Native English teacher

I am originally from the US with significant experience teaching English to foreigners. I spent 3 years as a teacher in Argentina where I taught local employees for a multinational firm. I ran large classes of 25 students and also private sessions. I am bilingual (English/Spanish) so I understand the process of learning a language and proven approaches to learn efficiently. I am now living in Germany and hoping to use my experience to help people achieve their English goals.
