This is one event not to be missed! Bill has a vast aikido history and was an Aikido pioneer in USA. He has written two books on Aikido: The Spiritual Foundations of Aikido and Aikido and Words of Power.
He was a resident on Japan from 1970 to 1980 where he studied Aikido under Yamaguchi Seigo Shihan, at the same time as Takeda Shihan and various senior Japanese AKI Senseis. He established Shobu Aikido dojo in Boston (http://www.shobu.org), and he was the first teacher of senior AKI America Sensei's Jean Rene Leduc & Lia Suzuki.
