Born in Alexandria, Louisiana, Faith was raised in nearby Pineville. In high school, Faith acted in school plays and, in her senior year, was a finalist in Teen Magazine's annual model search. At 17, she was in New York where she worked in commercials and did some modeling. Soon Faith had recurring roles in soap operas such as "Muffy" in One Life to Live. In 1984, Faith made the move to Hollywood. Faith found prime time work as Janine, the fumbling secretary, on thirtysomething as well as guest spots on other shows. Her big screen debut was in the seldom seen You Talkin' to Me?. In 1988, after first turning down the role, she joined the cast of the Television series Murphy Brown as Corky, the blond. Over the years, Faith has received 5 Emmy nominations for her character and has seen Corky mature from the beauty queen ditz to the lightweight fluff reporter. After nine seasons on Murphy Brown, Faith has tried to distance herself from Corky with the thriller Night Visitors and Her Desperate Choice.
