Nichols became an apprentice with the New York City Ballet in 1974, shortly before she turned 16. She was hired as a full company member later that year. Nichols worked closely with Balanchine. The various ballets by Balanchine she was known for include
Serenade,
The Nutcracker,
Liebeslieder Walzer,
Kammermusik No. 2,
Divertimento No. 15, Following an unusually long 33-year career, Nichols retired from the New York City Ballet in 2007, shortly before she turned 49. In her farewell performance, she danced
Serenade as the Waltz Girl, ''Robert Schumann's Davidsbündlertänze
and "Der Rosenkavalier" from Vienna Waltzes'', all three were choreographed by Balanchine. At the company, she staged Balanchine's
Concerto Barocco and
Serenade. In 2017, she left to join the faculty of
Indiana University Jacobs School of Music as Violette Verdy and Kathy Ziliak Anderson Chair in Ballet and professor of music in ballet, succeeding
Violette Verdy, who died the previous year. In 2023, Nichols returned to New York City Ballet for the first time since her retirement to coach three ballets, including Robbins'
Rondo, for the company's first performances of the ballet since 1980, as well as Balanchine's
Walpurgisnacht Ballet and
Donizetti Variations. ==Personal life==
