Leszek Kieliszewski

Corporate Advocate. White-Collar Defense Counsel.

I specialize in commercial, corporate, financial, and white-collar crime cases.

Why clients entrust their cases to me:

Deep operational insight: I gained my professional experience holding executive positions at brokerage houses and asset management firms.
Reputation protection and crisis management: Commercial cases often unfold in the public eye. I design strategies that protect the client, their reputation, and their business – both in court and before the court of public opinion.
Shaping legal discourse: My analyses and columns are regularly featured in Rzeczpospolita, Poland’s leading economic daily. As an author and speaker at industry conferences, I actively set the standards for interpreting regulations rather than merely following them.
Handling high-profile, complex litigation: I represent clients in major, highly sensitive financial fraud cases, including GetBack, Metropolitan Investment, GKFX, and others.

I operate with cold calculation and a strict focus on results, seamlessly adapting tactics to shifting trends and evolving legal circumstances.
