Sally's parents, both amateur ballroom dancers, laid the groundwork for her future in dance. By the time she entered first grade, Sally had already begun taking dance classes, a passion that would only continue to grow. Upon graduating from high school, she was signed by MGM, and in 1945, she made the move to Hollywood with her parents.
Sally's early days in Hollywood were filled with hard work, as she contributed to the dances featured in films such as Till the Clouds Roll By (1946) and The Kissing Bandit (1948). However, after a period of unemployment, she took on small roles until she teamed up with Ida Lupino, who was producing and directing small films at the time. Sally was cast in the lead role of Not Wanted (1949),a critical and commercial success that also earned her critical acclaim.
Following her success in Not Wanted, Sally appeared in a few more of Lupino's films, including Never Fear (1950). She eventually returned to MGM, where she worked alongside stars such as Boris Karloff and Red Skelton. When her husband, Milo O. Frank Jr., relocated to New York, Sally followed, pursuing a career in summer stock and on Broadway in the stage play "The Seven Year Itch".
Sally's film career slowed down after her move to New York, but she did appear in a couple of movies, including While the City Sleeps (1956),in which she reunited with Ida Lupino.
