I am a retired judge from the Superior Court of California, County of Riverside. I was the first Asian/Korean-American to attain that position. I served from 2008 to 2021 in the civil, family law, and criminal divisions.

Since August 2021, I have been a mediator, arbitrator and private judge/referee with JAMS, the largest provider of private alternative dispute resolution (ADR) services. To find out more about my work with JAMS, visit the JAMS website or see their video of My Story.

JAMS is committed to diversity, equity, and inclusion. It’s a value we share. I’ve participated in statewide work groups to address bias in jury selection and pretrial reform, and I’m a member of the Riverside Superior Court’s Committee to Eliminate Bias & Promote Equal Justice.

I love to teach. For years, I’ve taught judges and lawyers technology, evidence, and ethics. I frequently teach law students about evidence and trial advocacy. Before I became a judge, I taught sexual assault investigators and prosecutors about interviewing children and investigating child sexual abuse. I’ve taught a few people how to program computers.
