Bartosz Dzionsko's clients include entrepreneurs, large and medium-sized companies, high net worth individuals and crypto investors, whom he successfully represents before criminal, civil and financial courts. He is a sought-after interview partner (e.g. SAT.1 and n-tv, Radio Bob, Radio PSR, Radio RSH und delta radio) and regularly publishes in specialist journals.

Before joining DREYENBERG, Bartosz Dzionsko worked for various renowned law firms in Germany and abroad. Most recently, he worked for a successful medium-sized corporate law firm in Frankfurt am Main as an attorney-at-law and head of the tax and white collar defense and customs law departments.
