Aikido Center founder, Rodney Grantham, began his martial arts training in Japan in 1950. He earned his first degree black belt in Judo there before returning to the U.S. where he rose the rank of 3rd Dan. He was first exposed to Aikido when he took ukemi for the legendary Koichi Tohei and began making trips to New York to study under Yoshimitsu Yamada Shihan. Grantham Sensei soon began offering Aikido classes at his “Black Belt School of Judo”. These classes were the foundation of what became the Aikido Center of Atlanta. After many years of practice, he became one of the first non-Japanese to be awarded the rank of 6th Dan. Grantham Sensei was a pioneer in introducing traditional Japanese martial arts to the Southeast. In 1989, after many years of teaching and shepherding the growth of Aikido throughout the region, Grantham Sensei retired to the mountains of North Carolina with his wife Janet. Grantham Sensei passed away in 2008, but his legacy is carried into the future by the hundreds of Aikidoka he influenced throughout his life as a Martial Arts pioneer.


George Kennedy, 7th Dan, Shihan, began his training in 1972 at the Aikido Center of Atlanta and became Chief Instructor and Dojo-cho in 1989.

Kennedy Shihan has also developed Aikido-based defensive tactics courses for Law Enforcement and has been a contributing member of the Georgia Association of Defensive Tactics Instructors. These activities reflect his belief that Aikido is both an effective method of self defense and a path of peace and reconciliation. He has served on the Board of Directors of the USAF since it's inception in 2007. He is chair of the Dispute Resolution Committee and is the main author of the USAF Student Guide.
