This Kuntao event will be canceled this year due to my son fighting that weekend for a championship MMA fight. I have to be there. However, I will be scheduling a 2 day Kuntao seminar soon so you do not miss out.

Thank you and stay in touch.



Our Annual In-Tents Kuntao camp will be coming up in:

July 28th, 29th and 30th 2017

This is one of our summer annual events that is always a big one.

If you are into learning Filipino martial arts, you will not want to miss out on this one. 


602 Southford Rd

Southbury, Connecticut

11 acres where you can pitch a tent to eat and sleep then train all day...and have fun.

Yes, July is hot. We solved that problem, there is a big in-ground pool to dive into in between training to cool off. There is also a pavilion to train under in case of rain.

It would be crazy to miss out on this event!
