Corporations and individuals alike turn to Sarah M. Hall, an experienced former federal prosecutor, to represent them in government investigations and prosecutions of alleged violations of the health care, anti-fraud, procurement, Foreign Corrupt Practices Act (FCPA), securities, commodities, and criminal tax laws.

From her many years as a prosecutor with the U.S. Department of Justice (DOJ), Sarah has extensive experience in every phase of a federal criminal case—from investigation to jury trials to appeals.

Clients benefit from Sarah’s insight into how prosecutors and law enforcement agents think, investigate, and try cases. With her firsthand knowledge, Sarah vigorously advocates for her client’s interests—with the goal of persuading law enforcement agencies to decline to pursue criminal charges or other enforcement actions. Because Sarah’s goal is to resolve government investigations without charges or adverse publicity, many of her most important successes for her clients are not publicized. Sarah is also ready, willing, and able to take a federal criminal case to trial where appropriate.

As a former health care fraud prosecutor, Sarah devotes a significant part of her practice to representing companies and individuals in criminal and civil health care enforcement matters, including False Claims Act and state Attorney General investigations. Her health care clients include skilled nursing facilities (SNFs), other long-term care facilities, pharmacies, medical practices, independent diagnostic testing facilities, medical consulting companies, doctors, other licensed medical practitioners, medical industry executives, and sales reps.

Sarah also represents clients in investigations related to CARES Act funding, including the Paycheck Protection Program (PPP) and the Provider Relief Fund (PRF).

Clients also look to Sarah to lead sensitive corporate internal investigations. Her experience in internal investigations includes workplace culture investigations, health care, financial fraud, FCPA violations, export control violations, narcotics in a corporate setting, #MeToo sexual harassment, and whistleblower retaliation. She is also frequently sought out by clients for her skills in civil litigation, including high-stakes and emergency matters, such as temporary restraining orders and preliminary injunctions.

Sarah previously served for seven years as a white-collar crime prosecutor with the Fraud Section of DOJ’s Criminal Division. Sarah began her DOJ career as a prosecutor on the highly successful nationwide Medicare Fraud Strike Force, and she has significant experience prosecuting criminal health care fraud, money laundering, and kickback offenses. In the Securities and Financial Fraud Unit (now known as the Market Integrity and Major Frauds Unit), Sarah investigated and prosecuted some of the most complex financial crimes on Wall Street. Her primary focus was the investigation and prosecution of major global financial institutions, executives, and financial traders.

As a prosecutor, Sarah obtained dozens of convictions, via trial and plea, in six different federal trial courts across the country. Her trial experience includes having served as first chair in federal criminal trials lasting from several weeks to as long as nearly two months in duration.

Before her government service as a DOJ prosecutor, Sarah worked for international law firms, where she defended individuals and corporations in high-profile federal white-collar criminal matters, parallel civil and regulatory investigations, and complex civil litigation. Her practice focused on securities/financial fraud, accounting improprieties, and corporate internal investigations.

Prior to her career as a lawyer, Sarah worked on Capitol Hill for a U.S. senator and a U.S. representative. She focused on Finance and Appropriations Committee matters.
