Jason Cincilla is a litigation strategist, litigation manager, and trial lawyer. In 20 years of practice, Jason has helped companies resolve hundreds of high-stakes cases involving products liability; sporting arms, ammunition, and outdoor products; toxic torts; asbestos; infectious diseases and COVID-19; insurance coverage; employment; corporate; and complex commercial litigation. He has tried multiple cases to favorable verdicts, and he has successfully argued more than 75 summary judgment motions applying the laws of many different states and multiple foreign countries.

As partner-in-charge of MG+M’s Delaware office, Jason oversees all of the litigation in the office. He also serves as regional coordinating counsel for five defendants in asbestos litigation, which involves coordinating defense of claims in 20 different states. A self-described “discovery wonk,” Jason serves as national discovery coordinator for all of the companies for which MG+M serves as national coordinating counsel.

Jason believes meticulous preparation is the key to resolving cases successfully. He thoroughly absorbs the facts and law of every case, finding innovative avenues to undermine plaintiffs’ claims. Jason has the unique ability to hyper-focus on the details that decide key motions and limit damages, without ever losing sight of the big picture.  

Jason credits his military background with his success as a lawyer. “I was a Ranger, Pathfinder, Jumpmaster, and other flashy titles like that, and at the time I thought I was just learning the art of war. I realized later that I was learning how to be intensely focused and determined in the most trying of circumstances, how to effectively and efficiently communicate, complex problem solving and relentless work ethic. When you apply those skills in the practice of law, you can take on any legal challenge and the most capable opposing counsel.”
