Jeffrey J. Ansley
Biography

Jeff Ansley is a white collar trial lawyer and the head of Bell Nunnally’s White Collar Criminal and Regulatory Defense practice. Before joining the firm, he served as both an Assistant United States Attorney for the Northern District of Texas and Enforcement Attorney for the United States Securities and Exchange Commission.


Jeff 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. As a former federal prosecutor, he has an insider’s knowledge of the tactics and resources used by prosecutors and investigators, and so knows how to combat them. Jeff has long been a white collar trial lawyer with a special focus on health care fraud, securities enforcement, and other alleged business crimes.

Jeff represents targets of government health care investigations and prosecutions. His clients include physicians, hospitals, compounding pharmacies and their personnel, and medical organizations and suppliers. In doing so, he has significant experience with matters handled by the Department of Justice, the Medicare Fraud Strike Force, the Department of Defense, and the Health and Human Services - Office of Inspector, among others. Jeff also counsels clients in securities enforcement cases arising from securities offerings and stock trading activities, representing officers, directors, independent committees and boards, and other professionals in high-stakes securities cases. 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 come with them.

He also handles federal and state administrative actions instituted by securities and health care regulators, including acting as counsel for corporations and their officers and directors, physicians and physician groups, broker-dealers, investment advisers, and other professionals and organizations.

Jeff also conducts internal investigations on behalf of corporate clients involving allegations of securities, health care, and tax fraud, employee misconduct, possible violations under the Federal Corrupt Practices Act, and trade secret theft violations, among other suspected misconduct. In addition, he develops compliance and ethics programs for corporations and other business entities. Texas Monthly and D Magazine have consistently recognized him for his white collar and regulatory defense practice.
