JDK is a martial art school located in Australia. Our lineage was brought out of Korea by GM Jhoon Rhee in the mid 1950s, installed into Southwestern USA since, and is led by GM Keith Yates' American Karate and Taekwondo Organization. We attempt to celebrate this lineage in a respectful and progressive manner. JDK trains by applying traditional techniques against unknown but predictable attacks, assuming resistance and possible failure, and then applying counters from our library of fundamental skills. One and all are welcome, and we share without reservation.
