Teaching English to Speakers of other Languages

In Argentina, I worked with students of different ages and levels and different backgrounds, but most of them were Argentinian. I worked 9 years in an English school and I was in charged of more than 7 courses and also I prepared and examined Cambridge exams.
When I moved to Tulum I homechooled 5 Mexican kids, then I tutored for a year and a half an American boy. After that I was a teacher of English in a secondary school. The students were of different nationalities.
Now I am teaching English and Spanish to different people from all around the world.
