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.

Who We Are

NinVolution is a company in name and mindset dedicated to promoting individual evolution based on Balance, Perseverance and Endurance. We teach leadership as well as situational awareness. We are a small veteran-owned business.

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 five years with a total of 9 years of martial arts experience between Tang Soo Do, Karate and hand to hand combat training from the United States Army. Sensei Friedland’s direct teacher is Sensei Omar Gilani of Yamajiro Ninja Academy in Vienna, Virginia. We are all students under Shihan Mark Bramble of Ninpo US (The Budo Center), who has been training in Ninjutsu for over 38 years.
