Judge Marshall Ferguson was appointed to the King County Superior Court bench by Governor Jay Inslee in 2018.  Judge Ferguson assumed the trial department previously held by the highly esteemed Judge Helen Halpert, who retired from the bench. 

Prior to joining the judiciary, Judge Ferguson practiced law for 19 years, mostly as a civil litigator partner at the Seattle law firm of Williams Kastner.  He litigated a wide variety of commercial matters, particularly in the areas of real estate and aviation, representing clients in state and federal courts throughout the Pacific Northwest.  Between 2016 and 2018, he served as a judge pro tem at the Edmonds Municipal Court, learning under Judge Linda Coburn, who presently serves as a Judge on the Washington Court of Appeals.

Judge Ferguson has long been interested in attorney and judicial ethics, and is committed to developing and teaching rules of ethics that foster public confidence in the courts and judges.  Prior to becoming a judge, he was his law firm’s chief ethics officer and also served as a court-appointed hearing officer for Washington State Bar Association attorney disciplinary hearings.  Judge Ferguson now serves on the Washington Supreme Court’s Ethics Advisory Committee for judicial ethics and is the current chair of the Superior Court Judges Association’s Judicial Ethics Committee.  He has contributed to numerous Ethics Advisory Opinions, and has trained judges and court employees regarding a variety of ethics-related issues.  As a regular participant in the Judges In The Classroom program (now resumed post-Covid), Judge Ferguson enjoys teaching students of all ages about judges and the judiciary.

Since joining the Superior Court, Judge Ferguson has chaired the Court’s Dependency Committee, co-chaired the Court’s Budget Committee, continues to serve on both the Budget and Personnel Committees, and was the Court’s Lead Dependency Judge from 2021 until 2023.  Judge Ferguson frequently handles judicial settlement conferences in civil cases, including for dependency/termination matters, and welcomes settlement conference inquiries.

Judge Ferguson is a graduate of the University of Washington School of Law and Johns Hopkins University.  The seventh of ten siblings, Judge Ferguson’s hometown is Lopez Island, Washington, though he currently resides in the Northshore area with his wife and two daughters.  He is a private pilot with a lifelong passion for aviation.
