I have known Irving for nearly 2 years now. He is dedicated, professional and puts a lot of energy and his sense of humour into his classes. He is also clear, patient and knowledgeable! I highly recommend Irving because we have worked together to improve my English for my job, and I have been able to move to a new position in my company thanks to his classes.
