Bom dia, dr. Luis, eu sou Maristela e falo sua língua, pois sou brasileira. Tenho mais de 30 anos de experiência dando aulas de inglês para adultos, mormente executivos e acadêmicos, inclusive preparação para o Toefl, em que me especializei em 1987. I took my Bachelor's degree in Languages (English/Portuguese) in 1983 from Faculdade Ibero-Americana de Letras e Ciências Humanas, which included teaching subjects, American, British, Portuguese, and Brazilian literature, and 5h30 hours of classes every day for 4 full years. In my senior year, I shifted to the night period because I got a job at JP Morgan, an American Investment bank, where I worked directly with Americans for 6 years. In this period I entered a very coveted postgrad Business Administration course and was promoted. However, I later decided to become an English teacher and my success was immediate, since my former colleagues asked me for classes and referred me to people at Citibank and I never needed to put an add until this crisis in Brazil 4-5 years ago. I adapt the classes to the needs of the student, which I detect in the initial 3 or 4 classes. I have already been teaching via Skype or cell phone. I can send you my diplomas and other info via chat. Estou disponível e adoro dar aulas. Moro num local sem ruídos e com boa conexão, o que otimiza o tempo e queria oferecer a primeira hora gratuita para você ver se eu sou a professora certa para você. Let's chat, shall we?
