Our senior instructors trained with Saito Sensei in Iwama, Japan, and at his California seminars starting in the 70s and continuing through the 80s and 90s.  This includes a number of classes he taught at our dojo in Oakland.  Together with other students, they created a space in California for Aikido as taught by Saito Sensei.  Our junior instructors are all 3rd Dan or above and have trained extensively in Aikido. 
​Aikido Institute is a non-profit. All of our instructors volunteer to teach Aikido at our dojo. Together, they offer a wealth of knowledge and experience on the mat, and are valuable dojo resources.
​
Kim Peuser, 7th Dan, Shihan,
is our dojo's highest ranking member and serves our Supervising Instructor.  He is a founding member of the Takemusu Aikido Association and  serves on its Board of Directors and Ranking Committee, and is also Supervising Instructor for several dojos around the US in addition to ours, including Mendocino Aikido in Mendocino, CA, where he retired to in 2017.

Kim Sensei began studying Aikido in 1974 at our dojo which was on College Avenue in Oakland at the time.  In 1976 he became a live-in student at the dojo, and in 1977 went to Japan for the first time, living at the Iwama Dojo and training under the late Saito Morihiro Shihan who promoted him to Shodan.  He returned to Iwama 4 years later, continuing to study with Saito Sensei while living outside the dojo.  In 1987 he became Chief Instructor of the Oakland Dojo; he turned the role over to Hoa Newens Sensei several years later, but took over again in 2001 and stayed as Chief Instructor until 2017.

Kim Sensei has taught seminars in California, New Mexico, Arizona, Texas, and New York as well as in Italy. In January 2020 Aikido World Headquarters in Tokyo awarded him the title “Shihan”.

Stephen Kilmer Sensei, 5th Dan,
​is a senior instructor and previous Dojo-cho (2008 - 2017).  He began studying Aikido at the Aikido Institute in 1981.  As he puts it:

​I have found that Aikido changes the more I study.   I'm sure this is a reflection of how I have changed and of the increasingly more detailed things my teachers have shown me about Aikido the longer I've trained. 

​Dave Lewin, 4th Dan, is Co-Dojo-Cho with Deborah Sensei, and assists her in managing the dojo.  He excels at helping new students make progress in their practice.
