You are a great teacher who can understand the difficulty in speaking English for non-English native speaker.Maybe your teaching method is useful for me from the first class.

老师很好，儿子很喜欢他

My english is poor,today is my first time study in here,Carl is very patient ,and his chinese is very good!And Carl has gave me some informathion,thanks a lot ,and I think I'll continue to learn from Carl

Carl老师会中文太厉害了

老师很好很亲和

Carl was kind enough to let me book a class with him so that he could teach me the ins and outs of starting a podcast. He was incredibly easy to communicate with prior to our lesson and he provided me with a lot of useful information. I can tell that he's an incredible teacher by the way he explains extremely complicated topics that I have no previous expertise or knowledge in. He gave very clear examples and even provided numerous visual aids to help me understand! I highly recommend Carl for any student looking to advance their foreign English skills, as well as English natives looking for an experienced mentor in the world of podcasting. Can't wait to speak with him again :)
