Chris Massenburg is a partner based in MG+M’s New York and New Orleans offices. His practice primarily focuses on environmental, toxic tort, products liability, commercial trucking and transportation, premises liability, and construction defects litigation. Chris currently serves as National Coordinating Counsel for one of the most iconic brands in the world, is on National Trial Teams for multiple clients, and has tried cases in Louisiana, California, Texas, New York, Alabama, Georgia, South Carolina, Pennsylvania, Kentucky, Maryland, Mississippi, Delaware, Washington, Wyoming, West Virginia, and Oregon. He has defended his clients in numerous cases as lead trial counsel, and has secured multiple zero-dollar defense verdicts by successfully showing juries that his clients did not do anything wrong.

Specifically in asbestos litigation, Chris has tried cases in 15 states for numerous clients and has represented a diverse set of asbestos-related liabilities nationwide, including: friction, gaskets, packing and related equipment (valves, pumps, boilers, digesters, tanks, turbines), joint compound, floor tile, A/C pipe, resin pipe, cosmetic talc, HVAC, PPE (respirators), commercial and military aircraft, electrical equipment, typecasting machines, plastics and molded materials, premises, and contractors. This work has provided Chris with a deep knowledge of the history and science available to demonstrate his clients' innocence, which he uses to innovate new ways to protect all of the companies that trust him with their defense.

Even when trial is not desired, Chris’ experience at all levels of simple and complex litigation allows him to provide his clients with a comprehensive defense for their cases. Chris has been retained by clients to reevaluate their litigation strategies; develop and defend fact, corporate, and expert witnesses in deposition and trial; negotiate the resolution of multi-million dollar risks; and to step in and try high stakes cases, even on short notice.

Licensed to practice law in Louisiana, New York, New Jersey, California, Pennsylvania, Texas, Mississippi, and Tennessee, Chris earned his J.D. in 2000 from Tulane University Law School, and also achieved a certification in maritime law. Chris has served on the Trial Advocacy faculty of both Tulane and LSU law schools, is a current faculty member of the National Institute for Trial Advocacy (NITA), a member of ABOTA, and board certified in both Civil Law Trial and Civil Practice Advocacy by the National Board of Trial Advocacy. Chris is AV® Peer and Client Review-Rated by Martindale-Hubbell, and has been repeatedly recognized by both Super Lawyers (Louisiana and Mississippi) and Best Lawyers in America. Chris has also been recognized locally as a back-to-back winner of the New Orleans CityBusiness "Leadership in Law" Award (2019-2020).

  • "Chris is an absolutely stellar litigator. He is practical, focused and very cost effective. I recommend him without hesitation."
  • "Chris provided excellent service and achieved a favorable resolution to the case we hired him on. I would absolutely hire him again and I can't recommend him highly enough."
  • “Chris is an extremely effective litigator and has a well-deserved reputation as one of the top asbestos defense trial attorneys in the country. I would recommend him to try a case for anyone in the asbestos field.”

Representative Samples of Jurors' Post-Trial Comments:

  • "He was really strong. Obviously he did his research. The more you learned about the case ... I assumed he is a specialist when it comes to these kinds of cases. He was better at cross examination than the [opposing counsel]."
  • "He’s a 10. I remember Chris. He was another fireball. Our nickname for him was Tom Cruise." 
  • "Tom Cruise is a 10. Very impressive. He basically said that his company didn’t have really anything to do with this. He was kind of like, ‘Why am I here?’ and he was actually good enough to make me ask that question: why were they?"
  • "He was great. I could connect with the way in which he explained things. I liked that he was not rude like [opposing counsel] when questioning witnesses. He got his point across and was respectful. One thing that he did, which I liked, was that he would say, 'So you’re telling me this means ...' like he was summarizing the point that he was trying to get across. I liked the way he approached questioning the witnesses."
  • "The main defense lawyer [Mr. Massenburg] was good. He was able to keep the same temperament and demeanor throughout the trial, regardless of what was said. He was the strongest."
  • “Chris Massenburg! I’ll never forget that name as long as I live... We called him “The Ripper,” because he ripped 'em up!"
  • "He had Southern charisma and was a good talker. He seemed like he had a sarcastic, skeptical manner to him. He was very no-nonsense, but also likeable."
  • "He was ruthless, but not in a bad way. It was almost like watching TV when the two main attorneys were against each other. Mr. Massenburg never stepped down. He shocked a lot of us and was a ruthless type of attorney but it worked. He was really knowledgeable."
  • "The limelight was on Mr. Massenburg out of all of the defense attorneys. He was very impressive and knowledgeable. I give him credit for defending his client to the hilt."
  • "Chris was marvelous and his team ran like a well-oiled machine."
  • "He was affable, personable, and genuine...With my background, I appreciated that he relied heavily on the science in his presentation."
