My kids improve their Cantonese a lot with Zack.

It’s rare to find a native speaker so attuned to (and interested in) the intricacies of their own language. I feel like I can come to Zack with any question (whether it’s about proper usage of a new word or grammatical constructions that my brain has a hard time processing) and his responses are always clear, thoughtful, engaging, enlightening, and motivating. If needed, he will take the time outside of class to properly address any questions I have. He pushes himself to fully understand any linguistic phenomena I express interest in so that he can teach them to me as clearly as possible. He is one of the most talented, dedicated teachers I have ever had both in and outside of language learning—and he is certainly one of the kindest. I also really appreciate his infectious sense of humor. I really can’t recommend Zack highly enough. I'm looking forward to our next lesson (as always)!

Zack is really knowledgeable on Cantonese and even English linguistics. His lessons are very structured and I feel like I learn a lot in every lesson. Would recommend taking lessons with him!

Really enjoyable lessons! Zack is always well prepared and his lessons are relaxed yet well structured, with a sound grounding in grammar and pronunciation. I really like the pace of progress and review, in our lessons.

Best italki lesson I've ever had. Zack understood my exact needs and used my strengths to help me confront Cantonese, which I've feared all my life. Looking forward to the next ones!

Great lessons as usual, and Zack is the best Cantonese teacher we've ever had!
