"Jacek can relate to a client’s needs and provide to the point guidance. Jacek’s thorough advice on a commercial transaction I had, saved me a lot of money. Apart from an outstanding professional however Jacek also has an excellent character with the ability to relate to persons and circumstances. For all these reasons I recommend him without any hesitation for your legal issues as well as a legal mentor to support your business through development but also navigate through day to day matters before escalating into legal issues."

"Media Gremi Company (formerly knowns as PRESSPUBLICA) is a publishing company located in Warsaw, Poland. The Company is the publisher of the Polish newspapers such as "The Rzeczpospolita", "Bloomberg Businessweek Poland", "Parkiet". Because of the subject matter and the size of the business the Company employs in-house lawyers but it also works with external law firms. One of them was Cieszynski Law Group LLC of New Jersey, USA. Jacek has done a professionally and fairly good job, with particular regard to the interests of the Company in the United States. It is also worth emphasizing the fact that Cieszynski Law Group LLC has completed the project in a highly ethical manner. As a general counsel to the Company, I was in constant contact with Mr. Cieszynski and I consider our cooperation as a successful and rewarding one. I can recommend the Cieszynski Law Group LLC as a credible and reliable partner."
