About the School





Mission Statement for the Jeet Kune Do Classes

Promoting martial arts in Connecticut, USA

Bruce Lee obviously had some exceptionally eclectic ideas for the way he put his fighting scheme together. His training methods for developing the tools needed for fighting, as many people in martial arts now know, was a bit ahead of its time. It was also a big influence on the way some martial artists practice today. The goal at the PSDTC is to carry on these teachings of Bruce Lee, along with his concepts, which is the way Ron’s teachers had taught him Jun Fan Gung Fu/Jeet Kune Do. Needless to say, the evolution of Jeet Kune Do is also included in this program. Of course, exploring other styles to pick what works for you or at least seeing how they tick, being the way of JKD, there will be a distinctive characteristic touch in Ron’s way of teaching. Which is obviously influenced by all the other martial arts and all the instructors he has trained with.

The goal is to get students to understand the art as well as the science, as a result, the self-defense potential that JKD and the related martial arts has to offer. This is so students don’t just memorize the movements to advance in the ranks in JKD. At the PSDTC, the students go through the training methods that develop the tools needed for the proper reflexes if an actual self-defense situation should ever occur. Ron’s goal is also to help students get into shape through his advice in proper nutrition along with the appropriate physical conditioning exercises that will enhance their endurance and their all around feeling of well being. All students get the proper education and personal attention from the instructors at the Practical Self Defense Training Center together with the more advanced students to develop those good fighting reflexes. As a result, this goes along with the understanding of how to be street-wise to ensure safety and confidence that every student who studies at the PSDTC can keep with them forever, anywhere they go. Most of all, watching all PSDTC members having fun while training and seeing everyone enjoy what they are learning has always been and still is a very successful goal of the school.
