I found USSD on groupon and I'm glad I did it's a great. USSD Instructors are awesome very friendly and great with the kids. They have various class's and styles of martial arts that the kids can learn if they choose to do so. My son is excited to learn and that's makes my wife and I very happy that he will able to defend himself. I recommend it parents who want their kids to learn self defense and build confidence in them selves.
