Born and raised in Ottawa, Canada, Sandra Oh started ballet lessons at the age of four and performed in her first play, "The Canada Goose," at the age of ten. She started working professionally at age 14 in television, theatre and commercials.
After three years at the prestigious National Theatre School of Canada, Oh beat out more than 1000 other hopefuls and landed the coveted title role in the CBC telefilm, "The Diary of Evelyn Lau," based on the true story of a tortured poet who ran away from home and ended up a drug addict and prostitute in Vancouver. Her performance brought her the 1994 Cannes FIPA d'Or for Best Actress and a Gemini (Canada's Emmy) nomination for Best Actress.
Oh moved to Los Angeles in 1996 to begin the first of seven seasons as Rita Wu, the smart and sassy assistant on the HBO comedy series, "Arli$$," winning a Cable Ace Award for Best Actress in a Comedy. Additional television credits include HBO's "Six Feet Under," Showtime's "Further Tales of the City" and "Judging Amy."
She has been nominated for multiple Emmy Awards and won a Golden Globe Award (Best Actress in a Supporting Role), a Screen Actors Guild Awards (Outstanding Performance by a Female Actor/ Cast in a Drama Series) and a Diversity Award (2005 Creative Liberty Award) for her portrayal of Cristina Yang on "Grey's Anatomy." Most recently Oh jumped the pond for SKY1's "Thorne: Scaredy Cat," which will air in the U.S. on Starz Encore.
In film Oh won her first Genie (Canada's Oscar) for her role in "Double Happiness" in 1994, a bittersweet coming-of-age story about a young Chinese-Canadian woman. She won a second Genie for Best Actress in 1999 in Don McKellar's critical indie, "Last Night." For Alexander Payne's "Sideways" she received a Screen Actors Guild Award for Outstanding Performance by a Cast in a Motion Picture. Other feature credits include "Under the Tuscan Sun," "The Princess Diaries," "The Night Listener," "Hard Candy" and "Dancing at the Blue Iguana." Indie credits include "3 Needles," "Guinevere" and "The Red Violin." Most recently Oh starred alongside Nicole Kidman and Aaron Eckhart in the drama "Rabbit Hole," and in "Ramona and Beezus."
Oh has also lent her voice to the animated series "American Dad," "Phineas and Ferb," "Robot Chicken" and "American Dragon: Jake Long," to the animated films "Mulan 2," "The Land before Time: Wisdom of Friends," and to the award-nominated radio play "The Maltese Falcon."
Returning to her theatre roots in 2006, Oh starred in the play "Satellites" at New York's Public Theater for playwright Diana Son. She has also starred in the world premieres of Son's "Stop Kiss," for which she received a Theatre World Award, Jessica Hagedorn's "Dogeaters" at the La Jolla Playhouse, and "Oleanna" at the Grand theatre and National Arts Centre in Canada. She was also seen in the "Vagina Monologues" in New York.
