The room. Eight people per class, professional-grade Allegro 2 reformers, real space around each one, and instructors who work with you hands-on rather than calling out cues from the front.
Since 2011, in the same Mount Pleasant location. Several instructors have been teaching here for a decade or more, and we have clients who have trained with us for fourteen years.
Two group classes for $50 for new clients, including a full equipment orientation on your first visit. After that, single classes are $40 and packs bring the per-class price down.
