About us

Warsaw-based Law Firm PIERÓG & Partners was founded by Jerzy Pieróg, advocate, one of the pioneers of public procurement in Poland and an undisputed authority in this field.

Over the years, he has built up a team of competent lawyers capable of solving the most difficult problems and tackling the greatest challenges. As the most experienced lawyer, he oversees work on particularly important and complex cases.

On a day-to-day basis, the team has been led for almost 10 years by Joanna Presz-Król, attorney at-law and managing partner. Her extensive experience in public procurement and, at the same time, her ability to work with clients, allows the entire Law Firm to operate smoothly.

Every single move is carefully considered. We always choose the most optimal legal solutions. We choose the best, proven and trusted players to play.

Jerzy Pieróg Founder Pieróg & Partnerzy

25 years on the market


Jerzy Pieróg leaves the Public Procurement Office, where he created the appeals system, serving as director of the Appeals Team, organising the work of arbitration panels. For the first year, he provides legal services as part of a civil-law business partnership [spółka cywilna].


The following years involve individual activities within the JTP Law Firm, focusing primarily on public procurement services. It was then that such entities as Poczta Polska, TVP, Budimex SA or Elektrociepłownie Warszawskie (later Vattenfall SA, now PGNiG Termika) became the Firm's clients.


Jerzy Pieróg steps down from his position as arbitrator appointed by the President of the Public Procurement Office, which he held since 1996, adjudicating and chairing hundreds of arbitration hearings concerning the largest and most important contracts in Poland. He devotes himself entirely to the development of his law firm operating in Żoliborz on Krasińskiego Street.


The launch of the new objectives for the development of an expert legal brand and the building of a team advising clients on all aspects of public procurement now takes place in a new prestigious location in the heart of Warsaw at Three Crosses Square.


A consultancy and training contract with the Polish Agency for Enterprise Development (PARP) results in a significant growth for the JTP Law Firm. It covers hundreds of public and private entities from all over Poland.

A period of intensive work, expansion of the team and constant broadening of knowledge, which contributes to further dynamic development of the Law Firm. During this period, as a result of careful selection, Jerzy Pieróg created a team of a dozen or so professionals, attorneys at-law, advocates and lawyers (trainees and PhD students).
