Being born and bred in France, and then living all my adult life in London, I still carry a French accent, mannerisms and gestures when I speak.  I can help students to go through the textbooks, bringing additional props, pictures and material into the tuition; I can help them to express themselves with clarity, without fear and without translating in their head from one language to the next, to learn nuances in the meaning of words and best ways of communicating as if they were living in the country.
