About Sheldon T. Zenner
Drawing on nearly 40 years of combined experience as a federal prosecutor and defense attorney, Sheldon Zenner expertly navigates his clients through high-stakes matters, including government and internal investigations, regulatory proceedings, all phases of criminal matters and related civil litigation. Sheldon's diverse client base is made up of corporations, high-ranking executives and company owners across a wide range of industries, including financial services, health care and entertainment. Importantly, his representation of clients goes beyond advising on purely legal issues; it encompasses practical business implications, operational issues, public scrutiny, reputational damage and other considerations relevant to corporate and individual clients with businesses or livelihoods on the line.
A prosecutor's perspective
The foundation of Sheldon's white-collar defense practice is the seven years he served as an assistant US attorney in Chicago, prosecuting hundreds of high-profile criminal matters and supervising the work of junior line prosecutors. Having a prosecutorial background gives Sheldon critical insights into, and the ability to anticipate, the government's strategic decision-making. It also informs Sheldon's approach as a defense lawyer. Although never anything short of zealous, he favors a search for common ground and reasonableness, whenever possible, over unproductive displays of aggression.
"He is a very experienced trial attorney who is trusted by clients."
