Phelan was born in Princeton, New Jersey.[3] Her father founded a health service company, where he was also the chief executive, and her mother is an international tax consultant and partner at a national public accounting and business advisory firm. Phelan explained that her parents liked the idea of "unity", hence her unusual first name.[2]
Phelan started ballet at age four at Princeton Ballet School, following her older sister. At thirteen, she attended the summer program at the School of American Ballet in New York, and was invited to join the year-round program. Her parents thought she was too young, but allowed her to train there full-time the following year.[2] She trained at the school for three years.[3] During this time, she also completed high school at the Professional Children's School, and graduated in 2012.[2]
Career
Phelan became an apprentice with the New York City Ballet in 2012,[3] and joined the corps de ballet the following year.[4] Roles she danced whilst in the corps de ballet include in Balanchine's "Stairway to Paradise" in Who Cares?,[5]Episodes,[6] first pas de trois in Agon and a demi-soloist in Symphony in Three Movements.[3] In 2015, she made her debut as the Sugar Plum Fairy in Balanchine's The Nutcracker.[7] In 2016, she was chosen by choreographer Christopher Wheeldon to create a lead role in American Rhapsody,[8] and by Lauren Lovette in For Clara.[9] Later that year, she debuted as Dewdrop in The Nutcracker.[10] The following year, she originated a role in Pontus Lidberg's The Shimmering Asphalt.[11]
In 2017, she performed a pas de deux in Balanchine's Agon with then-American Ballet Theatre soloist Calvin Royal III, with Arthur Mitchell, who originated Royal's role, in the audience. Following the performance, Mitchell commented the ballet was "in good hands."[26] The following year, after Mitchell's death, Royal and Phelan reprised the Agon pas de deux at his memorial.[27] The same year, following the collaboration between New York City Ballet and Puma, she took part in the latter's promotional tour in Asia.[28]
While dancing full-time, Phelan also studied at Fordham University. She graduated in 2020, with a bachelor's degree in economics and organizational leadership.[2][33]
In 2022, Phelan married Cameron Dieck, a former New York City Ballet dancer.[2]
^At the New York City Ballet, the composer's last name is spelled "Tschaikovsky" rather than "Tchaikovsky" as he used the former spelling during a visit to New York in 1891.[34]
