English classes with native teacher of 16 years experience

My name is Marc .
I'm from New York City .
I am a TEFL Professional Development Institute certified English teacher
I have been teaching English for 16 years in Madrid.
I teach one-on-one and business classes online (via Teams , Skype and Zoom) and have extensive experience in business English.
My goal and priority, in addition to helping to solve any pending grammatical problems, is to design classes that correspond above all to the professional life of my students.
When appropriate, I also try to teach what I consider to be the important things in everyday life in English, such as idioms and common expressions, and to some extent, where necessary, fill in perhaps some of the cultural differences necessary to help always avoid misunderstandings with the aim that my students look good when speaking.
I have taught at companies such as Maersk, Orange, El Corte Inglés, Siemens, Repsol, BBVA, Banco Santander, Renault, BBVA Fundacíon, Banco UBS, Unibail Rodamco, Prosegur, La Mutua Madrileña and at the Banco de España.
I have worked with companies such as Astex, Vaughan Systems, Auler and Idiomas C.E.E ..
I correct all the spoken errors in a very pleasant and dynamic way that helps the students when speaking.
I really enjoy helping my students achieve their English goals and work diligently to achieve those goals.
I would be delighted to work with you.
Best regards
Marc
