Biography

Naomi Zwillenberg’s practice focuses on healthcare-related False Claims Act (“FCA”) and Anti-Kickback Statute (“AKS”) matters, while also encompassing complex business litigation, products liability defense, and white collar investigations. She represents companies and individuals in high-stakes disputes and government enforcement matters involving allegations of healthcare fraud, regulatory noncompliance, and related civil and criminal exposure.

Naomi has substantial experience advising and defending healthcare and life sciences clients in FCA and qui tam actions, including matters involving billing and reimbursement practices, pricing and contracting structures, distribution and shipping practices, and compliance with federal healthcare statutes. She regularly counsels clients through internal investigations, responses to subpoenas and civil investigative demands, and parallel civil and criminal proceedings, and works closely with co-counsel and regulators to develop strategic, fact-driven defenses grounded in industry practice and evolving enforcement trends.

Her life sciences experience includes defending an orthopedic device manufacturer, a pharmaceutical distribution company accused of improper shipping practices, and a drug manufacturer in matters arising from the opioid crisis. Naomi also delivers strategic defenses in cases involving alleged violations of the AKS and related FCA exposure, where her healthcare-focused insight has helped clients navigate complex regulatory and enforcement landscapes.

In addition to her healthcare enforcement work, Naomi maintains a robust business litigation and trial practice. She has handled a wide range of commercial disputes and complex tort matters, and was an integral member of a litigation team that achieved favorable settlements in wrongful death actions brought against a nationwide manufacturer of child products.

Naomi counsels and represents individuals and institutions in the following areas:

  • Healthcare-related False Claims Act matters, including qui tam actions
  • Anti-Kickback Statute and healthcare fraud investigations
  • White collar and government investigations involving healthcare, life sciences, antitrust, public corruption, and government contracts
  • Internal corporate and compliance investigations
  • Whistleblower and fraud-related disputes
  • Business and contract disputes
  • Complex tort and products liability matters

She has received Blank Rome’s Pro Bono Awards for consistently providing more than 65 hours of service each year. Naomi is a volunteer attorney with the Support Center for Child Advocates and the Pennsylvania Innocence Project, and also assists refugees seeking citizenship through HIAS-Pennsylvania. Her pro bono work further includes helping indigent clients prepare essential legal documents, including birth certificates, wills, and end-of-life planning materials.

In recognition of her work with the Pennsylvania Innocence Project, Naomi was a co-recipient of Blank Rome’s 2024 Edwin P. Rome Pro Bono Achievement Award, which honors outstanding commitment to pro bono legal service.

While in law school, Naomi was the associate editor of the Journal of Law and Social Change and earned a Certificate in Management from the University of Pennsylvania Wharton School. She also served as a judicial intern for the Honorable Richard Lee Price of the Bronx County Supreme Court – Criminal Division. When she was at New York University, she was a University Honors Scholar, a President’s Service Award Recipient (2009), and on the Dean’s list (2005–2009).
