To defend health care, financial services, and other companies under government investigation, attorney Melissa Jampol uses strategic insights gained from her many years as a federal and New York state prosecutor. A fierce, trial-proven advocate, Melissa prepares clients for complex civil and criminal investigations and litigation in a shifting regulatory environment.

Her clients include a wide range of health care providers: clinical laboratories, pharmacies, nursing homes, drug treatment centers, adult day care providers, telehealth providers, hospital systems, and physicians. Her clients also include numerous other kinds of entities, such as public and private schools, credit unions, tech companies, dietary supplement makers, and retailers. Melissa routinely represents individuals, officers, directors, and boards of directors.

Melissa’s prior immersion in the prosecutorial mindset helps clients anticipate and resolve investigations, inquiries, litigation, and charges. To keep clients out of authorities’ crosshairs, Melissa advises proactively on self-remediation and enhanced compliance protocols and assists clients with managing risk in mergers and acquisitions. Her clients appreciate her empathy and clear communication with judges, juries, experts, corporate leaders, government regulators, and others. Clients also value her ability to resolve tough allegations—health care fraud, False Claims Act (FCA) (including qui tam litigation), financial crimes, and criminal antitrust, among other claims—with decisions of nonintervention, declination of charges, reduced penalties, and no criminal referral. Melissa understands the reputational risk that accompanies even the hint that an individual or a company is under government investigation.
