Locally, The Red Dragon School of Martial Arts under Sifu Bob Gott is the home of the official regional Yang Chengfu Tai Chi Center, Yang Chengfu being the lineage of Yang Style taught. Also a practitioner of Hung Gar Kung Fu, Sifu Gott competed and won medals in China, in part to earn his title as head of the center, taking over from the Morning Light School in East Aurora, formerly run by Jim Fox.
This lineage focuses on opening and expanding the joints, lateral interpretation of movements, and detailed stance transitions. It uses the “10 Principles” but lists them in a non-traditional order. In addition to a traditional-length set (divided into three sections), there are also sword and saber forms, as well as a smaller competition form.
I studied under Sharon Waters and Sifu Bob Gott for over a year, many times a week, and it is under their arrangement that I currently teach at the VA Recovery Center.
They have many classes throughout the week, and their website can be found here.
