Anyone know who these people are?

[Morgan]

I just got a flier advertising a mixed art summer camp with 10 instructors.
Of particular interest to me are the following names in alpha order and as
listed in the promo materials:

Master Roger Agbulos
Punong Guro Steven K. Dowd
Professor Sultan Uddin

Any information availible on these guys?
