Troutman Pepper Locke Strengthens Health Care and Life Sciences Litigation Practice With Addition of Ryan O’Neil as Partner in Philadelphia
Well-Known Trial Lawyer Bolsters Firm’s Product Liability and Mass Tort Capabilities
PHILADELPHIA – Ryan J. O’Neil, a respected trial attorney with vast experience trying high-stakes product liability and mass tort cases, has joined Troutman Pepper Locke’s Health Care and Life Sciences Litigation Practice Group as a partner in the firm’s Philadelphia office.
O’Neil joins Troutman Pepper Locke from Campbell Conroy & O’Neil, where he built a nationwide practice defending clients in complex product liability litigation matters across federal and state courts. He has served as national and trial counsel in major product liability and mass tort proceedings, including multidistrict litigations and coordinated state court actions.
Deeply rooted in the health care and life sciences sectors, O’Neil advises clients across an array of industries, including pharmaceuticals and medical devices, nutrition and food science, consumer products, and more. Beyond life sciences, he has significant experience defending Fortune 100 and 500 companies in consumer products, toxic tort, and transportation-related matters, in addition to white collar and internal investigations.
“Ryan has already built a sophisticated, client-driven practice and earned the trust of clients navigating complex regulatory and commercial challenges,” said Sean Fahey, chair of Troutman Pepper Locke’s Health Care and Life Sciences Department. “His decision to join us underscores the strength of our platform and our ability to support clients at every stage of growth.”
O’Neil has widespread experience representing clients in all phases of litigation. His work spans pre-litigation counseling and investigation, motion practice, fact and expert discovery, oral argument, pretrial, trial, and appeal, as well as mediation. He also regularly advises clients on risk management and litigation avoidance strategies.
“Ryan will bring a wide range of litigation and trial skills to the firm. His trial experience and strong presence in Pennsylvania state and federal courts will enhance our capabilities in mass tort and product liability matters, which are key areas of growth for our firm and our Philadelphia office, in particular,” added Joe Imperiale, Philadelphia office managing partner.
“I’ve long respected Troutman Pepper Locke’s work in the health care and life sciences space and have seen firsthand the value the firm brings to clients,” said O’Neil. “Joining Troutman Pepper Locke’s larger, nationally recognized platform will allow me to better serve and drive meaningful outcomes for clients, and I’m eager to partner with my new colleagues to expand our reach.”
Active in both the profession and community, O’Neil is a member of the International Association of Defense Counsel, Defense Research Institute, Philadelphia Association of Defense Counsel, and serves on the board of the Aark Wildlife Education and Rehabilitation Center. He also maintains an active pro bono practice, representing individuals facing homelessness and veterans in benefits and disability matters.
