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.
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!
I learned a lot through today's class. Indeed, Joshua has a vast knowledge of business English, it helps me a lot improving my social skills as well as presenting before a large audience.
