Due to him being an Active-Duty Veteran with the United States Coast Guard, there have been many times where he was unable to train.


Upon stationing in the National Capital Region, he sought out a new dojo and found us.


He is recently passed his first degree black belt test in April 2023.

He is currently an assistant instructor with Yamagiri Dojo (NinVolution).

He has also been relocated out to the West Coast for the foreseeable future but will drop by the school when possible.

Sensei Anthony

Assistant Instructor


Sensei Anthony started Martial Arts back in the 80's with Karate. It was a fun first step into the world of martial arts for him.


When he was older he began studying Jujutsu, which has strong connections to how he now practices in Ninjutsu, however, due to moving overseas for work he had take a break from his Jujutsu training.

Fast forward to today, He has been studying Ninjutsu, for over three years achieving his black belt in March of 2023. He has enjoyed training and learning from the Instructors in the Nova area continuing his martial arts journey.

Ninpo is a fascinating and very varied martial art, those who have the dedication to master it are in for a very rewarding journey where you will learn a variety of new skills.

Ninjutsu is an ancient Japanese martial art that has been practiced for more than 1300 years (over a millennium). The art is popular around the world with masters hailing from Japan, United States, Brazil, Canada, Israel, United Kingdom and others. Ninjutsu is based on techniques popularized and utilized by the Ninja and the Samurai class in Feudal Japan, used in warfare. The techniques were previously only passed on through demonstration and word of mouth transmission.

NinVolution is part of a group of schools along the east coast of the U.S. currently in Virginia, Maryland, Delaware and Florida. Sensei Joshua Friedland has been training in Ninjutsu for six years with over a decade of martial arts experience between Karate, Tang Soo Do, Kung Fu, Taekwondo, Ninpo, as well as the Modern Army Combatives Program (MACP) from the United States Army.
