Our Instructors


Sensei George Koch

George Koch began his aikido practice in 1977 at Stanford University with Sensei Frank Doran, from whom he received his shodan, nidan, and sandan promotions. For a decade, George trained primarily at Doran Sensei’s Aikido West dojo while enjoying the diverse instruction of other Bay Area aikido teachers.

He feels fortunate to have attended seminars with Aikido Founder Morihei Ueshiba’s son, Kisshomaru Ueshiba, and primary students including Saotome Sensei, Saito Sensei, Yamada Sensei, Anno Sensei, and Kato Sensei, among others.  In the late 80s and early 90s, George taught aikido at UC Davis.  Upon moving to Flagstaff in 1994, he joined Bob Frumhoff and Trent Boudreaux as instructors at Aikido of Flagstaff and became a member of Aikido Schools of Ueshiba (ASU) under Mitsugi Saotome Sensei. 

His current major influences in Aikido are ASU Shihan Hiroshi Ikeda Sensei and Saotome Sensei as well as Suginami Aikido Shihan Hiroshi Kato Sensei.  George enjoys vigorous practice based on aikido principles of connection, timing, and movement.  He values the influence of aikido practice in his daily life and his close friendships within the aikido community.    



Trent began his training in the martial art of Okinawan Karate in 1974 at the age of six.

Since then he has trained in a variety of martial arts such as:  Tai Chi, Kung Fu, Karate, Judo, and others.  He began training in Aikido in New Orleans, Louisiana, at the age of 18 under Saul Smithson Sensei, 7th Dan. Sensei Smithson’s teachers were Koichi Tohei and Isao Takahashi. 

In 1989 Trent moved to Flagstaff Arizona, where he joined his sensei, Saul Smithson, in opening a dojo.  Within that time, Trent was ranked by Shihan Smithson as a San Dan.  Shortly after moving to Flagstaff, he met Bob Frumhoff Sensei (Go Dan) and joined his dojo as an instructor because Saul Smithson Sensei had retired from the Flagstaff dojo.  Since joining the Flagstaff dojo with Frumhoff Sensei, Trent has traveled all over the United States to train with various senior instructors in order to deepen his understanding of Aikido. 

Trent has also trained at Hombu Dojo in Japan and has had the privilege of briefly attending classes taught by Aikido Founder’s (Ueshiba, Morihei) son Ueshiba, Kishamaru.  Trent currently teaches at the Aikido of Flagstaff dojo and trains regularly with the larger Aikido community of Arizona Aikido.  His current major influences in Aikido are:  Shihan Hiroshi Ikeda, Shihan Mitsugi Saotome, Shihan Kenji Ushiro, Shihan Christian Tissier and the teaching staff of Aikido of Flagstaff.
