Judge R. Glenn Yabuno

Judge R. Glenn Yabuno has served on the San Bernardino County Superior Court since his appointment by Governor Arnold Schwarzenegger on December 16, 2010, making him a long-tenured member of the bench with over a decade of judicial experience. He earned his law degree from Santa Clara University School of Law. His tenure spans significant institutional developments within San Bernardino County Superior Court, including court operations during the COVID-19 pandemic and the expansion of the Probate Division at the Fontana Courthouse, both of which he has been publicly associated with in news coverage. A April 2024 Daily Journal profile described Judge Yabuno as a 'Multitasker,' a characterization that reflects his involvement across multiple court functions and administrative matters within the San Bernardino County court system. This public profile suggests a judge who is engaged in the broader operational and administrative dimensions of the court, beyond individual case management. Because no ruling analyses, attorney observations, or ingested content are available at this time, the behavioral and jurisprudential profile of Judge Yabuno cannot be characterized with specificity. Attorneys appearing before him should conduct independent research into recent rulings and seek peer input from practitioners with direct courtroom experience before this judge.

Given the absence of ruling data and attorney observations, attorneys cannot rely on documented behavioral patterns to tailor courtroom strategy. The only concrete data point bearing on judicial temperament is the 'Multitasker' characterization from the Daily Journal in April 2024, which suggests Judge Yabuno manages a broad and varied docket. Attorneys should be prepared for a judge who balances multiple responsibilities and values efficient, well-organized presentations that do not waste court time. Judge Yabuno's long tenure since 2010 means he has presided over a wide range of matter types and has developed institutional familiarity with San Bernardino County court procedures and local rules. Attorneys should demonstrate thorough knowledge of local rules and standing orders, as experienced judges with long tenures on a single bench frequently have established procedural expectations. Checking the San Bernardino County Superior Court website for any published standing orders or courtroom-specific rules for Judge Yabuno's department is essential preparation. Attorneys with prior appearances before Judge Yabuno should be consulted directly, as peer intelligence is the most reliable source of actionable guidance given the current data limitations. Prioritize obtaining firsthand accounts from colleagues who have litigated in his courtroom.
