I am also someone who extensively investigated various martial arts studios in Springfield. However, I knew the first time I met Mr. Retana that he was the teacher that I wanted in order to learn the "unique and powerful art" of Kenpo Karate.  I have not been disappointed. I have been a student at Aaction Kenpo Karate for just over a year. I look forward to going to each and every class and the learning opportunites provided. Between classes, I am able to continue my education because of the excellent DVD tapes available to be used at home. These have been  invaluable to my progress.  A word to the wise. Do not expect this to be one of those studios that takes your money and "gives" you a belt. Mr. Retana is exacting and meticulous. If you are not committed to the art and prepared to advance then you won't advance. Personally, this makes every advancement in degree and belt more satisfying and rewarding.
