I have never been disappointed. Master Ott places his students in classes according to their skill level and maturity, so he is able to help them perfect their skills without the pressure of keeping up with advanced kids. He is very concerned with teaching his students the correct way to do kicks, punches, and forms. He also demands respect and obedience from his pupils. Amazingly, in 8 months I have never heard him lose his temper or raise his voice with them. Perhaps what I most appreciate about Master Ott is his character.
