I received the ranking of Shodan on 7-27-1980, Nidan on 7-30-1983 and around 1989, I moved to San Jose, California for job opportunities and started training with Professor Sig Kufferath / Professor Richard Bunch in Mountain View California. I continued being ranked by the Chow-Hoon organization and J.A., receiving my Sandan on 1-27-1990 and received Yodan on 12-21-2010 and Godan on 9-7-2018. Presently, I continue to train and to be one of the instructors at Nikko Jujitsu School.
