“I used Kathy’s service to translate some materials for the Polish Embassy.
At all times she was courteous and very helpful. She even arranged for a courier to deliver my information.
I would definitely recommend her for her services.”
Sam L.

Kathy is highly professional in both the translating and interpreting services she provides for my company. For many years she has been reliable, knowledgeable and flexible in any matter referred to her. She helped me to build my business and I look forward to having her as an important business colleague for many years to come.”

I needed some legal documents translated from English to Polish. A friend recommended Polish Translation Service. I came into contact with Ms. Kasia Olszanowski a linguist for Polish Translation Service. I explained to Ms. Olszanowski what I needed done and in a professional manner executed my instructions without any issues. Thank You for a great experience“.
