Katie S. Roth

Katie S. Roth is a commercial litigator with extensive appellate experience in state and federal courts.


Katie represents clients in a wide range of complex commercial disputes.  Her experience includes patent and trademark litigation, director and officer liability, unfair trade practices, class actions, contract disputes, construction litigation, and numerous oil and gas cases of all kinds.  

Additionally, Katie brings to the firm a wealth of experience in appellate law.  She handles appellate matters in the Louisiana Supreme Court, the Louisiana Court of Appeal, the United States Courts of Appeals, and in administrative proceedings.  Her clients seek her expertise in resolving complex appellate procedural issues, preparing appellate briefs and writ applications, oral argument, and assessing the likelihood of success on appeal.  Katie co-authored the “Initial Civil Appeals: Louisiana” and “Additional Civil Appeals: Louisiana” Practical Law State Q&As, published by Thompson Reuters, and she has spoken on a host of appellate topics such as best practices in brief writing, civil writ trends, and the appellate practice for the business litigator, among others. 

On a personal note, most of Katie’s free time revolves around her three children.  Her remaining time is often spent running ultramarathons and dabbling in other sports, such as rock climbing and tennis.  She also enjoys snow skiing with her family, dining out, and staying involved in her community through the Krewe of Iris, the Children’s Hospital Sugarplum Ball, and the Trinity Episcopal School Parents’ Group.
