Jun Fan Gung Fu / Jeet Kune Do
Filipino Martial Arts such as Kali, Arnis, Eskrima (also spelled - Escrima) and Kun Tao

As you walk into any martial art school, you should be able to see right away if the training methods taught there will fit your personal needs.  At the PSDTC, we teach a science: you are not just memorizing individual techniques and hoping you remember to pull them off in a self-defense situation.  They are a system, and they really work.  This is not "sport karate" and we do not practice kata (AKA - "forms").  You will learn training methods and drills that were taught to warriors in ancient times updated and applied to today's world and street-oriented self-defenseto help you to respond spontaneously if a situation should occur. These training methods are unique to the martial arts Ron had spent three decades learning and perfecting. 

See why peoplefrom martial art teachers and artists from other schools, to fighters, to law enforcement and military personneltravel from all over the US and Canada to train at Ron Kosakowski’s Practical Self Defense Training Center.  Check out other schools to compare so you can see the differences for yourself.  Don’t be taken by fast talkers; actions speak louder than words… Our program speaks for itself at first glance.
