When you join the KDA, you gain access to many benefits of membership. Primarily, of course, you get continual guidance from highly skilled and certified instructors, experienced evaluation for Dan and Gup rank promotions, the right to participate in local and international KDA tournaments, and dozens of other practical advantages.
But the best reason to join is for Dang Soo Do itself.
Dang Soo Do is not an easy martial art. But it is an art. And like any art the more you put into it, the more it will repay you. Dang Soo Do enriches you physically, mentally and spiritually; developing your Neh Gong, Weh Gong, and Shim Gong (Mind, Body, Spirit). And only with the KDA do you get a direct lineage to the highest ranking Dang Soo Do practitioner in the world, Choi Hee Suk, co-founder of the Moo Duk Kwan with Hwang Kee.
Because the KDA is here primarily for the preservation of the historical martial art of Dang Soo Do. And for this to be a reality, all of the aspects of the art must be preserved... not just the physical. The goal of the KDA is help you develop as a whole person in the way Dang Soo Do was meant to be taught.
