Sensei David Hermann started his journey in the martial arts at age 5 and eventually
learned about the art of Ninjutsu through Stephen Hayes “Ninja” book series
as a teenager. As there was no local Ninjutsu dojo at the time he followed a
path of studying many different martial arts until years later, as an adult, he
finally met Doshi Richard Van Donk, and Sensei Dena Johnson and Ephraim
Cheever. In 2022 he received his Shodan, then the following year his teaching
license. In 2024, he received his Nidan (2nd degree).
