Hello Mr. Cox, My son Luca has been studying Tang Soo Do since December 2006. We are extremely proud of him and have seen such positive results in his everyday life, and his problem solving experiences. Luca has gained strength, confidence and trust in himself. Luca's listening skills and learning skills have sharpened greatly, and we feel it has made learning such a positive experience for him at the studio, home and at school. Luca's going all the way! Thanks, Allan & Tammy Goldenberg
