Before Saturday Night Live, Shannon worked as a hostess at Cravings restaurant on Sunset Boulevard and as a food demo girl at Gelson's super market in Marina Del Rey. She auditioned for her first big film role and was cast, playing the supporting part of Meg in the 1989 horror film remake of The Phantom of the Opera, with Robert Englund.

Shannon's major break came in February 1995, when she was hired as a featured player on Saturday Night Live to replace Janeane Garofalo after Garofalo left mid-season, reason being that the experience left her "anxious and depressed", and that she believed a sexist attitude pervaded the show. She said that many of the sketches were "juvenile and homophobic".
