Instructors
Our Team
Below are the volunteer instructors of the Dayton Bujinkan Dojo. Many of the senior instructors have been training since the early 1990’s. All of the staff members have professional careers outside of the dojo (or are retired!) and volunteer their time to teach. This helps build a strong Bujinkan community without the burden of making an income from teaching. Each instructor teaches with their own personal experiences intertwined, allowing students to see natural adaption and unique approaches to Bujinkan Budo Taijutsu. Below provides a brief introduction of the Dayton Bujinkan Dojo instructors.
