Koko was born in Taiwan and came to the United States when she was 16. As the oldest of 6 children, she was responsible for her siblings throughout their school years. She graduated from UC Berkeley with a Bachelors in computer science and began her career as a software engineer.

Along the way, Koko became progressively more and more involved with the API and LGBT community, first volunteering with API-PFLAG, API Wellness Center, Asian Pacific Sisters (APS), Self Help for the Elderly and the Asian Women’s Shelter as well as APLBN (Asian Pacific Lesbian Bisexual Network).

Koko is married to Margot Yapp (first in 2002, then again in 2004 and 2008) and they live in Oakland. Their daughter, Megan, was born in 2004, and they added a pet hamster, Pancake, in 2013. When she has any leisure time, Koko loves to oil paint, play tennis and golf, and continue to build a better community for LGBT people. Occasionally, she even develops software for her clients.
