Nicole Sullivan, a native New Yorker, has been acting since she was seven. She attended Northwestern University, where she spent four years studying the classics, including Shakespeare and Chekhov. After graduating on the Dean's List, she joined the Greenwich Shakespeare Company.

Sullivan moved to Los Angeles and spent several years honing her waitressing and temping skills until she was hired by MAD TV as their youngest cast member. In the six years she worked on the FOX late-night sketch comedy show, she became known for her many recurring characters -- such as the Vancome Lady -- and her sometimes scathing impersonations of celebrities like Britney Spears and Meg Ryan.

In 2001 Sullivan joined the cast of King of Queens as Holly, the dog-walker. Her numerous television guest appearances include such shows as Scrubs, Law & Order: SVU, Monk, According to Jim and Party of Five. She has also been a guest on The Tonight Show with Jay Leno and The Late Show with David Letterman.

In addition Sullivan lends her voice talents to a number of animated television shows, among them Kim Possible, Family Guy and Buzz Lightyear of Star Command.
