I would like to express my gratitude to Anna Viktorovna Kumko for the professionalism and patience she showed in working with my child. I came to her with a request to put the sound "Sh" and we had only 2 months of vacation time. In this short period of time, she managed to give the child not only a "Sh" but also all the other sounds that the son did not pronounce. Of course, we still have something to work on, but following the recommendations and materials that Anna Viktorovna provided us with, we will definitely learn! Thank you so much for the work you have done! We can definitely say that Anna Viktorovna is a professional in her field, classes with her are interesting for the child, and most importantly effective! To anyone who is looking for a specialist for their child, I recommend this wonderful speech therapist!
