  • Master Evan Hitchcock began his hapkido journey in 1985, but his fascination with martial arts started a decade earlier while in grade school after purchasing a pair of junior karate and judo books at a schoolbook fair. Under the tutelage of Great Grand Master Chong S. Kim, Master Hitchcock honed his technical, physical, and mental skills necessary to master Hapkido, the “Art of Coordinated Power” and its three primary principles of water, circle, and harmony.  While developing his expertise in Hapkido, Master Hitchcock also acquired life-long skills, such as respect for others, honor, self-confidence, and mental toughness. As a master instructor, he is committed to developing these same skills in his students. Moreover, he willingly shares his technical knowledge and passion of martial arts with others.

    In the early years of his training, Master Hitchcock attended California State University of Long Beach, where he earned a Bachelor of Arts degree in journalism with a minor in marketing; the same year he earned his 1st Degree Black Belt in Hapkido. A few years after college, he married his wife of 30 + years and raised two children just a few miles from where he took his first hapkido lesson at the original studio in Alhambra. Today, he is a senior executive in the credit union industry.

    During his hapkido career, Master Hitchcock opened two studios – one as a manager and one as an owner – and taught countless classes at the various studios within the Jang Mu Won Hapkido organization. As a lifelong hapkido practitioner, he believes that “work” is never done and lives by the personal philosophy of “train when you teach and teach when you train.”

  • Master Ng has been a practitioner of Hapkido since 1997. He started his training under the tutelage of Great Grandmaster Kim at the Alhambra studio. With many fond memories growing up as a part of the Kim’s Hapkido family, Hapkido has always been the best time of the week as it was quality time to train our craft and to live and breathe our art.

    Overcoming physical challenges opened his mind for being able to achieve anything with enough practice and dedication. As a college educator outside of Hapkido, Master Ng still thinks of all the lessons and ways of teaching that have been developed at the studio. As with any joint lock or throw, we must follow the flow of energy and move to direct our opponents as we react to the situation. If there is resistance, we can pivot around it and confidently adjust. In a conversation with Grandmaster Kim of how there are no bad students, as we as teachers need to evolve to better instruct from a different view or perspective if needed. This has always resonated with him on and off the mat.

    Master Ng wishes to share with the students of Jang Mu Won Hapkido so that they too are inspired to return to Hapkido to fulfill their lives as a martial artist.

  • Master Bouchereau received his first degree certificate in Hapkido in 1988 and received his sixth degree promotion to the Master level in 2008. He has been studying Jang Mu Won Hapkido exclusively under Grandmaster Kim since 1985 and has been teaching for over 29 years at the Alhambra Headquarters.

    Master Bouchereau is also a doctor of Chiropractic. He has been practicing in the San Gabriel Valley since 1980. His office is located at 6456 York Blvd, Highland Park, CA. Master Bouchereau is the official chiropractor for the Jang Mu Won Hapkido Association. He serves on the judging committee for the black belt testing.

    Master Bouchereau has a private pilot's license and frequently flies his Cessna T210 to Mexico on medical missions with other doctors and dentists to provide free health care to the native populations.

  • Master Asbury began his Hapkido training in the early 2000s at the South Pasadena school with Mr Kim (now Grand Master Kim). While he came to martial arts in his mid-30s, carrying the usual growing limitations of age, he dived in and was soon taking four or five classes a week.

    As time passed Mr Asbury began to leverage his experience teaching in the other settings to assist his instructors. Starting with beginner classes, then sparring classes and ultimately working through the curriculum, Master Asbury now spends most of his time working with black belt students and candidates. In the last twenty years he has had the pleasure of working with hundreds of Jang Mu Won belt candidates, and assisted many higher degree candidates successfully prepare for their tests.

    Because he started at a later age than most martial arts students, Master Asbury has a different perspective on the various areas and techniques taught in Jang Mu Won Hapkido. While punching, twisting and throwing are all within reach, double jump kicks were, and still are, a bit out of range. Physical constraints have motivated him to learn from students and other instructors how to teach the things that he can't do and translate techniques to students based on their own limitations, including older students and students with physical constraints.

    In his day job, Dr. Asbury is a software developer and manager with a PhD in Nuclear Engineering and experience working at a range of companies including Google, Honey and NeXT. Currently Dr. Asbury is working with Striveworks to bring Machine Learning to the battlefield through contracts with the US military.

    Master Asbury can usually be found teaching the blackbelt classes at the South Pasadena and Alhambra studios. He has been known to show up at the Yucaipa studio now and then to visit Mr Castle who was his partner for many tests and has been an integral part of his Hapkido journey.
