Martial Arts Instructors

Michael Chang
Martial Arts Director
Tai Chi and Unified Movement Instructor

More recently, he studied Chinese Traditional Long Fist, Baiji, Tongbei, Piqua, and Chen Tai Chi with Narcyz Latecki. In 2010, Michael competed in the Los Angeles International Wushu Tournament  where he won first place in Tai Chi, and placed second in  kung fu in the over forty group.

Over the years, Michael has helped coach many national and international champions.  His most recent students have won gold medals at the Hong Kong International Kung Fu Festival and the 2009 World Guoshu Competition.

Michael started ballet and gymnastics as an adult and enjoys its many challenges.  Michael is currently a member of the Cambridge Community Gymnastics where he still regularly takes classes.

As a result of these interests Michael has a unique perspective in how athletes and dancers train in each discipline.  That and his qigong training allow him to take the best of all worlds and coach each art with a logical sequencing.  The result is a East/West cross training method based upon qigong, body mechanics and the physics of movement.  Efficiency and ease of movement, internal and external energy utilization are what makes his coaching and his classes unique.  He has created a unified curriculum which allows for a true mind body experience.  His mantra is, “train smarter not harder”.   Based this philosophy, Michael has lead seminars in Qigong to ballet dancers at Boston Ballet, Festival Ballet, Ballet Brio and the International Ballet Academy of Norwell.
