He grew up in Kona Hawaii and served six years in the U.S. Coast Guard. He primarily wrestled in high school and in the military. He dabbled in different martial arts throughout the years. After the military, while working in Detroit he was introduced to and trained in the Genbukan organization of KoRyu Budo. At this point his passion for KoRyu styles of Japanese martial arts are what he wanted to continue to study. He eventually settled in the Miami Valley where my real journey in martial arts began with the Gi Yu Dojo. In January of 2019 he began pursuing his passion under Sensei Sukh Sandhu. “The study of martial arts, I believe, is about the personal pursuit to become the best person you can be. Not just in a physical way but to also strengthen characteristics that show good morals and values.”
