"The Self-Defense Institute's instructors keep the classes interesting and challenging by constantly instructing new things to learn. I have thanked my instructors for the opportunity to improve my health and physical abilities - bike riding and aerobics were getting old and I needed a new activity. I received more then a new activity. I received a program that has developed my ability to keep up with my children. My energy level has soared since training with The Self-Defense Institute."

"My instructors have helped me cope with the "bullies." I no longer look at myself as a looser, but as a person who cares about everyone. As I get stronger muscles, my mind is getting clearer. I have learned to respect my teachers and my family, not because I look stronger, but I feel stronger with my thoughts. My teachers taught us that "If you say you can, then you will!" Classes are fun and I've learned a lot how to deal with the bullies, and that respect and honesty are very important parts of life." - age 11
