Justin Alsterberg spent the first part of his career with a large New Orleans area law firm before leaving to join Julie Quinn and start Quinn Alsterberg . A seasoned litigator, especially involving complex claims, Mr. Alsterberg had his first significant trial success after his first year out of law school, serving as co-lead counsel in a three-week trial in Federal Court on behalf of one of the world’s largest centrifugal pump manufacturers. Justin delivered the closing argument and obtained a multi-million-dollar judgment against the company’s former employees for their theft of the company’s intellectual property and trade secrets. Since then, he has continued to have success in the courtroom, handling both bench trials and jury trials in state and federal courts as well as complex, multi-party arbitration proceedings. Mr. Alsterberg is considered a leader in construction law matters, where he has vast experience managing all aspects of development from design defects, construction defects, payment disputes, insurance coverage and all related matters. However, Mr. Alsterberg also has experience in many other areas of litigation and complex litigation, including oil and gas matters, insurance coverage disputes, maritime matters, and personal injury claims.

Mr. Alsterberg’s clients range from developers, insurers, and members of the trucking and transportation industry all the way to individuals. His significant experience has resulted in success not just at the trial level, but at the appellate level arguing before the Louisiana Supreme Court, the United States Court of Appeals for the Fifth Circuit, and numerous Louisiana Courts of Appeal. Indeed, Justin holds the current record for the largest arbitration award to be overturned on appeal in Louisiana – a matter where he successfully argued that the arbitrators had overstepped their authority in rendering a $1.4 million breach of contract judgment against his client, a family-owned plumbing company that was faced with the prospect of going out of business if the judgment was upheld.

Originally hailing from Michigan, Mr. Alsterberg moved to New Orleans after graduating from the University of Michigan with Honors to attend Tulane Law School, and quickly determined that New Orleans was home. He was admitted to the Louisiana Bar in 2007, and is admitted to practice in all Louisiana state courts, Louisiana federal district courts and the United States Court of Appeals for the Fifth Circuit. He is a member of the Louisiana State Bar Association, New Orleans Bar Association, Federal Bar Association, and the Defense Research Institute. He also serves on the Executive Leadership Committee of Evacuteer, a nonprofit whose mission is to recruit and train volunteers to assist the City of New Orleans in the evacuation of its residents who do not have their own transportation in the event a hurricane threatens the city.
