Mark Willenbring, MD, DFAPA, is an internationally recognized addiction psychiatrist who has been pioneering new ways to treat alcohol and drug use disorders for over 30 years. Dr. Willenbring was featured in the HBO Addiction Special, has appeared on CNN, ABC, CBS, NBC, MSNBC national broadcasts, and has been quoted in the New York Times, Washington Post, Chicago Tribune, Los Angeles Times, Houston Chronicle, and the Minneapolis Star-Tribune. As Professor of Psychiatry at the University of Minnesota, his research focused on better ways to manage chronic complex conditions, where substance use, mental, and physical disorders are often combined. Within the VA Healthcare System, he was a leader in implementing research findings into clinical practice. Dr. Willenbring then moved to the National Institutes of Health, in Bethesda, MD, where he directed the Division responsible for funding research grants on alcohol treatment and recovery to Universities across the US. While there, he became aware that new knowledge and tools resulting from NIH funding of alcohol and drug treatment were not being made available to the people who needed them. The current addiction treatment system is not built on science, but on an antiquated rehab model that has not changed much since 1955. So when he left NIH to return to Minnesota, he was determined to stimulate transformative change in addiction treatment in America. Alltyr was formed in 2012 with that purpose, and the first Alltyr Clinic opened in St. Paul, MN, in 2013, to demonstrate a rehab alternative.
