I’m an English, first language speaker and my native language, which I later learned was Persian. I have a MA and BA in English philology and literature and am a Ph.D. candidate in comparative, contemporary literature. I also have a certificate in TTC and Journalism. I have years of experience in teaching languages in institutions and as a freelance tutor, all levels and all ages!
