About Our Instructors

Hanshi Kevin Huunjin Cullen

Kaicho/Headmaster

The Academy exists under the leadership of Hanshi Kevin "Huunjin" Cullen. Cullen has been consistenly training in Goju since 1973 and has achieved the rank of Ju-Dan, Hanshi, and Soke (via the World Head of Family Sokeship council) Unlike so many others, he has not paid for his rank, hanshi or soke certificates but earned them in the old ways. In addition, his three bachelor and two master degrees were earned via some 13 years of academia at the University of Findlay and are verified by the Ohio Board of Regents. Beware those martial artists who claim a Ph.D in Asian Studies or Martial Arts, many were bought and paid for from Mr Thomas in Indiana. The US Attorney General has since enforced a "cease and desist" on such activities. 

Hanshi Cullen's students have won the US Open, NBL & ISKA national titles, Canadian National Goju Championships, Gold Medals at the Arnold Sports Festival and have fought in various UFC events. To read more, scroll down to the bottom of the page. *
