John Mazza Sensei (Headmaster / Kō-chō)
Mazza-Sensei has had over 50 years experience in the study, practice and teaching of the Martial Way. He began his training in Korea in 1964 studying the art of Judo. Upon his return to the United States, he began his study of Oriental Philosophy and Meditation. Believing that the only true path to self-understanding is through disciplined practice and the Martial Way, he immersed himself in the study and practice of various arts.
Mazza-Sensei has studied various styles of Karate and Kung Fu. Feeling that there should be more to the Arts than kicking and punching, he embarked upon the study of Aikido. It was through this study that he gained a deep understanding of the Martial Way. At this time, he began the study of Zen and came to realize that all practice is truly one. The purpose of all training is the development of the individual.
Mazza-Sensei currently holds the rank of Rokudan in Aikido, issued by Aikido World H.Q. in Tokyo, Japan. He serves as Headmaster (Kō-chō) of the dojo.

In recent years he was an occasional visitor at the Fudoshin Dojo of Sensei Václav Kubát in Prague, Czech Republic (affiliated with Shihan Masatomi Ikeda). He continues to train under the supervision of Sensei John Mazza. Bina-Sensei holds the rank of Yondan and the title of Shidōin. He serves as faculty advisor and chief instructor of the dojo.
