Kate Mancuso understands that in business, reputation is everything. Kate knows how to protect a client's integrity and brand value when high-profile litigation threatens both.

Prior to joining Hogan Lovells, Kate was a Series 7 and Series 66 licensed financial advisor and a business owner, where she learned how to anticipate her clients' needs and create detailed solutions to complex problems. As a litigation associate in Philadelphia, Kate’s practice focuses on complex commercial litigation and internal investigations, with particular focus on the healthcare industry. Kate has a keen sense for facts and details that makes her an asset on any team and enables her to craft compelling arguments in the face of challenging legal issues. But more importantly, Kate understands that pending litigation affects a business well before the final outcome of the matter, and she helps her clients communicate effectively with customers and business partners to minimize the impact on a company’s bottom line. 

Kate has extensive experience in federal multidistrict litigation and coordinated state-level proceedings, and knows how to work effectively with joint defense counsel and plaintiffs’ counsel to protect her client’s long-term interests. She is equally comfortable leading a team or taking on a supporting role as needed, and she can be trusted to spot potential issues early on and identify smart solutions.

Kate’s pro bono efforts include Social Security appeals for individuals who were wrongfully denied benefits, and she is currently representing the City of Philadelphia on a petition for allocatur before the Pennsylvania Supreme Court relating to municipal authority to regulate firearms. During her time at Penn Law, Kate had the honor of serving as a Littleton Fellow and was Executive Editor for The Regulatory Review. She lives in Philadelphia with her husband, Tim, and their two dogs, Sinatra and Guinness.

Kate is on secondment at a firm client from May 2024 to November 2024.
