Kate Walsh was born on October 13, 1967, in San Jose, Californa, and was raised in Tucson, where Kate attended the University of Arizona. Kate began her professional acting career doing theater in Chicago, and her first major television appearance came on "The Drew Carey Show" as Drew's girlfriend. Later she played Norm McDonald's love interest on the sitcom "The Norm Show." In the family movie "Kicking & Screaming" she played Will Ferrell's wife but is best known for her role as Dr. Addison Shepherd on the television show "Grey's Anatomy."

Kate Walsh may have an impressive list of film and TV roles on her resumé, but her primary acting venue has always been the stage. Starting out in regional theater in Tucson, AZ, where she went to college, Kate later got involved with the Piven Theatre Workshop and Shakespeare Repertory in Chicago, as well as the comedy troupe Burn Manhattan in New York.

Walsh was in her late twenties in the mid-90s and began slowly but surely making the transition to the screen with appearances on TV shows like Homicide: Life on the Street and Law & Order. Walsh's list of film and TV appearances soon grew huge, and among her scads of roles were a number of prominent parts on very popular shows. She became a regular on The Drew Carey Show in 1997, donning a fat suit to play Drew's weight-struggling girlfriend, and in 2001, she took a recurring role on the HBO series The Mind of the Married Man.

Walsh joined the cast of the smash-hit series Grey's Anatomy in 2005, playing Dr. Addison Montgomery-Shepherd, estranged (and eventually ex-) wife of "Doctor McDreamy," Patrick Dempsey. Walsh suddenly went from a working actress to a well-known face, and it looked like the perfect time for the actress to step onto the big screen. She signed up to indulge in a little magic with the fantasy adventure Veritas, Prince of Truth alongside Sean Patrick Flanery and Amy Jo Johnson.
