Alex is a great teacher. If you are serious about learning Russian he is the one you need. I have taken many Russian courses over the past couple of years and none have helped as much as Alex's classes. The amount my Russian has improved (and continues to improve) shocks me sometimes. Seriously, if you have a passion or need to learn/improve your Russian then look no further. He is a great guy and a pleasure to converse with. I am grateful and proud to have him not only as my Russian teacher but also as a friend.

我喜欢这种上课的方式，在有限的时间内，老师讲力争让他讲的每一句话都让我明白，并且力争让我讲的每一句话都准确无误。 很好！ 希望老师不忘初心 ！~~~~

he is really the best there is. whenever I interview on Russian tv, the last question is "where did you learn Russian so well" and the answer is Sasha.

Alexander is a very good teacher. He makes you work quite hard, but his technique is very interesting and it is worth putting in the investment that he demands as you come through with a much better understanding of Russian grammar. He is friendly and professional and generous with his time.

He is literally the GOAT, the Lionel Messi, the Novak Djokovic, the Lebron james of teaching Russian. Anyone who does not take his class is missing out.

10/10 - patient, good materials, ability to make complex grammar accessible
