I've been working with Jack to improve my accent. He's patient, attentive, and gives very clear feedback on pronunciation. He identifies specific patterns to work on and explains them in a way that's easy to understand and practice. Highly recommend him if you're serious about improving your accent!

和Jack老师学习五年了，小宝宝变成了大宝宝

Great lesson with Jack. Clear explanations, very patient, and easy to learn from. Highly recommended.

It has been 5 years since we learned with Jack

I've been learning with Jack for more than a year and have made significant progress beyond my expectations! Jack is always supportive and kind. He explains clearly and effectively. He takes time to prepare interesting materials and topics for us to discuss in class. He also takes detailed notes during class, and assigns suitable homework as needed. With his help, learning languages has become more enjoyable and more productive. I really appreciate all the time and effort he puts in. He is an excellent teacher whom I would highly recommend!
