Walter Tapley

Walter Tapley is a doctor. He is Richard Webber's mentor. He visited the hospital in Losing My Mind and wanted Richard Webber to arrange an double valve replacement and tricuspid repair for him. Richard Webber eventually convinces Erica Hahn to do the surgery on him, after vehemently being against it as it's a very dangerous operation and extremely difficult to pull off.

Walter Tapley praises George for running around the hospital, saying it makes him a better doctor.
