Addiction Medicine Division

Gavin Bart, MD, PhD, FACP, DFASAM

Professor of Medicine, University of Minnesota Medical School
Faculty, Graduate Program, Department of Pharmacology, University of Minnesota Medical School

Combined, the use of tobacco, alcohol, and illicit drugs is the largest risk factor contributing to early disability and death on the planet. Medical and scientific advances are improving the lives of those with substance use disorders and can decrease the associated risks of drug use. As Director of the Division of Addiction Medicine, I am involved in the strategic oversite of our opioid treatment program, office-based addiction treatment clinic, hospital-based addiction consultation service, and the development of our faculty and trainees. My clinical focus is on treatment of opioid use disorder in an opioid treatment program setting and I also work in our office-based addiction treatment clinic. My research primarily focuses on the biological and pharmacokinetic factors that influence addiction treatment response and outcome. Through education and research I am engaged in helping health systems and communities implement best practices in addiction care.

I am committed to treating people with addictive disorders regardless of their background or circumstance. I specialize in pharmacotherapy for opioid and alcohol use disorders.

I also consult to the Hennepin Healthcare Interventional Pain Clinic and am a hospitalist on a cardiology teaching service. I am an Associate Program Director of the Internal Medicine Residency and am passionate about teaching at all levels. In addition to the work in the hospital, I have been involved in public health advocacy helping to pass various laws to protect people who use drugs, such as the naloxone and fentanyl test strip laws. I sit on state committees that set the standards for appropriate opioid prescribing and work with national organizations to educate clinicians about opioids. I have proudly treated patients at Hennepin Healthcare since 2002.
