Marcus and Simona Saint-Naylor have lived in King County for over 30 years. Currently they reside in the city of Sammamish with their children Bianca and Lucas, and their dog, Ziggy. Bianca attends Central Washington College while Lucas attends Cascade Elementary School. Simona has been a real estate agent for over sixteen years.

Marcus began his life as an orphan on the streets of South Korea. It was through the kindness and goodwill of his parents, Dorothy and William, and sisters, Chris and Jeanne, that Marcus was adopted when he was nine years old and brought to the United States. It was here that William and Dorothy, through their love and affection, taught Marcus the value of hard work, and instilled within him a desire to dedicate his life to public service.

Marcus is deeply committed to public service, and has served his entire career with the King County Department of Public Defense.  While working as a defender advocate, he has represented thousands of youths and adults in all the courts of King County.  Additionally, he has worked as a supervising attorney at all court levels, supervising dozens of attorneys to ensure that all citizens would be guaranteed of highest level of legal service from their attorneys.  Marcus’ commitment to public service extends beyond the courts through his service as a volunteer for the Neighborhood Legal Clinic, as a panel member to the KCBA Diversity Committee, and with many other community organizations.

Since 2012, along with his job as a supervising attorney for King County Defenders, Marcus has appeared as a judge pro tempore (in place of an absent judge) in King County District Courts, presiding over every type of civil and criminal calendar. Marcus is fair, respectful, and compassionate. Litigants will know that they have received a fair hearing and received a just result when a case is tried in his courtroom. With his experience, knowledge, and demeanor, Marcus is highly respected by fellow attorneys, prosecutors, and judges. His depth of experience and knowledge will result in the efficient and competent administration of justice.

Marcus will bring integrity, impartiality, empathy and 26 years of experience to the court. He will be an outstanding judge.
