Since 1998, Mark D. Sherman has been a member in good standing of the State Bars of Connecticut, New York and Florida.
His practice focuses on criminal and civil litigation, serving clients in the Connecticut and New York metropolitan areas. Mark has successfully handled scores of serious and sensitive criminal and employment matters, some of which have received high profile media attention.
- In 2010, Mark made history by procuring the largest whistle-blowing bounty award in SEC history on behalf of his client for her participation in an SEC insider trading investigation.
- In 2008, Mark received national attention for his representation of Leonard Trujillo, Jr., who faced capital murder charges for his role in the death of Greenwich businessman Andrew Kissel. The capital murder charges were ultimately dropped, and Mr. Trujillo pled to reduced charges.
Mark prides himself on the time and attention he gives to all of his clients—whether high or low profile—and recognizes that while the legal profession is primarily technical and academic, it is also a service business. To that end, he works to ensure that all of his clients receive the highest degree of service, time and attention, seven days a week.
Mark has also appeared as a guest commentator on Court TV, Fox News and ESPN. He also routinely lectures to schools and parents’ groups on cyber-safety and the dangers and perils for kids growing up in today’s techno-centric society.
Mark graduated from the University of Pennsylvania in 1995 and subsequently earned his law degree at the Fordham University School of Law in 1998, where he served as President of the Student Bar Association. After law school, Mark joined the litigation department of the New York law firm of Pryor, Cashman, Sherman & Flynn, practicing in their litigation group and later left to start his own practice.
