18 years of MDDP

We thank our clients for their trust and continued inspiration – without you, our existence would be pointless. We thank our employees for their contribution to building and developing MDDP. To those still on board and to those who have moved on in their professional careers but are still part of the great MDDP family – our Alumni.

It is thanks to the people who contribute to MDDP’s growth on a daily basis that we are where we are and look boldly and courageously into the future. 18 years means that we have accumulated a lot of experience. We are proud and happy to say that we have built one of the largest consulting companies in Poland. And we still have the courage to reach for the stars, to forge new paths, we still have the hunger to take on new challenges, including those that are not obvious.

 Thank you for being with us!
