“Judge Kathy Han’s staunch advocacy for service and volunteerism has greatly influenced her participation and leadership in many endeavors. She has hosted numerous Vietnamese radio and television talk-show programs to educate the public on law and was included in ‘The Vietnamese American Heritage Foundation’s Oral History Project’ which detailed the hardships and successes of the first wave of Vietnamese refugees, amongst many other recognitions.
