Rev. Dr. John (Hans) and Gretchen Trinklein serve the Lord in Seoul, South Korea. Hans teaches at Luther Theological University and Luther Seminary. He also works with LCMS’ partner church, the Lutheran Church in Korea (LCK), helping them with their strategic vision and planning, with church planting and with continuing education for their pastors.

Hans’ hometown is Racine, Wis. He calls Olive Branch Lutheran Church, Okawville, Ill., his home congregation. He received a Bachelor of Business Administration degree in public accounting from Hofstra University, Hempstead, N.Y. He also received a master’s degree in apologetics from the Simon Greenleaf School of Law, Anaheim, Calif. (now known as Trinity Law School, Santa Ana, Calif.). He acquired his Master of Divinity and a Ph.D. in systematics from Concordia Seminary, St. Louis. Before serving in South Korea, Hans worked as a public accountant; he taught accounting at three different universities in southern California; and he served as pastor first at Zion Lutheran Church, Pierce, Neb., and, most recently, at Olive Branch Lutheran Church, Okawville, Ill. Hans’ hobbies include woodworking and spending time with his family.

Gretchen was born in Whittier, Calif. She calls Olive Branch Lutheran Church, Okawville, Ill., her church home as well. She received a bachelor’s degree in liberal arts from Christ College, Irvine, Calif. (now known as Concordia University, Irvine, Calif.). Over the years, she has served as a Lutheran preschool teacher, a substitute teacher, a nanny and a homeschool teacher to her children. Gretchen enjoys sewing, making cards, guitar, calligraphy, drawing, biking, hiking, art and music. Hans and Gretchen have four children – Jael, Abigail (Abi), Michael (Mike), and John – who join them on the mission field.


Please pray Colossians 1:9-12 over the Trinklein family.  

Please pray for wisdom and creativity for Hans as he teaches English and theology classes at Luther University.  

Pray also for his students—that they will be eager to learn and also be able to grasp and retain the material Hans teaches them.  

Ask God to enable the whole family to be faithful and fruitful stewards of their time, talents, and resources.  

Ask God to…

• protect us (in body, soul, and spirit),  

• continue to bless our relationships within our family and in our communities, and 

• enable us to be bold and courageous witnesses of His redeeming love.
