About Diana

Diana has demonstrated her expertise during her fourteen-year tenure on the Pierce County Superior Court Bench. She presided over a broad range of cases including criminal law, civil law, family law, probate, guardianship, landlord-tenant disputes, juvenile law, and mental health law. In 2009 through 2019, she served as a Pierce County Superior Court Commissioner, and was elected to the position of Judge in Department 7 in 2020. This experience makes Diana well-equipped to oversee any area of law.

Diana is a Pierce County native, and graduated from Fife High School. She went on to attend Pierce College, the University of Puget Sound, and the University of Puget Sound Law School (now Seattle University School of Law). Her first job was as a secretary to attorney Thomas Felnagle and attorney John McCarthy, both of whom later served as Pierce County Superior Court Judges.

Diana married her high school sweetheart, Larry.  Larry is a lifelong member of IBEW Tacoma Local 76, and also taught in the IBEW Electrical Apprenticeship Program for five years. Today, they live in Puyallup.

Diana worked as a lawyer in private practice, where she fought for the legal rights of her clients. Later, she was appointed to the Superior Court Bench as a Commissioner. As a Commissioner, she was dedicated to upholding the Federal and State Constitutions, and laws, in a fair and unbiased manner. Diana was known for her neutrality and served as a faculty member at the Washington State Judicial College where she taught new Judges and Commissioners the importance of being impartial decision makers, upholding the rule of law, and ensuring that all litigants had equal access to justice.

Diana is dedicated to assisting lawyers in meeting the challenges of serving their clients’ legal needs while upholding the rule of law. She currently acts as a liaison between Pierce County Superior Court and the Tacoma-Pierce County Bar Association. Diana has an extensive history of cultivating future leaders by providing mentorship programs and externships to law students in her Court.

Diana holds several important positions in the judicial system in Washington. With the Washington Superior Court Judges’ Association, she is the chairperson of the Probate Guardianship and Technology Committees, and a member of the Legislative Committee. In 2013, she was appointed by the Supreme Court of Washington to the Certified Professional Guardianship and Conservatorship Board (CPGC Board), where she served until 2023, eventually becoming the Chairperson of the Board. Currently, Diana is the Chairperson of the Outreach Committee for the Washington Supreme Court Disability Justice Committee, where she works towards improving access to courts for people with disabilities. Diana has also received recognition from the Office of the Staff Judge Advocate, I Corps, for her work as a liaison between JBLM and Superior Court, which has helped provide access to justice for active duty military personnel, their families, and veterans.

Diana’s experience, and dedication to fairness, equity, equal-access to the law, and her unbiased, ethical approach to her job on the bench make her supremely qualified to continue serving Pierce County as a Superior Court Judge.
