Hey Luke
I don't know who you would call BJ's "instructor"now, but he was previously with Ralph Gracie at his Mt. View academy and now in Vegas as a member of team "Novo Unio" or "New Union".
As for Matt Serra, he is a blackbelt under Renzo Gracie in New York however he now has his own academy in Long Island. He still trains with Renzo daily from what I understand.
