I'm an English teacher with 20 years of experience, and I offer online EFL classes for foreign students and grammar lessons for natives. My YouTube channel (MrSkypelessons) has more than 2000 English lessons, which have been viewed more than 14 million times; I am the author of 4 English study guides, which are available as free PDF downloads in four of my courses. Having worked in schools, universities, and businesses all over Moscow, I am a competent Russian speaker, so I know the frustrations, the difficulties, and the joys of learning a foreign language. I have also worked for the Department of Education, preparing native English teachers for grammar in the classroom.
