Katie practices in a wide variety of legal disciplines before both state and federal courts as well as arbitral tribunals. While her practice has primarily focused on the defense of Fortune 100 companies in pharmaceutical and medical device product liability litigation and environmental/toxic tort litigation, she also has experience litigating contractual and land use disputes, employment law matters, class actions, and product liability matters outside of the pharmaceutical context. Mindful of nascent trends, she counsels clients on potential liability arising out of emerging metaverse technologies. Beyond the trial court arena, Katie has seen many of her cases through appeal and engaged in public policy work, thereby gaining considerable experience at the appellate level.
