Serge is great. He is amazing at every language he speaks and a great tutor to talk to. He makes his lessons entertaining while still very educational and he is a great person to be able to talk to and doesn’t keep it too formal or informal. Overall great tutor thoroughly recommend

I’ve been learning Russian exclusively with Sergei on italki (almost 50 lessons) and I can say that he is everything I expect from a professional teacher.
Very pedagogical, forward moving, a great patience and at the same time very understanding and flexible.
He has helped me to progress my Russian talking, writing and understanding by a huge amount.
Thanks for all the lessons Sergei! 🤩

Sergey is my first teacher here on itaki and he's been excellent so far! I really feel like I'm learning the language properly. He provides good study materials as well as new words and concepts not mentioned in the texts. Plus he is patient and learning with him is always pleasant.
