1. Bully prevention is important now a days. See results in preventing that in only 6 months.
2. Our country is SUE HAPPY – if a child hurts someone even in self defense there is a high probability of a law suit. A grappling style like Brazilian Jiu Jitsu is the answer for children in today's society.
3. Watch how much better kids get in school due to the focus needed for martial art training...A BIG PLUS!

So, what do you do about this problem? Our Brazilian Jiu Jitsu classes are the answer to this problem. Its a non-violent approach to self defense. Guaranteed, your child will handle a self defense situation better once he or she learns the grappling methods of Brazilian Jiu Jitsu.

Come have your child try out a free class and see for yourself. We are 100% confident you will like what you see here at the PSDTC.




This class is designed for children age 5 to 12 taught by David Pannicia, a long time Brazilian Jiu Jitsu practitioner and competitor.

Children at that age, both girls and boys, Brazilian Jiu Jitsu, and wrestling with many of the takedowns, positions to submissions. To explain it a little better, the children learn escapes from all wrestling positions as well as defenses and counters against striking (i.e. kicking or punching). Its perfect for self defense for kids at that age.

Brazilian Jiu Jitsu for children is a less violent but yet still an effective approach to self-defense for the average situations they could possibly stumble upon at that age. For example, if a child has a confrontation, they can easily take their adversary down to any number of holds and/or a submission and usually a lesson will be learned without anyone actually getting hurt at all by controlling their aggressor as opposed to hitting their aggressor. Striking is taught the traditional Jiu Jitsu way to children for a complete understanding of all ranges that could occur in martial arts and of course for self defense purposes. Hitting techniques are taught only to be used in serious self defense situations along with common sense of it's use and of course for a complete exercise program with an all around understanding of the martial arts they are practicing.  


The exercise program at the beginning of the class is a science in itself and designed specifically to create a strong grappler. It is an intense workout that every child can slowly work his way into at his or her own pace. Every child eventually feels much stronger and more alert. It builds confidence as well as coordination due to how powerful; yet efficient this martial art essentially is that they are training in. All parents witness their child’s fullest potential brought from within as their self-esteem grows. You will see how they get stronger, their health, both mentally and physically improves. They develop discipline. Which in turn behaviorally habits always improve. The best one yet…you get them away from those video games and watching TV for a few hours a week. ***Statistics show, martial art training builds a great foundation in life for all children.**



Why put it off? Call Ron 203 802 8533 to sign up right now for the trial program and receive a FREE fitness evaluation. Get your child and/or yourself on the road to self-discovery that we guarantee will make every stage in life that much easier.


So what are you waiting for?  Don't wait till its too late!




As you can see these kids are  very focused on their training for perfection of technique. They learn timing, rhythm, footwork and how to do grappling without the use of strength! They are developing a real science that will be with them the rest of their lives!
