Master Kenji Campbell
Master Kenji Campbell began his martial arts journey in 2004 under the guidance of the late Master Lee Dong Pil, training with him until Master Lee’s passing in 2024. Over two decades, Master Kenji earned his 5th degree black belt in Moo Duk Kwan Taekwondo and built a reputation as a fierce and thoughtful competitor. He became an internationally-ranked sparring athlete until a series of reconstructive knee surgeries pushed him to retire from high-level competition. Never one to sit still, he shifted his focus to competitive grappling, MMA, and kickboxing at the renowned AMC Pankration, while also carving out a side path as both a competitor and commentator in the esports world.
Master Kenji began teaching in 2011, finding a deeper purpose in helping students grow both on and off the mats. His approach blends technical precision with a heavy emphasis on empathy, self-awareness, and the steady development of physical skill and personal character. He believes martial arts should be a grounding force, noting: “Martial arts is the best tool that can help prepare us for a world constantly lobbying for our attention. It arms us with discipline, perseverance and self-respect.” Through that philosophy, Master Kenji aims to shape students who are not only strong martial artists, but also strong in character.
