What We Do

As CEO of ROSC Solutions Group Inc. (RSG), Dr. Carson McPherson is responsible for all strategic and operational aspects of the organization. He provides visionary leadership and oversees the design, implementation, and delivery of addiction treatment programs across Canada. Dr. McPherson's extensive experience includes managing a 75-bed residential addiction treatment centre as CEO for Cedars Cobble Hill, designing and implementing large-scale hospital-based programs, and operating supportive recovery houses in British Columbia.

​In addition to his role at RSG, Dr. McPherson is the lead author of the Recovery Communities Guidance Manual (2022), which serves as the framework for recovery community programs not only at Lakeview but across Alberta. His contributions to this manual reflect his dedication to advancing recovery-oriented systems of care and providing comprehensive support for individuals on their journey to wellness.

Dr. McPherson holds a doctorate in social sciences as well as master’s degrees in science and business administration.

Over the course of my career, I have had the honour and opportunity to work extensively in education, residential treatment, hospital and correctional facility settings, as well as medical-legal, occupational, and administrative roles.

Although my background is in family practice—I’m a University of Alberta MD graduate—as a person in recovery myself, for most of my career, my focus has been treatment for patients with addictions and assisting people in finding pathways to recovery.

In December 2022, alongside Dr. Carson McPherson, we formed ROSC Solutions Group (RSG) to support recovery-oriented care in Canada. After a competitive bid process, we were awarded several healthcare contracts by the Government of Alberta focused on supporting the province’s efforts to create a provincially based recovery-oriented system of care to address addiction and mental health challenges.

For a year and a half, I had the opportunity to be part of a team that established and is now operating therapeutic communities and ancillary services in four provincial jails through RSG’s subsidiary Beccarian Correctional Care. I found this work inspirational as I was able to witness people stepping into a pathway of recovery. 

Recently, I have stepped into a new position as RTIA’s Executive Director. It’s an exciting and transformative time. I see this role as more than just new responsibilities—it's a chance for personal growth, to inspire people, and to make a meaningful impact. I see this role as an opportunity to leverage my unique skills, creativity, and passion to drive real change and bring fresh perspect
