Biography
Maureen helps companies and individuals resolve complex disputes and legal issues. A seasoned litigator and trusted adviser, she handles high-stakes disputes from first assessment through resolution, with extensive experience in natural resource and environmental matters, Indian law, contract and trade secret disputes, and litigation involving fiduciary duties.
Colleagues and clients rely on her to step in quickly, take ownership of the problem, and bring structure and judgment to matters that are already moving fast.
Maureen’s approach to litigation is pragmatic and risk focused. From the outset, she works with clients to define objectives and assess exposure candidly. She guides clients to map out realistic paths forward — whether that means positioning a case for early resolution or preparing to litigate through appeal. Throughout a matter, Maureen helps clients weigh not just potential outcomes, but cost, time, stress and the value of finality.
In court, Maureen has handled matters at both the trial and appellate levels in state and federal forums, including the Ninth Circuit and the Washington Court of Appeals where she clerked. Maureen is also well-versed in Alternative Dispute Resolution forums, such as mediation and arbitration. She is admitted to practice before the U.S. Supreme Court.
Environmental
A significant portion of Maureen’s work involves disputes with an environmental or regulatory dimension. She regularly handles contaminated-site and natural-resource matters, brownfields redevelopment, water issues, and agency enforcement and compliance proceedings, working closely with clients seeking to navigate the local, state, and federal regulatory framework.
Her practice also includes administrative and health-and-safety matters that unfold outside traditional courtrooms but carry equally high stakes. These issues are not treated as specialties in isolation, but as part of an integrated litigation practice shaped by regulatory realities.
Indian Law
Maureen is Chair of the firm’s American Indian Law Practice Group. Her work in this area focuses on disputes involving jurisdiction, sovereignty, and treaty rights, often at the intersection of tribal, state, and federal authority. She represents tribes, tribal enterprises, and non-tribal entities navigating those boundaries, bringing a litigation mindset to matters that demand both legal precision and cultural awareness.
