Robert Nadeau Shihan began his martial arts training in the 1950's, studying judo, karate, and defensive tactics as a police officer in Redwood City, Ca. In the 1960's he left police work, traveling to Japan to study with Aikido founder Morihei Ueshiba.
Over several years he received personal guidance from O' Sensei in the philisophical and energy aspects of Aikido. Throughout the 1970's and 1980's his work brought Aikido concepts into the fields of psychology, body work, and the healing arts.
Nadeau Shihan has been a major influence in the development of Aikido in the United States and on many of today's Aikido instructors. His approach to martial arts training transcends technique to give students something applicable to life and an aid to self transformation.
Nadeau Shihan co-founded the Aikido Association of Northern California (AANC), and The California Aikido Association (CAA), which is affiliated with Hombu Dojo, World Aikido Headquarters. He teaches at City Aikido of San Francisco and at Aikido of Mountain View. He also teaches seminars around the world.
