ATC) in Sterling, Colorado. Seventeen years later, his brainchild has burgeoned into a seven-site operation, setting the gold standard for offender rehabilitation and community reintegration.

Doug Carrigan is not just an entrepreneur; he is a visionary who saw beyond the limitations of existing systems. While many in the field of community corrections were focused on urban challenges, Doug discerned the unique service gaps that plagued rural areas. These were not merely logistical challenges but deeply rooted issues that required a nuanced understanding of the rural social fabric, local resources, and the specific needs of the justice-involved populations in these areas.

Committed to crafting a program that was both comprehensive and specialized, Doug ensured that ATC was designed to address the multifaceted challenges that present in rural settings. He was not content with merely filling a gap; he aimed to create an environment that provided offenders with high-caliber care and treatment. His vision was not just to manage offenders but to transform lives, fostering an atmosphere where individuals could not only serve their sentences but also acquire the skills and mindset needed for successful reintegration into society.

Under Doug’s astute leadership, ATC has achieved remarkable milestones. Today, the organization boasts over 108 Intensive Residential Treatment (IRT) beds, the highest concentration in the state of Colorado. But numbers only tell part of the story. ATC’s wide array of services, ranging from mental health support to vocational training, reflects Doug’s holistic approach to rehabilitation. He understands that effective treatment is not a one-size-fits-all proposition but a complex interplay of personalized care, community support, and evidence-based interventions.

Doug Carrigan’s impact extends beyond the walls of ATC. He has become a thought leader in the field, sharing his insights and methodologies through seminars, publications, and consultations. His work has not only elevated the standards of community corrections but has also ignited a broader conversation about the role of rehabilitation and treatment in the justice system.

Seventeen years on, Doug Carrigan remains as committed as ever to his pioneering vision. His relentless pursuit of excellence and innovation continues to drive ATC’s growth, solidifying its reputation as a beacon of hope and transformation for justice-involved individuals in rural communities.

In a field often fraught with challenges and skepticism, Doug Carrigan stands as a testament to what can be achieved through vision, commitment, and an unwavering belief in the transformative power of well-executed community corrections.
