Judge Trisha J. Hirashima

Judge Trisha J. Hirashima serves on the Placer County Superior Court at the Santucci Justice Center, having been appointed by Governor Gavin Newsom on June 3, 2022. She received her legal education at the University of California, Davis School of Law. As a Newsom appointee, she joins the bench as part of a cohort of judges selected during a period when the Governor emphasized diversity and professional accomplishment in judicial appointments. Because no ruling analyses, attorney observations, or ingested content are currently available in this profile, no patterns in her judicial decision-making, courtroom management style, or substantive legal preferences can be documented at this time. Attorneys should treat the guidance below as baseline preparation grounded solely in her verified biographical and appointment data, and should actively seek firsthand accounts from colleagues who have appeared before her in Placer County.

Given the absence of ruling data or attorney observations, no evidence-based tactical guidance specific to Judge Hirashima's decision-making patterns can be provided. Attorneys should apply standard best practices for appearing before a relatively new appointee: present arguments with clear legal authority, organize filings meticulously, and avoid assuming familiarity with local Placer County informal customs that a longer-tenured judge might have established. As a UC Davis School of Law graduate, Judge Hirashima received training at a California-focused institution known for public interest and practical legal education, but no specific doctrinal preferences or argument styles can be attributed to her based solely on that credential. Attorneys should monitor Placer County Superior Court dockets for emerging patterns in her rulings and consult colleagues who have recently appeared before her at the Santucci Justice Center.
