I teach basics as well as intermediate and advanced levels which suites different possible goals: studying in Russia, communicating with Russian-speaking friends or just a tourist visit to Russia. At this moment I don't offer any lessons in professional fields of using Russian, but the courses of Russian for lawyers and Russian for artists/art-collectors/art-students can be discussed as I have personal expertise in these fields.
Be ready that we'll be mostly speaking Russian, even if your level is not too advanced yet (this is called 'deep immersion method'). And be ready that we'll use a lot of language and word games, I do believe that this is easiest way to memorize things and not get bored by it.
Besides, I work as a translator of computer games and I also take part in Duolinguo Russian team. If you are interested in my way of teaching — feel free to contact me any time.
