The Japanese Karate-Do dojo was founded by Sensei Sonny Kim in 1996, based on the principles of personalized training, specifically design toward each individual's needs and abilities. 

Today the dojo is continuing with the same principles under the guidance of Sensei Rob Grossheim.


We welcome anyone who wants to learn Karate, from beginners to those who simply want to improve and develop their current skills and those who want to expand their skills and techniques to a much higher level.


Aside from being one of the most effective methods of self-defense, Karate is an excellent form of stress management and aerobic exercise for the entire family. Using all the muscle groups, karate training develops flexibility, coordination, balance, posture, and muscle tone. It is a great way to improve your health and overall fitness.


If you want to understand the heart of martial arts, become physically fit and/or gain an overall sense of physical, mental and emotional well being, you owe it to yourself to look into Japanese Karate-Do.


Go through our website and get to know us a little better. But, our website can only give you a small taste of what the Japanese Karate-Do has to offer. So, come and visit the karate school, watch some of our classes in the visitor viewing area or better yet, make an appointment to participate in one of our Introductory Lessons.
