Joong Do Kwan International
Delanson, NY, USA
Welcome to JDK USA! We opened our first JDK location in the United States in 2024! We started in Schenectady NY, but have now moved to the Duanesburg/Delanson area.
We will be training at the 4Everbods Fitness Club in Delanson, NY for this winter 2026/2027.
We are excited to bring high quality martial art material to the Capital Region, and surrounding areas!
The JDK Method equips the individual with an in-depth understanding of marital arts. First, we learn to utilize visualizations constructed during training. The practitioner can then can better focus in order to succeed during times of stress, facing violence, and daily life.
After developing the proper focus, the practitioner learns to apply visualization tools to into usable, combative material.
JDK USA focuses on the dynamics of non-consensual fighting, making it ideal for adults to learn self defense tactics. You can learn to protect your loved ones physically and guide yourself mentally.
JDK USA LLC is run by Instructor Will Just. Learn more about Instructor Just HERE.
