他是一个很亲切很可爱的人，如果想出国留学的国人，很推介这个老师

Hard working, friendly, patient; practicing a lot during the classes, making me remember the patterns eventually. Thanks a lot, John!

very nice

The best teacher ! The conversation class is very good

John is kind, friendly, patient, brilliant, and incredibly talented. He's always encouraging me and making me feel more confident. I could go on for another three hours just talking about how great he is, and I still wouldn't be done lol. But all in all, he's simply the best!

Good teacher! I will get a lesson again:)👍🏼👍🏼👍🏼
