Alvin Wee, DDS, PhD, MPH, wears plenty of hats in his position at the School of Dentistry. He is the Director of the Division of Prosthodontics, a leader in care for patients with complex oral rehabilitation needs and a researcher focusing on color sciences and early detection of oral cancer. But one of the obligations he treasures most happens outside the walls of Moos Tower: serving in private practice at the Minneapolis VA Health Care System.
