D'Ann Penner

D'Ann Penner's Headshot

Business Tort Top 10Dee Penner represents companies, state agencies safeguarding Louisiana’s wildlife management areas, and landowners throughout Louisiana in various civil litigation matters. In particular, she focuses on the litigation portfolio of land-loss cases filed with Tony on behalf of the Louisiana Department of Wildlife and Fisheries. The goal of these cases is to require the pipeline companies who have breached their contracts with the Department to honor their word and restore the wetlands they destroyed in various wildlife management areas and refuges.

A Well-Prepared Attorney in Pursuit of Justice

Along her path to a distinguished legal career, Dee traversed through rewarding careers as an academician and a narrator of present-day history in the making. Today, she pursues justice for the Department, landowners, business owners, injury victims, and other clients, often up against formidable forces from corporate and government entities.


From a country upbringing in the Midwest to the halls of major state universities and stints as a researcher in the backwaters of Russia in the early days of the breakup of the Soviet Union, Dee quenched her thirst for knowledge with a drive to win in every undertaking. As a scholar, traveler, and teacher focusing on Russian history, language, and culture, Dee gained a keen appreciation for people’s deep connections to land and community. As a historian, she developed a talent for uncovering facts and storytelling.

Later, back in America, Dee parsed the real-life sagas of loss, grit, and recovery experienced by survivors of Hurricane Katrina on her path to book writing. In this role, Dee nurtured a deep respect for the priorities and values of hardworking Louisianans.

The daughter and granddaughter of small farmers, Dee is passionate about providing quality legal representation to landowners who have been wrongly deprived of their rights. She has litigated a wide variety of property rights, breach-of-contract, and public trust claims in state and federal courts. She has briefed appellate matters before the Louisiana Supreme Court, Louisiana Circuit Courts of Appeal, and the U.S. Court of Appeals for the 5th Circuit.

Dee represents clients in various civil litigation matters, including unfair trade practice claims, pipeline trespass cases, property damage cases, land-loss cases, and toxic torts. She has represented several landowners sued by pipeline companies that were trying to seize the landowners’ land for pennies on the dollar. Dee works for landowners of all sizes facing companies seeking right-of-way agreements or leases. She handles all aspects of litigation, from client intake and trial through appeals.

Dee works with Tony Clayton on dozens of major class actions and mass torts for landowners, crawfish farmers, shrimpers, the Louisiana Department of Wildlife and Fisheries, business owners, and employees in state and federal court. The plaintiffs’ causes of action run the gamut from unfair trade practices to trespass claims, from breach of contract to oil/brine spill contamination claims, from defamation to tortious interference with business relations claims. The point of these cases to keep bullies, whether corporations or individuals, from prospering from wanton damage to the land, the reputation, and the health of our clients and to make our clients whole. She also works with Brilliant Clayton on personal injury and premises liability cases.

From 2018 through 2023, Dee was selected to be part of the Louisiana Super Lawyers Rising Stars list, an honor given to no more than 2.5% of the lawyers in the state who are either 40 or younger or have been practicing for ten or fewer years. She was named in The National Trial Lawyers: Top 100 Trial Lawyers rankings for civil law in Louisiana in 2020-2023. From 2021- 2023, she was named on the National Trial Lawyers organization’s Top 10 Business Tort Trial Lawyers list. Dee has also been featured in the 2023 Louisiana Super Lawyers Magazine!

Dee earned her J.D. at Loyola University New Orleans College of Law and two Masters of Law degrees, the first in environmental law from Tulane University and the second from Baylor Law School in litigation management. Dee earned a Ph.D. in history from the University of California. She was a tenured history professor at the University of Memphis and the director of the Benjamin L. Hooks Institute for Social Change before she traded academia for the law. The co-author of two books, Dee has also written two law review articles and seven articles for the Louisiana Association for Justice’s monthly magazine.

Personal Background

Raised on a farm near a small town – population of 200 – Dee grew up working in her dad’s soybean fields and driving tractors from an early age. She now lives along the Mississippi River and enjoys listening to the blues, jazz, and country music; cooking; reading; boxing; forest restoration; woodland gardening; hiking; and traveling the backroads around Louisiana.

Dee has published two books: one on the forced famine of 1932 and 1933 in Communist Russia and its impact on oppressed farming people and another about New Orleanians who triumphed over the tragedy of Hurricane Katrina through hard work, creativity, and perseverance.
