Jon F. “Jack” Carmer, Jr.


Jon F. “Jack” Carmer, Jr. is an experienced litigator representing clients in federal and state courts across Louisiana and Mississippi. His practice is expansive and varied, including general liability, professional liability defense, toxic torts, tax litigation, bankruptcies, and civil litigation. Jack relentlessly pursues his client’s objectives with the “Three Ds,” detail, diligence, and dedication.  He understands how to keep litigation simple and direct while finding creative solutions for his clients.

Jack devoted the first years of his practice to the economically disadvantaged as a staff attorney and director of a Low-Income Taxpayer Clinic (“LITC”) with North Mississippi Rural Legal Services, assisting clients experiencing domestic turmoil, foreclosure, eviction, wage garnishment, and adverse IRS collection actions.  Jack’s tenure with the LITC piqued his interest in tax law, leading him to the Mississippi Department of Revenue.  There, he managed litigation matters from start to finish, both at the trial and appellate court level, as well as in federal bankruptcy court, with multiple reported cases to his credit. He then transitioned over to Louisiana law to be closer to family, administratively prosecuting violations of alcohol, tobacco, and CBD law for the Louisiana Office of Alcohol and Tobacco Control, which included navigating compliance issues during the COVID-19 pandemic.  Most recently, and prior to joining Maron Marvel, Jack served as investigative counsel for the Louisiana State Board of Medical Examiners, streamlining physician/allied healthcare practitioner disciplinary matters and disposing of them in a manner that simultaneously protects the public and ensures fairness to practitioners.
