The physics and biomechanics of tennis strokes are quantifiable and open source. The perception of what is correct, ball striking, and match play are unique for each individual and the possibilities for success and failure are unlimited. My lessons differ in two ways from a typical tennis lesson. All strokes are based and backed by science and the laws of physics. I was fortunate to have a brother Dr. David DeYoung who was one of the leading astrophysicists in the world. His work in radio astronomy was leading edge in the discovery and study of black holes in space. He was one of the founders of the virtual observatory and served as the chief project scientist and the first president. (virtualobservatory.org) He was a constant resource and a consultant guide for my teaching methods.

Another reason that my lessons are unique is that I incorporate innovative tennis inventions of teaching and learning that are not used anywhere else. As a tennis inventor in teaching aids I have U.S. utility patents granted in my name and have had licensing agreements with Prince Mfg and Wilson Sporting Goods in the field of tennis teaching aids. Aerospace engineers have helped design and make these products. Your tennis will improve exponentially with this system.
