Master Cardenas is the absolute best that you will ever find anywhere. He is not only the absolute best at teaching Tae Kwon Do, but he teaches his students confidence, respect, honesty, a diligent work ethic, and integrity. He is very family oriented, is excellent with kids and adults, and he creates an atmosphere for the whole family to learn and fully enjoy.
Master Cardenas has been teaching my twins Taekwondo since they were 3 years old! Not only does he teach them the beginning techniques of taekwondo, but he teaches them real world skills--like being a "first timer" with your parents! As they get older, he continues these life skills along with the Taekwondo lessons.
Coming here has been one of the best experiences! My son began when he was just turned 5 and in the past 6 months I have been so impressed with the amount of growth, confidence and discipline he has learned!
