General

Jeff Ansley defends individuals and companies facing high-stakes criminal charges, government investigations, and regulatory enforcement actions.

contentpilot/introduction

With more than 30 years of experience, including nearly a decade as a federal prosecutor, Jeff maintains one of the most active federal trial practices in Texas and is known for guiding clients through their most serious legal and business risks.

core/paragraph

As former head of the Department of Justice’s Complex Fraud Task Force for the Northern District of Texas, Jeff draws on deep government insight to defend his clients in federal investigations and cases involving the Justice Department, the Securities and Exchange Commission, and U.S. Attorneys’ Offices nationwide. He represents Fortune 500 companies, executives, physicians, and other professionals in matters involving alleged fraud, securities violations, kickbacks, corruption, and corporate misconduct. Jeff also advises clients on immigration-related compliance and employment practices, conducts internal investigations, and handles False Claims Act matters and along with related civil and administrative proceedings.

Clients rely on Jeff to help them avoid liability, minimize business disruption, and protect their reputations. He understands how prosecutors builds cases and uses that perspective to anticipate strategy, narrow exposure, and often resolve matters before charges are filed. His results include high-profile acquittals in cases where the government sought decades of imprisonment and massive financial penalties.

Jeff combines trial-tested courtroom skills with a strategic approach that emphasizes early intervention and practical problem solving. He excels at identifying and leveraging weakness in the government’s case, managing crises with discretion, and balancing strong courtroom advocacy with effective negotiation. His approach consistently delivers outcomes that allow clients to protect their businesses, safeguard their reputations, and move forward with confidence. &nbsp;
