INSTRUCTORS
Hapkido West’s core instructors possess over 180 years of collective experience in the martial arts. While many of us come from strong, tradition-oriented martial arts backgrounds, we nonetheless share a modern point of view, characterized by an openness to new ideas, a willingness to innovate, and the recognition that all martial artists are brothers and sisters, irrespective of style or beliefs. Brief biographical information on our instructors is given below.
