English/American Schools Alphaville (São Paulo)

Hi,
my nae is elena and will be moving with my family to SP end of Feb Protected content . We are currently looking for an English speaking school, possibly with many international kids and with English/american Native teachers.
I have looked at tip toe and the INtl school of Alphaville as well as Maple bear...The limits of these schools is that they are not FULLY English and teachers are not native speakers. Do you have any recommendations'? Suggestions?
Thank you for your help
