Will Yturriaga began his martial arts training in 1987 at Sensei Richard Kim's Dai Nippon Butoku Kai International Organization. There, he extensively trained in full-contact Shorinji-Ryu Karate, Bagua Zhang, and meditation. His studies eventually took him to Sifu John Kang’s East West Wing Chun Kung Fu school in San Francisco's Chinatown, where he later became the main instructor. Sensei Will taught the class for over six years, focusing on training a core group of instructors. In 2014, he founded The Martial Arts Academy of Marin, where he currently teaches Full Contact Shōrinji Ryū Karate. His teaching approach blends adaptability and modern innovation while maintaining a deep respect for tradition.
