Who Is Moira Penza?
Moira Penza is a partner at Wilkinson Stekloff, a respected litigation boutique. Before entering private practice, she served as an Assistant U.S. Attorney in the Eastern District of New York. There she handled complex white-collar and violent crime cases, earning a reputation for sharp trial skills and steady leadership.
She is widely recognized for her work as first-chair prosecutor in the 2019 trial of Keith Raniere. That six-week case resulted in Raniere’s conviction on all counts, including racketeering and sex trafficking. The prosecution drew international attention, was featured in the HBO series The Vow, and is often credited with helping open the door for other high-profile sex-trafficking cases.
Penza has since been named to lists such as City & State New York’s Law Power 100, Crain’s New York Business 40 Under 40, and Lawdragon’s leading lawyers rankings. Colleagues describe her as both confident and grounded—a combination that resonates with juries and clients alike.
