After completion of medical school Dr. Redford finished a fifth pathway at the University of Maryland. Unsure about which area of medicine to pursue, he trained in several fields of medicine and surgery until he discovered the field of Anesthesiology. After completion of training in Anesthesiology he relocated to Washington state where he was in private practice for many years. Dr. Redford worked with the Department of Defense for several years where he trained military Anesthesiology residents, military student nurse Anesthetists and served as consultant to the U.S. Assistant Attorney Generals Office. In 2001 he moved to Tucson where he joined the faculty at the University of Arizona. Dr. Redford has pursued his academic interests which have included pulse oximetry, noninvasive hemodynamic monitoring, the hemostatic coagulation system and blood coagulopathies.
