Stephen E. Marshall

Marshall Stephen

Steve Marshall is a trial and appellate litigator who focuses on medical, scientific, and technology issues. Steve has experience in federal and state courts and has directed all stages of litigation, including as lead trial counsel, coordinating counsel, and settlement counsel. He has tried cases involving product liability, insurance coverage, intentional tort, premises liability, and catastrophic accidents. His participation on science and expert development teams in mass tort pharmaceutical and vaccine litigation has given him considerable knowledge in the areas of cardiology, neurology, immunology, and epidemiology.

Steve has participated in several months-long trials involving pharmaceuticals, medical diagnostic assays, and technology used by the financial industry. He has played lead roles in two recent MDLs and one consolidated mass action.  He has argued numerous appeals before the U.S. Court of Appeals for the Fourth and Eleventh Circuits, and before state appellate courts in Maryland and Pennsylvania.

Steve has tried to verdict and resolved several cases before the Court of Appeals of Maryland. He draws from his extensive knowledge of efficient, court-tested techniques to help petitioning parties overturn lower state court decisions and help respondents defend favorable rulings on appeal.
