I've heard really good things about Winged Wonder. It's in the Makati area, so you might want to check them out. I'll put a link below. If you're interested to know, I've heard that the staff is very warm and welcoming. Not to mention that they work with pretty much every age group you can think of! http://www.wingedwonder.org/
