I have been a student/client there, off and on, for about two years and I find that the instructors are among the most knowledgeable, personable and professional people in the movement. I've been doing gyrotonic for more than eight years and have had many amazing teachers. When I came back to New York, I tried Chelsea Movements out and found they not only had some of the best prices for classes and one-on-one training, they also have a clean, intimate, conveniently located studio space.
