Mitchell Professor and chair of internal medicine at the University of South Alabama College of Medicine. No kidding: Crook said that at one point in 2020 he had to make arrangements to isolate from the rest of his family, because he was seeing patients while his daughters had to return back home from graduate and undergraduate school.
