Berridge made her TV series debut as the bumbling maid serving a senator's family in the Norman Lear-produced "The Powers That Be" (NBC, 1992-93). She had greater series success as Eggers, the tomboyish cop, on "The John Larroquette Show" (NBC, 1993-96). Berridge has also appeared in several TV-movies, notably "Silence of the Heart" (CBS, 1984) and the "Hallmark Hall of Fame" production "Home Fires Burning" (CBS, 1989).
Due to her immediate entry into TV and film, Berridge did not begin to act on stage until 1984. Within two years, she had earned a Drama Desk nomination Desk Award for her work in three off-Broadway plays: ""Briar Patch", "Cruise Control" and "Wrestlers." Her first Southern California stage work, the lead in "Lulu" at the La Jolla Playhouse resulted in a 1989 DRAMA-LOGUE Award as Best Lead Actress.
