Bartosz is the best teacher I've had so far on iTalki. He is very smart and disciplined. He was correcting me and translating me unknown words in a way that in one month I made incredible progress, reaching the desired level in time. He can adjust to the method that suits you best and is able to hold interesting conversations, as he knows a lot. Hands down the best one for Polish in any case.

Prawdziwy profesjonalista, Bartosz nigdy się nie spóźnia i zawsze ma o czym porozmawiać. Już po pierwszych zajęciach przypomniałam sobie, że mam syna.

Gorąco polecam konwersacje z Bartoszem! Rozmowa płynie bardzo naturalnie, a tematy zawsze super ciekawe. Idealny wybór, jeśli chcesz zacząć swobodnie mówić.

I have been studying with Bartosz for a while. He is kind and patient. He is thorough. I feel I have improved under his tutelage! Highly recommended!

Really great conversation!

Bartosz is very knowledgeable about many topics, including American politics, international relations, and comparative religion. That makes it easy to talk about your interests and particular needs with him in English. He is a sympathetic and patient man. I will certainly take a lesson with him again, as I have many times in the past.
