Ballerina Melissa Bierstock opened this successful midtown studio in 2001. She has since moved to New York, but another former ballerina, Leslie Parker, now owns and runs it. Certified in the Pilates method, her staff teaches private, semi-private and group sessions, with a maximum of 10 students per class. Group lessons focus on mat and ball work; private sessions may include the use of such specialized equipment as the Reformer and Cadillac. From the Center also offers injury recovery and prevention courses, and pre- and postnatal classes, along with 10- or 16-week pre-wedding sessions.
