Martial arts is a great opportunity for special needs kids for both general exercise and crosspatterning exercises which improve brain function. It also instills a sense of competence and self regulation.
Patrick Diez is a karate instructor who has worked with many special needs students and does an amazing job of adapting the moves and program as needed. He is skilled at giving the child a positive experience, correcting them without ever putting them down.
He has worked with ADHD, AS, and HFA kids. He is excellent with quirky behaviors. One of his star pupils has CP and had difficulty with walking and balance; he helped build up her core strength.
