Kirsten Baker made her film debut in California Dreaming (1979). Throughout the late 1970s and early 1980s, she worked as an actress in feature films and television, as well as a print model for Cannon Pictures.

This led to a modeling career which she pursued into the early 1990s. Circa 1993, Kirsten was no longer acting or modeling; she was employed at an art gallery on Melrose Ave. in Los Angeles, CA.
