    I have practiced law for 27 years and have appeared before numerous judicial officers in nine counties. Additionally, I have collaborated with many judicial officers on various work groups, boards, and committees. I have yet to encounter a judge who works harder and invests more time in their work than Judge Diana Kiesel. Her outstanding commitment to preparation and passion for fairness make her an exceptional judge. I strongly endorse Judge Diana Kiesel for re-election.

      Judge Diana Kiesel brings clarity to her role as judge, often due to her lived experiences as a family law attorney and as a volunteer mediator. She knows that often the people who have a relationship need to be involved in the resolution of their disputes. As a judge she nudges and encourages parties to find their best solution. She has been a powerful partner and supporter of the work done at the Center for Dialog & Resolution.

        I renew my endorsement of a judicial officer I have found to be fair, personable and dedicated. Judge Kiesel truly embodies the best qualities of a good Judge and is beyond “highly qualified.”

          I was fortunate to work for, and be mentored by, Judge Kiesel for the first 10 years of my career. I saw her knowledge, skill, and integrity every day as she tirelessly represented her clients, and that dedication continued when she served as a Pierce County Court Commissioner for 10 years and then as Judge for the last 4 years. Judge Kiesel has the experience, knowledge, temperament, and dedication to serve the citizens of Pierce County. I highly endorse Judge Kiesel for another term as a Pierce County Superior Court Judge.

            I endorse Judge Kiesel’s reelection because she was a wise, fair and impartial judge when she oversaw the Dependency Court. Hopefully, her reelection will enable her to oversee Dependency Court again, in which families would, again, highly benefit from her rulings, and other parties as well.

              Pierce County is fortunate to have a jurist of Judge Kiesel’s caliber. She is a compassionate, even tempered, well-reasoned steward of the rule of law.

                I had the opportunity to watch Diana Kiesel as an acting court commissioner. In every hearing I observed she executed the law in a just and compassionate manner with a focus on meeting the best needs of the parties involved. It was often difficult, but she never failed to execute the law with compassion and respect for those that came before her. If re-elected I believe she will continue to be a fantastic Superior Court judge.
