Weekly company class is also a beloved feature of Columbia Ballet Collaborative at New York City’s Columbia University. “It’s nice because people who aren’t cast that semester can still come,” says CBC artistic director Willa Broderick, a junior at Columbia College studying sustainable development and a graduate of Boston Ballet’s pre-professional program. Both she and CBC’s executive director, junior Madeline Angelides, supplement CBC class and rehearsal with technique classes through the affiliated Barnard College’s dance department. Angelides, who attended The Rock School, is pursuing a combined major in economics and statistics at Barnard. The duo produce CBC’s twice-yearly performances, which showcase a mix of guest and student choreographers and classical repertoire. This fall’s lineup includes choreographer Courtney Cochran and Black Iris Project artistic director Jeremy McQueen, among others. “It truly functions like a mini dance company,” says Angelides. “Just one that’s run by 20-year-olds.”
