One on one Spanish classes by Bilingual Spanish teacher

I am a bilingual certified native Spanish teacher who focuses on conversation, not only on grammar (most of the people learn some Spanish, but they cannot really speak) 
My experience teaching Spanish: besides teaching Spanish in Barcelona for some years, in the past I worked in the USA (Boston) teaching Spanish for 5 years and I had the chance to work intensively with people from  different universities (Harvard, Boston College, MIT, etc) getting very good results. Therefore I have a great deal of experience working with English Speakers who want to learn Spanish.
My classes are one on one private classes, tailor-made lessons, very intensive and with a practical emphasis, diction and vocabulary skills within the cultural context of the language.
I use communicative method focus on task and Flipped classroom method among others. Additionally, I can teach late hours for busy people who work the whole day.
