Born in Nelsonville, Ohio, Parker landed her first Broadway role at the age of eleven in The Innocents, and following that, performed in the national company of The Sound of Music with four of her seven talented siblings. She went on to star in the lead role in the musical Annie for twelve months, moving on to television to star as the brainy, awkward Patty Greene in the CBS sitcom Square Pegs. After graduating from Hollywood High, Ms. Parker chose to pursue acting full-time and won regular roles in the television series A Year in the Life and Equal Justice. Among her numerous television credits are starring roles in The Sunshine Boys, In the Best Interest of the Children, Twist of Fate, The Room Upstairs and The Ryan White Story.
Ms. Parker continues to perform on stage, last year playing the lead role in the Tony Award-nominated Broadway musical comedy Once Upon a Mattress. Other stage credits include the lead role in Sylvia, a performance which earned her a Drama Desk Award. She also appeared in How To Succeed in Business Without Really Trying, opposite her husband Mathew Broderick.
