[2] Crofton studied ballet under Russian dancers Olga Preobrajenska, Nikolai Legat, and Laurent Novikoff.
[2] Crofton then danced with the Chicago Lyric Opera Ballet before touring Europe with Bronislava Nijinska's company.
In 1966, she relocated to New York City when Alicia Markova, the ballet director of the Metropolitan Opera, invited her to teach.
[2] Following the tour, Crofton's company and school was suspended due to financial uncertainty from their original funding body, the Metropolitan Buffalo Association for The Dance.
Before the company could get off the ground, however, Cofton suffered a heart attack at her desk in Rochester, and died on 30 November 1979.
