Errol Toran, D.C.​

Dr. Toran (a Manhattan born New Yorker) began his practice in 1986, providing chiropractic and rehabilitative care to athletes of all disciplines, performers in all areas of theater, as well as New Yorkers working in all forms of office environments.

Pilates has been an integral part of the consistently superior outcomes of his therapeutic and rehabilitation protocols. From working with the athletes, he learned how beneficial regular training and body conditioning are to performance.

The simplicity of Pilates movements as well as the minimal equipment demands made Pilates a superb training choice. Dr Toran was able to incorporate Pilates principles into the rehabilitative programs of his patient's active care and then in their home programs. The performers were able to take their healthcare management on the road across the country and around the world.

He found that his patient base, the athletes, dancers and regular folks returned to work faster and were less prone to future injury. Dr Toran and his wife Ann have spent the last two decades fulfilling their mission of making Pilates "Affordable for Every...body!!!".

Their company, Pilates Reforming New York, was opened in 2002 incorporating a revolutionary business model providing Group Reformer Classes. Dr Toran is also a Balanced Body Educator, teaching Anatomy to Pilates teachers around the world.
