Into Season 11, Susan begins to build some anxiety about the upcoming tenure offer. It ultimately goes to her friend John Carter, due to her lack of grant funding, finally leading to her final exit from the series at the beginning of Season 12 in the episode "Canon City". Susan is offered a tenure track position at a hospital in Iowa City, Iowa (presumably University of Iowa). Technically, Stringfield was the first and last original cast member to leave the show. (Being the first to leave in 1996, then in 2005 after the rest of the original cast left.) This was later bested by Noah as he returned in the final season of E.R in 2009.
