A Strong Record of Service
Judicial Experience
Judge Diaz began his career in private practice, first as an associate at the international law firm Fulbright & Jaworski LLP in Houston, Texas, then at the litigation boutique in Seattle, litigating complex commercial and white-collar criminal defense matters.
Judge Diaz then spent a decade as Assistant United States Attorney at the U.S. Attorney's Office in Seattle ("DOJ"), where he helped found the office's Civil Rights Program and investigated and/or prosecuted a wide variety of civil rights matters.
In 2016, President Obama nominated Judge Diaz to be a U.S. District Court Judge for the Western District of Washington and in 2018, Governor Jay Inslee appointed Judge Diaz to the King County Superior Court, where he presided over approximately four dozen trials in all types of criminal, civil and domestic matters. He also served a term as the Chief Judge of King County’s Patricia H. Clark Children & Family Justice Center, and served on the Court’s Executive, Budget, Rules and History committees.
In 2022, Governor Inslee then appointed Judge Diaz to his present position on the Washington Court ofAppeals, Division I, where he has authored over 200 opinions in all types of matters.
