I’m a Trainer With a Passion for Quality

Thank you for visiting my Kaizen website. I’ve been actively teaching since I was 16. I’ve studied a wide array of styles and formerly held many ranks and titles. My experiences taught me Rank, Style, and Title had nothing to do with the quality of martial arts training so many people receive. I will NEVER sacrifice the quality of my training, in exchange for massive amounts of students. I teach martial arts out of a passion to share my knowledge with others and give them the quality they desire and deserve.

My training in France and Tahiti over the course of several years exposed me to an entirely new concept in martial arts. For me, there was no going back to any other method of training other than what I provide now. Rather than memorizing forms, competing for trophies, or bragging about titles… I inspire my students to discover their own signature style, to develop instinctive skills, and understand concept application rather than memorization. I provide a dynamic and motivating environment, while focusing on personal one-on-one attention for every student I train. My passion is martial arts and teaching, and my commitment is to my students and their families.
