James M. Ardoin

Jimmy Ardoin has spent more than twenty years doing what most trial lawyers avoid: taking the hard cases. The ones with short timelines, complicated facts, and opponents who expect you to flinch. He doesn't.

Based in Houston, Jimmy represents clients in serious personal injury litigation — with a focus on trucking and oilfield accidents — complex business disputes, and federal white-collar criminal defense. His practice is built on a premise that few attorneys can honestly claim: he has fought on both sides of the civil-criminal divide at the highest levels, and that experience changes how he approaches every case.

On the civil side, Jimmy has secured million-dollar verdicts for clients whose businesses were stolen, whose families were devastated by commercial trucking negligence, and whose livelihoods were destroyed by fraud. On the criminal side, he has stood beside individuals and corporations facing federal indictments, grand jury investigations, SEC enforcement actions, and sanctions violations — securing dismissals, reversals, and results that changed lives.

His 2025 $10,000,000 jury verdict — obtained after taking over a business theft case just four weeks before trial — reflects the standard he holds himself to in every matter he accepts.

Jimmy is admitted in all four federal districts in Texas and before the Fifth and Fourth Circuit Courts of Appeals. He is a recurring Texas Super Lawyer in White-Collar Criminal Defense, a National Trial Lawyers Top 100 honoree, and a graduate of South Texas College of Law.

He takes the cases he believes in. He prepares like every trial is the most important one of his career. And he fights like his client's future depends on it — because it does.
