''Marianne Graff showed herself to be an excellent teacher and content designer when she worked for us at the Academia de Artes y Lenguas, Arica Chile from January 2010 to March 2010. She was in charge of organizing, designing and teaching the whole of the summer school (Southern Hemisphere) with great success. She was well loved by her students and appreciated by all the staff. We were sad to see her go.’’
- Emily Walker, co-owner of Academia des Artes y Lenguas , Arica, Chile
Marianne Graff is one of the best teachers that I have ever met, and by far the best one in English. I met her when a took an English course from September 2011 to October 2011 (100 hours course) in the context of a scholarships programme given by CORFO at the American Chilean Institute in Valparaiso, Chile. Before the course started I took the TOEIC exam and a got six hundred points, then I took it again at the end of the course and I got more than eight hundred points, this was thanks to my effort, because I really wanted to improve my english, but especially thanks to Marianne, because she is an amazing teacher, I always understood every single thing, she kept me motivated during the entire course and she always was available for any question that I had. She is a great teacher!
