Charles was born into a nominal Buddhist family in South Korea. He lived in spiritual brokenness and darkness, but God graciously saved Charles during his time in college. After graduating from Korea Medical School, he met Sarah, who was from Chicago. They were married in 1996 and served together in campus ministry in the Chicago area.

Upon completing medical training in Chicago and New York, Charles & Sarah moved to Minnesota in 2005, where they continued serving college students. God eventually led them to Bethlehem, and they became members in 2015, serving in a variety of roles within the church.

Charles is a family physician of North Memorial Hospital, working in their downtown Minneapolis clinic. He enjoys biking and hiking. His life verse is found in the words of Jesus in John 8:12: “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.”

Charles & Sarah live in St. Paul. They have four children and two dogs.
