Cheryl Holdridge first performed professionally at the age of nine in the New York City Ballet’s version of The Nutcracker in Los Angeles. Her first screen appearance was as an uncredited extra in the 1956 film production of Carousel. She auditioned for Walt Disney’s The Mickey Mouse Club in the spring of 1956, was hired for the club’s “Red Team”—the most visible and popular of the Mouseketeers. Though a good dancer, her weak singing voice kept her in the background of most musical numbers performed by the Mouseketeers. A competent actress with a pleasant speaking voice, she was employed for two of the show’s episodic serials: Boys of the Western Sea and Annette. After the show’s run ended, Holdridge returned to Van Nuys High School and graduated from Grant High School with the winter 1961 class. She was cast in two episodes of Leave It to Beaver in 1959 as ‘Gloria Cusick’; she later played an occasional, recurring role as Wally Cleaver’s girlfriend, Julie Foster. From 1960, Cheryl Holdridge made guest appearances on over twenty different shows, including The Rifleman, My Three Sons, Bewitched, Bringing Up Buddy The Dick Van Dyke Show and Bachelor Father.

Cheryl Holdridge retired from acting in 1964 to marry race car driver Lance Reventlow, to whom she was wed until his death in 1972. After the death of her third husband, Holdridge made a cameo appearance in the 2000 feature film, The Flintstones in Viva Rock Vegas. In 2005, she appeared at Disneyland for 50th anniversary celebrations of both the opening of the park and The Mickey Mouse Club. She was cast in televised documentary specials about Cary Grant (2005) and Barbara Hutton (2006), and has also appeared in a special feature interview for a Disney DVD. Holdridge was a long-time supporter of environmental causes and charities including the Children’s Burn Foundation for which she served as a Council Member, and with her third marriage became more active in fund-raising events. Cheryl Holdridge died on January 6, 2009 from lung cancer, aged 64.
