Frank has been the best teacher that I have encountered in the past few years. Very professional, speaks perfect English which is important to explain complex advanced terms and just a very dedicated teacher in general. Following the first class, I booked immediately another 20 classes with him. For reference, I have already passed the HSK 6 exam and have been studying Chinese for over 5 years.

Frank is an excellent and well prepared teacher who is able to teach highly specialised an niche topics. He usually sends me a short vocabulary list in advance. In class, we discuss a topic in detail. I am very satisfied and will continue to take Frank's class.

Frank used the white board to go through a grammar point then we did it together on a doc he sent me. Really great. I’m going to try to keep weekend meetings.

very prepared! i told him a couple days ago i was going to attend yiwu fair in china, and todays lesson he suprised me with a very great indepth analysis of what to expect! thank you and great as always!

Honestly, although Mandarin is new to me, and the phonology and tones are a bit alien to me I find that Professor Frank is good at making me recognize and produce the correct sounds (with guidance of course). He also speaks English and Spanish very well which gives him a lot of references when it’s time to explain concepts. If you are a total beginner to Mandarin, please book this teacher.

I highly recommend learning the very basics of pronunciation with his guidance. It's tough but fun.( me as a Spanish native Speaker knowing some English).
