Before joining Dell Medical School, Mueller was a professor of medicine and biomedical ethics at Mayo Clinic College of Medicine and Science. From 2009 to 2018, he was chair of the Division of General Internal Medicine at Mayo Clinic in Rochester, Minnesota. From 2018 to 2024, he was regional vice president of Mayo Clinic Health System in Southwest Wisconsin, overseeing two hospitals and eight clinics, during which the “hub” hospital in La Crosse achieved the highest patient experience, quality, and safety rankings including CMS’s 5-star and Leapfrog’s grade A rankings. He also proposed and carried out a plan to replace the antiquated Saint Francis Hospital with a new $250 million hospital, which opened last year. During his 29 years at Mayo, he served in many leadership roles, including chair of the Mayo Clinic Ethics Council.

Mueller received his medical degree and Master of Public Health degree from Johns Hopkins University in Baltimore, Maryland. He completed residency training and chief residency in Internal Medicine at Johns Hopkins Hospital.

Mueller’s clinical practice encompasses primary care and consultative general internal medicine. U.S. News & World Report recognized him as a “Top Internist.” During his time at Mayo, Mueller received awards for teaching at all levels of medical education. He continues to teach at Dell Medical School. Mueller’s research focuses on ethical dilemmas associated with life-sustaining technologies, especially implantable cardiovascular devices. He has mentored many biomedical ethics scholars, and the first endowed professorship in biomedical ethics at Mayo was established in honor of him. He has authored 140 peer-reviewed publications and hundreds of book chapters and columns.

Mueller is a member, fellow, and master—the highest recognition—of the American College of Physicians.
