Known to many as Dr. Sydney Heron on the medical drama Grey's Anatomy, Kali Rocha seems to be an eternally familiar face, due to her numerous appearances in such a variety of projects. After growing up in Rhode Island, Rocha attended the Carnegie Mellon School of Drama before embarking on a professional acting career with a role in 1996's The Crucible. Subsequent projects found her playing everything from a fun-loving demon on Buffy the Vampire Slayer to an all-business social worker in White Oleander. ~ Cammila Collar, Rovi
