Coaching and adviceBeen there, done that

From Rick: more than 25 years of ninja martial arts, taught around the world.

Students, in their own words

From students who trained with Rick over the years.

The training is very professional, complex, creative and you always learn something new. Rick Tew is kind and helping. He knows exactly how far he can push his students. The atmosphere during training is nice, positive and always with a sense of humor.
Sibel K.
Variety of the training: several self-defense techniques for real situations, sparring, grappling, weapons, stretching, etc. Specially appreciated, we could also choose areas we wanted to learn and practice.
Gabriela Z.
Rick Tew is the most dynamic teacher and person that I have had the pleasure to train with and learn from. Years later and I am still amazed how his lessons still enrich my life.
Seth T.
He is very intelligent, very funny, very cool, and very disciplined. This rare combination of attributes makes Rick a dynamo of a person and teacher.
Jamien O.
What I like the most is the variety of the system, which involves everyday life training with how to be healthy in mind, body, spirit and nutrition.
Kevin O.
Although the students may join here starting at ground zero, if they simply choose not to quit, not to give up on themselves, they will eventually get there.
