corps de ballet in March 2007, was promoted to
soloist in June 2011 and principal in August 2014. Lead roles she danced include Nikiya in
La Bayadère, Kitri in
Don Quixote and Columbine in
Harlequinade. Boylston won the
Princess Grace Award in 2009 and was nominated for the 2010
Prix Benois de la Danse. Outside of ABT, she also designed costumes for the
Pacific Northwest Ballet's 2010 production of
Benjamin Millepied's

Steve Reich's
Three Movements for Orchestra. She has appeared as a guest artist with the
Mariinsky Ballet in St. Petersburg and the
Royal Danish Ballet. In 2019, she helped breaking the
Guinness World Record for the most dancers ever to go on pointe at the same time, alongside
James Whiteside on
Live with Kelly and Ryan.
Alastair Macaulay of the
New York Times noted Boylston portrayal of Lise in
La Fille mal gardée is "intimate, heartfelt, rapturous." On
Swan Lake, Macaulay praised Boylston's musicality and phrasing. In 2020, Boylston participated in
Misty Copeland's fundraiser, Swans for Relief, by dancing
The Swan, in light of the
impacts of the 2019-20 coronavirus pandemic on the dance community. The fund will go to participating dancers' companies and other related relief funds. ==Selected repertoire==
