Need native English teacher for my 2 sons. (São Paulo)
My name is Evandro and I have worked for Bunge in NY for the last two years. My two sons have learned very good English during this period and now we're back to Sao Paulo. I'm really worried that they may lose their fluency and vocabulary over time.
So I'm looking for a teacher, preferably an native American. Do you render this kind of service or know someone you could recommend? Thank you.
