About us

SINE QUA NON is a professional language service provider. We offer translation and interpreting services and also provide language courses. Our team consists mostly of graduates of the University of Warsaw's Institute of Applied Linguistics, where the leading language experts in Poland are educated. Many of our interpreters and translators also have an additional educational or professional background, primarily in law, economics and politics. Combining this linguistic and content-related expertise allows us to offer services of the highest quality.
We are proud to have worked for numerous prestigious clients such as the Polish Ministry of Foreign Affairs, the Polish Academy of Sciences, the University of Warsaw Faculty of Law, the Friedrich Ebert Foundation, as well as many others. We have also taken great pleasure in interpreting for high-profile politicians including the President of the European Parliament Martin Schulz, the leader of the Labour Party Ed Miliband, the Vice Chancellor of Germany Sigmar Gabriel, the German Federal Minister of Finance Peer Steinbrück, the Polish President Aleksander Kwaśniewski, the Polish Prime Minister Leszek Miller and the President of the National Bank of Poland Marek Belka.
Our unique services are ideal for anyone who needs to communicate a business message in a smooth and professional manner. We believe that by helping you expand and develop successfully we can become an indispensable part of your business operations in Eastern Europe; hence our name: SINE QUA NON.
