For more than 25 years, we’ve stood beside individuals and families across Louisiana who have suffered catastrophic injuries, lost loved ones to wrongful death, or faced life-changing harm caused by someone else’s negligence.
At The Marionneaux Law Group, we believe personal injury law is about more than financial compensation. It’s about helping good people during their hardest moments — with honesty, compassion, and the kind of relentless advocacy we’d want for our own families.
A Personal Perspective on Personal Injury Law
Attorney Robert “Rob” Marionneaux, Jr. brings a unique perspective to this work—not just as a seasoned trial lawyer, but as someone who has personally been on the other side of a serious injury case.
Earlier in life, Rob himself was severely injured in a motor vehicle accident. He knows firsthand what it is like to face pain, uncertainty, and financial pressure while battling a powerful company for fair compensation.
That experience shapes how we approach every case at our firm. We understand what injury victims go through—physically, emotionally, and financially. And we are committed to helping clients fight back, so they are not overwhelmed or taken advantage of by corporations or insurance companies with deep pockets and aggressive legal teams.
A Legacy of Trial Success
Rob Marionneaux has spent his career fighting for the injured in courtrooms across Louisiana. He has tried numerous civil jury cases to verdict, with results that include jury verdicts totaling more than half a billion dollars. His work has earned membership in the Million Dollar Advocates Forum and Multi-Million Dollar Advocates Forum—organizations that recognize attorneys who have achieved million and multi-million dollar results for their clients.
With over 25 years of courtroom experience, Rob has served as lead counsel in high-stakes personal injury cases, class action lawsuits, and catastrophic injury claims. He is also an accomplished appellate advocate, having argued before all five Louisiana Courts of Appeal and the Louisiana Supreme Court.
In addition, Rob regularly speaks at continuing legal education seminars on advanced litigation topics such as handling traumatic brain injury cases and preparing complex trucking accident cases for trial.
The Next Generation of Advocacy
Today, the firm’s legacy continues with Robert Marionneaux III — a trial lawyer born and raised in Iberville Parish, who brings passion, empathy, and a deep commitment to helping Louisiana families. Long before becoming an attorney, Robert III was immersed in public service and the legal world. But in 2020, everything became personal: he was seriously injured in a motor vehicle accident that required multiple spine surgeries and ultimately went to trial.
That experience changed him — and it shapes how we approach every client’s case. When Robert III says he understands what you’re going through, it’s not just talk. He’s lived it. That’s the heart behind our practice.
A Different Kind of Personal Injury Firm
Many personal injury firms take a “volume” approach, moving as many cases as possible through the system and accepting quick settlements. That’s not how we practice law.
At The Marionneaux Law Group, we take a more focused, personal approach. We handle a limited number of cases at a time, so each client receives the full benefit of our time, attention, and resources. Every case is prepared from day one with the expectation that it may go to trial, because serious preparation is what produces the best results.
Our goal is to provide every client with compassionate support and aggressive legal representation. We understand that choosing a lawyer after a serious injury is one of the most important decisions you will ever make. That’s why we fight as hard for our clients as we would for our own families.
Focused on Serious Injury and Wrongful Death Cases
We concentrate on complex personal injury cases, including catastrophic injury, truck and commercial vehicle accidents, industrial accidents, traumatic brain injuries, wrongful death, and serious motor vehicle accidents. These are often high-stakes cases that require in-depth knowledge of the law, extensive resources, and the skill to present compelling cases to judges and juries.
When you work with us, you can expect determined advocacy from lawyers who understand how to stand up to corporations, insurance companies, and powerful defendants.
If you’ve been injured in a car accident, harmed on the job, and need help navigating workers’ compensation, or have lost a loved one to wrongful death, we are here to help.
Deep Louisiana Roots, Generations of Service
Our firm is based in Baton Rouge, but our ties to Louisiana run much deeper. Rob Marionneaux is a graduate of Louisiana State University and Southern University Law Center, where he was inducted into the Hall of Fame. He is proud to have spent his entire legal career advocating for Louisiana families.
Today, that legacy of service continues with Rob’s son, Robert Marionneaux III, who is now carrying forward the family tradition as a passionate young trial lawyer.
Our team views our clients not just as cases, but as neighbors and friends. We never forget the human impact of the cases we handle, and we take pride in fighting for justice on behalf of Louisiana families.
