Erin F. Tatman represents clients on professional liability and complex commercial litigation matters. She helps healthcare providers, lawyers and law firms, corporations and other organizations evaluate difficult cases, develop practical strategies, and defend against claims involving significant exposure, whether through favorable early resolution or trial. Clients turn to her for matters that require careful judgment on technical, scientific, and medical issues as well as courtroom readiness. A chemist by training, Erin is comfortable dissecting technical evidence and expert opinions and translating that analysis into clear positions for clients, judges, and juries.
