In addition to her legal practice, Katie has been an active volunteer and has served as a member of the Washington State Bar Association Board of Governors and chair of the Washington Commission on Judicial Conduct, and is presently a member of the Council of the American Law Institute. In assuming the role of chair of the national Commercial Litigation practice, Katie succeeds Joe Mais, who has served in the role since 2008.

Karen, also based in Seattle, has been with Perkins Coie since 1999. She has practiced environmental law for more than 25 years and represents clients in project development, regulatory compliance and litigation matters under state and federal laws.
