Bruce at that time was building a group, but a very special group, no novices. He was looking for guys who were seasoned street fighters. Each member brought very different skills to street fighting and Bruce wanted to pit his Gung Fu against them to find out what worked and what didn't. In return, Bruce would teach them Wing Chun so he would have people to train with. Jesse Glover, Taky Kimura, Ed Hart were already a part of this group, when DeMile joined. Bruce taught them what worked and with their help, started modifying Wing Chun. "His only interest was fighting," DeMile said. "He would analyze techniques, break them down to their simplest form and make them as effective as physically possible."

One of the foremost authorities on 'Modern Wing Chun', DeMile has adapted Bruce's modification of the ancient art of Wing Chun and created Wing Chun Do, a practical self defense system. DeMile is listed in Bob Wall's Who's Who in the Martial Arts, and The Genealogy of Ving Tsun (Wing Chun) Family. He has written many articles for national and international magazines. He has written four best selling martial art books as well as produced a number of training videos, including "Bruce Lee's One and Three Inch Power Punch". DeMile travels extensively throughout the world teaching his dynamic self defense concepts and techniques to students, police and the military. Sijo (Founder) James W. DeMile presently teaches at his International Headquarters in Kailua-Kona, Hawaii.
