My son has been training with Mr. Quillen since he was 4 years old. (He's 8 now.) Mr. Quillen is a great guy. He is wonderful with the kids. He knows how to be firm with them and get things done but also has a good sense of humor and makes class fun. He is a great motivator and knows how to help people achieve their best and feel good about themselves. I highly recommend Moo Sa Black Belt Academy. Try it for youself, your child or both of you, I guarantee you won't be disappointed!
