About Jits 56

Jits56 is dedicated to bringing the art and discipline of Brazilian Jiu-Jitsu and self-defense to the Powell, Lewis Center, Dublin, and Worthington areas of Central Ohio. Our mission is to create an inclusive environment where both seasoned practitioners and weekend enthusiasts are embraced as equals. Our curriculum is meticulously designed to enhance students' skills through a deep understanding of position, leverage, and technique. As an affiliate under Deon Thompson of Ohio Brasa, Jits56 proudly welcomes adults of all skill levels to join our community. The gym was founded in 2020 by Justin Kennedy, Rob McKeeman, and Mike Zimcosky, each bringing unique expertise and passion to the table. Rob, who previously owned a gym in 2012, met Justin during that time, sparking the idea of starting this Brazilian Jiu-Jitsu gym along with Mike. Together, they partnered with Deon Thompson from Toledo, OH, to bring their vision to life. Justin Kennedy, a black belt, serves as the head instructor, bringing his extensive knowledge and experience to lead the training. Rob McKeeman is responsible for running the defensive programs, drawing on his expertise in Krav Maga. Mike Zimcosky, a purple belt in Brazilian Jiu-Jitsu under Justin, has been trained in self-defense by Rob for over a decade, contributing to the well-rounded instruction offered at Jits56. We are committed to fostering a supportive community that encourages growth, resilience, and camaraderie among our members.
