Meet The Faculty

Mayo Clinic radiologists and staff provide the highest quality diagnostic and interventional imaging services in a caring and efficient manner while sustaining outstanding programs in research and education.

The division of interventional radiology is staffed by eight board certified interventional radiologists who bring a wealth of diverse clinical experience and research interests to your training. Their broad training throughout the country, connections in the field, and research footprint will not only strengthen your training but also facilitate your search for academic and private practice positions toward the end of your residency.

The Department of Radiology is fully integrated with all the medical services available at Mayo Clinic. More than 60 radiologists, 10 physician extenders and five physicists cooperate with hundreds of support staff to provide diagnostic and therapeutic radiology services to patients.

Experts in all areas of radiology consult with specialists in other departments to provide the best care to every patient every day, consistent with Mayo's mission. Radiologists work with state-of-the-art equipment, assisted by skilled technologists and nurses, to perform and interpret more than 320,000 examinations yearly. This considerable number of cases, integrated with ongoing research and education, results in wide-ranging expertise in the imaging and treatment of diseases affecting patients of all ages.

In addition to caring for patients in their clinical practices, Mayo Clinic's faculty members are committed to teaching and facilitating the growth of medical knowledge. Many of our faculty have published and lectured extensively and are recognized leaders in their fields. You have direct access to these individuals throughout the residency.
