Cassidy McAndrew began her ballet training at age five in Stamford, CT. At eleven, she continued her training at Ballet Academy East (BAE) under the direction of Darla Hoover. Upon graduating from BAE in 2015, Cassidy joined Charlotte Ballet as an apprentice for the 2015–2016 season, where she was mentored by the legendary Patricia McBride.
She went on to dance with Pennsylvania Ballet (now Philadelphia Ballet) for four seasons, performing corps de ballet and soloist roles in works by Angel Corella, Jerome Robbins, George Balanchine, Ben Stevenson, Sir Kenneth MacMillan, Alexander Ekman, Matthew Neenan, and Helen Pickett.
In 2021, Cassidy moved to California to join the Los Angeles Ballet for the 2021–2022 season. Since 2022, she has been freelancing in the greater Los Angeles area, dancing with companies including Ballet Project OC, The Realm Company, and Inland Pacific Ballet.
Cassidy began teaching in 2020 and has taught at notable institutions such as Ballet Academy East, Los Angeles Ballet School, Westside School of Ballet, and Inland Pacific Ballet. Now relocated to Bozeman, she is thrilled to join the faculty of MBC and continue sharing her knowledge and love of ballet.
