Working with David was just perfect! He had a great sense of humor and knew exactly how to work with us. At every session, not only did we learn English, but we also discussed a lot about Business and Psychology. David is a very open minded and well educated teacher, who really seems to enjoy and love what he is doing. I recommend him to everyone and every institution to work with him, due to his flexibility and willingness to teach so much more than just language. His focus is talking and expressing, with a little less focus on grammar, which is in my opinion really the best way to handle it, because we learn a lot more by talking than by learning. We all are very unhappy to see him leave and wish him all the best.
