Mary E. Hershewe



Mary Hershewe navigates a broad range of complex product liability and commercial litigation matters, counseling clients through all steps of litigation in both state and federal courts. She concentrates her practice in litigation planning and management, multidistrict litigation, discovery coordination, depositions, motions practice, oral argument and trial preparation. Mary has been involved in numerous pharmaceutical and medical device litigations, including multidistrict matters. 

Mary is a member of the firm’s health and life sciences team, and the food and agribusiness team. Her industry skills also include app-based clients, toxic tort litigations and business disputes.

Mary frequently publishes and contributes to the Faegre Drinker on Products blog and client alerts. She has written on deposition and litigation hot-topics, and as well as other areas of interest to complex commercial litigation and product liability clients, including FDA regulations for medical and pharmaceutical clients, and the intersection of data privacy and product liability. 

In addition to having complex commercial and product liability experience, Mary also has experience with family law disputes and tax appeals.

Before joining the firm, Mary worked at another large firm focusing on medical malpractice, catastrophic torts and complex commercial litigation, where she managed all aspects of cases, from discovery, to selecting and consulting with experts and arguing dispositive motions. Her background in medical malpractice and catastrophic torts provides a strong and well-rounded foundation to solve the complex legal problems her product liability clients face.

During law school, Mary externed at the Missouri Supreme Court for former Chief Justice Richard B. Teitelman. Mary also competed in the National Mock Trial program, and co-chaired the Women’s Law Caucus Public Interest Auction, raising money for students engaged in nonprofit and public interest law. She was awarded the “Leader of Tomorrow Award” by Missouri Lawyers Weekly.
