Teacher Charles' knowledge is excellent and strong in many fields; so, in this sense, the tutoring with him, is very productive in many topics. In my specific case, he helped me giving me a new and different approach to Business English, and also to handle in a better way the anxieties and insecurities in business presentations, and corporate meetings. I highly recommend teacher Charles!
He always tries to understand my business situation and help me with how to do. I am very busy and request to change the date for the lesson, he is very flexible to do so. When I feel tired with the ways of lessons, he changes the text books/materials/topics in order for me to dedicate myself to study English. He is a very knowledgeable tutor to teach the native American English accent to non native English speakers.
Jeremy recommended me to record my own voice. (I did not like that.) However ,I can recognize that I have improved when I listen to my voice which was recorded before. In addition, Jeremy knows business well. He teaches me business English such as writing a business e-mail and making a presentation. I feel confident when I speak English in my office recently. Jeremy teaches me not only English but also communication ability. Thank you, Jeremy!
