In 2006, Hayes's name was removed from the display of active Bujinkan teachers, ending his official role within that organization. That his name plank was removed from the Bujinkan Honbu wall has been documented by both parties. However, the specifics regarding the motivation for the removal are in dispute. Some suggest Hayes was expelled from the organization. Hayes explains that he simply no longer participates as an active Bujinkan instructor. To-Shin Do is taught through his SKH (Stephen K. Hayes) Quest locations. The SKH Quest network now spans 31 schools across North America, Europe, Australia and Africa.
