Business Review

“In addition to improved physical conditioning, balance, flexibility, strength, and coordination, I think the changes in my life due to my martial arts training include: a positive attitude, patience, perseverance, and self-confidence, with a great deal of respect for myself and others.”  —male, age 17, high school student

"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."  -- female age 32, corporate employee

"My teachers have helped me cope with the "bullies."  I no longer look at myself as a loser, 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
