Teacher Costello is one of the best teacher I already saw. His american English pronunciation is perfect and clear. He is a highly recommended teacher.

I thought that all teachers have same lesson manual.But this lesson was different as usual. If the students is young,asking your age is OK,I think.But me・・・I don't want to ask my age at the very beginning of the lesson. my family and my real name also. Because It was first time that I met.
