Walters was born in San Francisco, California, and was, by several years, the oldest of the eight actors playing the Bradford children, though her character, Joanie Bradford, was the third-oldest child in the family. Walters is six months older than Betty Buckley (born July 3, 1947), who played her character's stepmother. Walters' first screen role was as Sheila Grove in 1973's The Harrad Experiment.
Walters made guest appearances on a number of other television series through the 1980s, such as Cheers and Highway to Heaven, as well as on two Eight Is Enough reunion specials, but she has not acted on television since 1993.
Walters, as of 1999, lived in Los Angeles, where she worked as an environmentalist.[citation needed] More recently, she has acted in plays in the Southern California area and directed theater productions in Ojai, California, under her married name, Laurie Walters Slade. Walters was later in charge of film acquisitions for a subscription-based film service called Ironweed Films.
