Dr. Hansen received his DVM from Purdue in 1980, then did an internship at the University of Illinois before entering private practice in South Bend, IL until 1985. In 1985, he started a residency in internal medicine at The Ohio State University and then earned a Master's degree in 1990. His primary clinical and research interests include critical care and recognition and treatment of pain. Dr. Hansen rides his bicycle 5,000-7,000 miles every year, and enjoys some racing and recreational road riding in the Blue Ridge Mountains. He also builds telescopes and monitors the climate changes on Mars. He is married and has a gymnast/equestrian daughter.
