I don't live in Boston (actually, my son dances in the Western Region also). Seamus Conolly would probably know, although I think there are more direct ways to get the info you need.
I would ask her current/former teacher at the Kennelly School for a recommendation, . There are a lot of schools in the Boston area and all the TCRGs have a book which lists the dance schools/teachers around the world.
I have a few other ideas- feel free to contact me directly at email@example.com
