Warsaw. Poland.

THOMAS has been founded for professionals by professionals, by people for who finance is not only a profession, but also a passion.
THOMAS has been founded for people of business that need a partner, who will support them in daily affairs. For small and big, for domestic and foreign, for experienced and beginners.

We owe our biggest successes the way we work. We don’t work for our clients. We work with them developing their businesses. In case of problems, if any, we look for solutions together.

Through our international partners, we also have access to a global network of equally competent offices, in which we have strong confidence. It allows us to support our clients not only in Poland, but also abroad.
