That is correct. Sean Askew has been around for awhile along with Jeff Ochester whose Dayton Bujinkan is now an affiliate of Sean Askew's BKR organization.
There is another Bujinkan instructor in Dayton, Jerry Shadoan of Shadow & Light Academy www.shadowandlightacademy.com
I don't know what is so attracting about Dayton but I'm NOT complaining since the arrival of Sean will mean a bit more variety in teachers for me
