Jeffrey J. Ansley


Jeff Ansley is a Shareholder in Vedder Price’s Government Investigations & White Collar Defense group and focuses his practice on white collar defense, representing professionals and corporate clients in high stakes investigations and cases before federal prosecutors and in court when the time comes.

He has long been a white collar trial lawyer with a special focus on health care fraud, securities fraud and other alleged business crimes. Mr. Ansley regularly represents individuals and companies in complex matters involving the Department of Justice (DOJ), the U.S. Department of Health and Human Services Office of Inspector General (HHS-OIG), the Medicare Fraud Task Force, the Securities and Exchange Commission (SEC), the Department of Defense (DOD), the Federal Bureau of Investigation and many other government agencies.

Mr. Ansley is a Chambers USA-ranked, seasoned white collar criminal defense trial lawyer and former federal prosecutor for the Northern District of Texas. His practice focuses exclusively on white collar criminal defense, federal grand jury matters, internal investigations and regulatory proceedings, including enforcement actions by federal and state agencies. Mr. Ansley regularly defends individuals and companies in a variety of high stakes federal criminal and regulatory investigations and trials, including health care fraud, securities fraud, wire and mail fraud, honest services fraud, tax fraud, money laundering, anti-kickback and Stark law allegations, bribery and public corruption, among others. Mr. Ansley’s practice routinely places him between his clients and the government.

In the health care industry, he regularly defends physicians and other health care providers, hospitals, practice groups, dentists, DSOs, pharmacists and marketers in criminal and regulatory investigations, prosecutions and trials. In the securities industry, he regularly represents public companies, their officers and directors, broker-dealers, financial advisers and advisory firms, and other securities industry professionals in connection with investigations and proceedings by the DOJ, the SEC, FINRA and state securities regulators.

Mr. Ansley has led numerous internal investigations relating to criminal, regulatory and compliance matters as varied as financial and accounting fraud, health care fraud, the Anti-Kickback Statute and Stark law, public and commercial bribery, employee misconduct, SEC reporting and import-export activities, among others.

Thanks to his combined experience as a former DOJ fraud and public corruption prosecutor and SEC enforcement attorney, Mr. Ansley has an insider’s knowledge of the tactics used by prosecutors and investigators, resources that he uses on behalf of his clients to combat them. This experience makes him uniquely qualified to handle not only these investigations and charges, but also the collateral regulatory, administrative and civil consequences that often accompany them. 

Mr. Ansley is ranked individually by Chambers USA for “Litigation: White-Collar Crime & Government Investigations,” where he is described as “one of my go-to for white-collar matters” and “very, very well versed in healthcare fraud investigations and defense.” He has been selected by his peers for inclusion in The Best Lawyers in America since 2018, was named a “Litigation Star” in the Benchmark Litigation 2020 guide, and has been selected by his peers for inclusion in Texas Super Lawyers since 2010. He has been consistently recognized by Texas Monthly and D Magazine for the strength of his white collar and regulatory defense practice. He is a frequent speaker, author and commentator on white collar matters.
