It was one of the best lessons that I've ever taken. It will take a long time to reach fairly advanced and proficiency level. But it's worth it to try! I look forward to taking another his lesson very soon. Thank you, David.

It was one of the greatest lessons I've ever had. Thank you, David, for your professionalism and such an attentive approach!

Great lesson again! Thank you so much , David!

Thank you for the corrections for my resume. I really appreciate the work you have done for me. I will definitely come back to take another class in the future. (I took a course 'Proofreading -learn to write like a native.')

Another good lesson with David, very complete with vocabulary, pronunciation and lots of advice 🙂

David is well prepared, patient, and helpful. The course materials are interesting and inspiring! David is a good teacher!!
