Tai Chi Chuan classes and experiences for Long Island and beyond. Get started now! In the practice of classical Tai Chi Chuan, what is most often sought after is the combination of physical benefits with development of mental well-being and vitality. These two aspects go hand-in-hand and are not really separate considerations. The head teacher, Master David B. Alexander, has a wide background with Tai Chi Chuan, including 40+ years of study, practice, and teaching independently since 1990, as well as assisting Grandmaster William C.C. Chen in his workshops. He teaches the classic Short Form as well as push hands and punching.
