Sarah Chalke is not a doctor - but she plays one on TV as a motivated young medical resident, and she even researched the role by going on hospital rounds with a group of actual doctors. "Normally, I pass out at the sight of blood being drawn," says Chalke, who starred for several seasons on "Roseanne." "But, I'm way over that," she jokes, "Now, I perform complete procedures on my friends." Chalke was born in Ottawa, Canada, and raised in Vancouver, Canada, as one of three daughters. Her father is a lawyer and both her parents are mediators who also run a child adoption agency. Two years ago, she accompanied her parents to China to coordinate the adoption of several orphans there when the family decided to take a side trip to neighboring Tibet. After hiking to a native "sky burial" at 17,000 feet, Chalke experienced a frightening incident when her father became severally ill with high-altitude sickness. "Waiting to go down the mountain was the most intense night of my life," she recalls, but her father survived. When Chalke was eight years old, she began appearing in local Vancouver musical theater productions ("until I discovered that I couldn't sing"). A few years later, she became a youthful environmental reporter on the Canadian series "Kids' Zone." Chalke then got her big break in 1993 when she was cast as daughter Becky Conner in the hit comedy "Roseanne," replacing actress Lecy Goranson. When "Roseanne" concluded in 1997, the outdoorsy Chalke returned to Vancouver and gladly remained in her hometown, where she starred for two seasons in her favorite role as a cowgirl in the Canadian series, "Nothing Too Good for a Cowboy." Her television movie credits include "I've Been Waiting for You," "Stand Against Fear," "A Child's Wish," "Dying to Belong," "Our Mother's Murder," "Dead Ahead" and "Woman on the Ledge." Chalke has returned to comedy as she portrays an ambitious, but socially awkward intern who is not afraid to speak her mind. "She's kind of a smarty-pants," says Chalke. "She's sarcastic and fun, competitive and driven, but also has a lot of insecurities and is a bit of a klutz. Although she tries to keep up a tough façade, she's really just nervous about being a good doctor." During her summer hiatus, Chalke had roles in two movies - "Cake," co-starring with Heather Graham and Taye Diggs and "Alchemy," co-starring with frequent "Scrubs" guest star Tom Cavanagh. In her leisure time Chalke prefers cooking with friends (especially Thai and sushi), playing the guitar, hiking, skiing (she's an instructor), snowboarding, kayaking and reading. In addition she speaks French and German. She also volunteers at a hospice for terminally ill children and works for the Audrey Hepburn Children's Fund. Chalke currently resides in Los Angeles.
