Our Instructors

A Message from Ron Kosakowski
Practical Self Defense Training Center Founder and Head Instructor

To all who are looking to train in Jun Fan Gung Fu / Jeet Kune Do and Kali, these guys have a lot to offer. So if it is convenient to travel to either one of the instructors below, feel free to e-mail or call them to find out more information. I keep a tight watch on all my students, even if you are training with another student of mine to ensure quality control that is lost in many martial arts now a days. I hold bi-monthly workshops (see events section) to keep everyone on the same page, though freedom of expression still exists. We want to be one big happy family to train together without the usual politics that occur constantly in other styles. Good luck in your quest and we will see you training soon!
