Andy Kim
Associate Pastor
Andy graduated from Northwestern University with a major in economics with the desire to make it “big.” Afterward, he started working in corporate America and realized God had a different plan for him. Responding to the call to ministry, he began seminary at Trinity Evangelical Divinity School in Chicago while serving as a youth pastor. In early 2015, he moved to San Francisco to serve at Radiance while finishing his Masters of Divinity at Fuller Theological Seminary. He has a heart for the city of San Francisco to see God redeem the broken and the lost. In his free time, he enjoys eating and exploring different places in the city with his amazing wife Jane. They're expecting a baby boy in the summer!
Diana Kim
Children's Ministry Director
Diana was born and raised in Orange County in Southern California. She graduated from University of California, Riverside with a major in Global Studies and studied abroad in Korea for a year during her last year of college. After coming back to the states she happened to pursue a career in teaching, which led her to move to San Francisco. Moving to San Francisco wasn’t something she had planned on and it was through coincidence she found out about Radiance. During her time in San Francisco Diana has been an afterschool program teacher, a bilingual para-professional, and a 1st Grade Korean Immersion teacher. She has transitioned from being a full time teacher to full time Children’s Ministry director. She hopes that her skills and experience as a teacher will help serve the children and families at Radiance and the Bay Area.
Sergio Gomes
Associate Pastor
Sergio was born and raised in Southern California. At the age of 20, he encountered the Lord and his life has never been the same since. A few years later, God called him into full time ministry. A year after finishing his undergrad work and working in sales, he pursued a Master of Divinity from Talbot Theological Seminary. He currently is ordained by the Evangelical Church Alliance. Sergio has been married for over 10 years to the love of his life Mi-hee.
Alexis Lee
Worship Director & Admin
Alexis was born and raised in Southern California. In early 2012, she felt the Lord lead her to move to the Bay Area and pursue music at Cal Berkeley. It was there that she first learned about Radiance and began serving on the worship team. Although she grew up very shy with little music background, worship has always been something she enjoyed being involved in. Over the summer of 2017, the Lord pressed upon her heart to leave her corporate job and move forward into full-time ministry. She hopes to continue to press into God’s calling for worship over her life and see great things happen for the city of San Francisco. In her spare time, Alexis really enjoys watching movies and TV shows, especially Food Network. She loves cooking, online shopping and spending time with her husband, Andres. Together they hope to faithfully serve the Lord and see God move through the Bay Area.
Mark Chun
Lead Pastor
Mark grew up in the East Bay but left to go to UC San Diego for college. There, he met his beautiful wife, Mira. After receiving his call into ministry, he gave up the pursuit of dental school but continued to work bi-vocationally as a research chemist in the biotech industry. He eventually enrolled at Talbot Theological Seminary where he graduated with a Masters of Divinity. Mark started Kairos Church in 2006 and served as the founding pastor for 5 years until sensing a call to return back to the Bay Area to start Radiance. In his free time, he loves to play golf and surf, go hiking, as well as spend quality time with family. He is a die-hard Bay Area sports fan and roots faithfully for the Niners, Giants, and Warriors!
Mira Chun
Women's Ministry Director
Mira is a San Diego native and met Mark during his college years. They have been married for over 20 years and have two beautiful children, Jeremiah and Carissa who have been with them every step of the way on this crazy journey of following God. Mira has a deep desire to see women healed from their past hurt and to experience freedom as they discover their identity and purpose in God. Her current focus is discipleship and inner healing as God leads her to empower and equip women in their faith journey. In her free time, Mira loves to go out and meet new people to hear their stories. She also enjoys her dates with Mark where you will often find them hiking somewhere in the city or enjoying coffee at one of the many cafes.
