Hello. My name is Renshi Michael Pinelli, and I am the owner, founder and chief instructor of East Coast Karate.

We pride ourselves on teaching the highest quality martial arts, character development and moral integrity. We welcome children from the age of four, up to adults of any age. We do not tolerate nor welcome individuals with negative intentions. Our “ego-free” team atmosphere is contagious and one-of-a-kind – just ask any of our students or parents of the children who train with us.

Theresa A.

“Strong dedication to the art and to his students. Constantly learning and implementing new training exercise to better apply your skill to real life scenarios. A fun environment to learn, but never a place to take lightly. You will be worked and that’s just the start. Mike is the type of teacher I am proud to have trained with over many years and I cannot recommend him highly enough.”


“Mr. Mike is one of the best people I know. Runs the place like it should be! Got my black belt here and it was TRULY an accomplishment being that I had to earn it and it was not just handed to me. Best place for karate or kickboxing or anything really!!! Five stars!!”
