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.”


  • Won a rare trial award of more than $20 million in punitive damages against an insurance company in a Delaware case, alleging that the company’s refusal to cover legal fees for the insured’s litigation was bad faith.

  • Won a defense verdict for a joint compound manufacturer in a Delaware mesothelioma case with no alternative exposures to asbestos products by convincing the court to exclude plaintiffs’ general negligence and design defect claims, leaving only a failure to warn claim (against a defendant that had provided adequate warnings).

  • Prevailed on a summary judgment motion by convincing a Delaware court to apply the Pennsylvania statute of repose to the claims at issue, despite the fact that multiple Pennsylvania trial courts had refused to do so.

  • Devised and executed a 50-state strategy to protect a client’s privileged document that had been wrongfully obtained and widely disseminated by plaintiff attorneys.

  • Led a national discovery team in responding, over a two-year period, to 465 sets of written discovery requests including over 200 sets of document requests. The team produced documents in response to only 10 of those sets of requests; faced only six motions to compel documents and/or information; defeated two of those motions; and convinced plaintiffs to withdraw the other four.
