Veteran trial attorney Jack Wenik positions clients, both business entities and individuals, to reduce the risks—from fines to corporate integrity agreements, Medicare/Medicaid exclusion, and prison time—of investigations and litigation by the government. Jack protects health and wellness clients’ livelihoods and reputations in credible, scientifically driven defense strategies before the U.S. Department of Justice (DOJ), the U.S. Food and Drug Administration, the Federal Trade Commission, State Attorney General’s offices, and other agencies. His clients include a wide range of health care providers, including physicians, hospitals, pharmacies, nursing homes, home health agencies, adult day care centers, telehealth providers, executives, and dietary supplement makers and distributors that face civil and criminal allegations. Jack also guides dietary supplement companies and health care providers in class action litigation and commercial litigation disputes.

Jack steers clients from the government’s first inquiry into fraud, abuse, and other wrongdoing. A former Assistant U.S. Attorney and the son of a police officer, Jack combines a deep understanding of investigations and regulatory structures with productive agency relationships he has built during more than 25 years of private practice.

His impact in settlement negotiations and at trial are evident in the favorable client outcomes Jack achieves—from declination, decriminalization, or reduction of charges to preservation of medical licenses and more. In addition to leading litigation challenges with government agencies, Jack contributes to clients’ virtual trial teams, especially in scientific expert testimony.

Clients in the dietary supplement sector rely on Jack’s technical strength to defend them against claims of product adulteration, misleading advertising, product liability, and other regulatory violations. In his preventive advertising reviews and litigation counseling, Jack aims to prevent stifling clients’ innovation without running afoul of the government.
