"An individual commitment to a group effort, that is what makes a team work, a company work, a society work, a civilization work."

Our philosophy:

to prepare a student for life.


I asked around about Jiu Jitsu instruction and others that are long time veterans

of the fight world recommended Erico with enthusiasm.


My teenage sons are new to the sport and have been going here since the opening. They speak highly of Erico, his skill, teaching style, and attitude.

They go to extra classes every chance they get, which says it all for me.
