Anne Marie Seibel enjoys pulling together the moving parts in multi-forum or multi-plaintiff, high-stakes litigation. In these cases, she partners with her clients to approach the challenges of litigation in efficient and creative ways. For many years, she has used these skills to help a major facilitator of online travel reservations respond to cases across the country. In 2017, she served as lead trial counsel for this client in a two-week trial securing a defense judgment. The New Hampshire Supreme Court upheld this result after Anne Marie’s argument before the court. In prior litigation she played a central role advising HealthSouth Corporation as it defended and prosecuted claims relating to a massive accounting fraud perpetrated against it by corporate officers. That litigation resulted in a $2.8 billion verdict against the company’s former CEO and a $100 million settlement with the company’s former investment bank. Her practice has taken her to trial in venues as diverse as Alabama state and federal courts, New Hampshire state court, AAA arbitrations, and the Tribal Court of the Poarch Band of Creek Indians.
Nationally, Anne Marie served as the 2023-2024 chair of the ABA’s Litigation Section. For the 2025-2026 bar year, she is serving on the ABA Section Officers’ Conference Executive Committee as member-at-large. Other leadership roles have included serving as an elected member of the Litigation Section’s Council, managing director, co-chair of the Membership and Marketing Committee, co-chair of the Regional Meeting Committee, liaison to the ABA Commission on Women in the Profession, and co-chair of the Woman Advocate Committee. Anne Marie remains active in the ABA Section Officers’ Conference.
