SPECIALIZED LANGUAGE EXCHANGE

Hello,
My name is Susana and I work as a part-time English teacher in a private school. Although I got my Certificate of Proficiency last year and my grammar and reading skills are up to the level, I feel I need to reinforce my speaking and I would also  like to broaden up my vocabulary. Hence I am looking for a teacher or a native speaker with a high awareness of the language to help me improve my actual use of English and build my confidence to teach the language.
Since I am also a philologist and a qualified Spanish teacher, I was thinking of the possibility of offering a knowledge exchange, as I imagine there might be native English speakers living in Madrid who are past the formal learning stage but still feel they want to get specialised help to improve their command of Spanish. If that is the case, I will be pleased to help you with whatever grammar doubts and provide you with material to work on those language areas you would like to focus on. I am a very curious and open minded person, with interests ranging from current affairs, art or history to self-development, mindfulness or ecology. At the moment I am widely available in the mornings (Mo-Wed) but I would be also open to meet in the evenings or even during the weekends. Please drop me an e-mail if you're interested.
