Professional Biography

Ms. Champagne has tried approximately 12 cases to jury verdict and three bench trials. She has briefed dozens of appellate matters, including direct and interlocutory appeals, mandamus proceedings, and petitions for review, and has successfully argued before both state and federal courts.

Ms. Champagne also serves regularly as appellate counsel at the trial level, taking on roles ranging from advising on pre-trial motions, preparing jury instructions and "monitoring" trials to seamlessly integrating with an existing trial team from another firm days before a nearly month-long trial and assuming primary responsibility for all aspects of error preservation and motions practice.

Ms. Champagne holds a degree in chemical engineering and practiced in that field for a number of years before entering law school. As a project/process engineer for a major energy corporation, she oversaw capital projects as well as the optimizing of existing natural gas processing operations in Louisiana. She also worked as a consulting engineer for a global engineering, design and construction firm, where she focused primarily on providing environmental services to the chemical and petrochemical industries.
