Senior Pastor - John Sung
John has been with Redeeming Grace since the church's inception in the summer of 2017. He received his Bachelors of Science Degree in Economics at the University of Illinois in Champaign-Urbana and his Masters in Divinity at Moody Seminary. Prior to serving at Redeeming Grace Church, John served as the Executive Pastor at New Community Church, and also pastored for nearly eight years in English speaking congregations in Korean immigrant churches in Minneapolis, Minnesota.

Associate/Youth Pastor - Jacob Zeller
Jacob is a born and raised Hoosier who graduated from Wheaton College with a degree in Biblical and Theological Studies in 2017. After graduating, he went to Princeton Theological Seminary where he earned his Master’s in Divinity in 2020. He joined the staff of Redeeming Grace Church after completing seminary in the summer of 2020. Jacob’s passion lies in systematic theology and showing how the oft perceived esoteric discipline is, in actuality, excessively accessible and helpful to the everyday life of the Christian. Jacob feels exceedingly lucky and blessed to be able to serve God’s Kingdom at RGC.
While at Wheaton, Jacob met his wife Caris. They have been married since 2018 and had their first child, James Sungwook Zeller, in September of 2020. Caris has a Master’s in teaching and is a high school chemistry teacher at Glenbard East High School. Additionally, they have a yellow lab named Athos. They are roller coaster enthusiasts, having ridden 74 different coasters across the country. Their goal is to get to 200.
In his spare time, Jacob enjoys reading, writing, weight lifting, and any and all forms of sport. He is a life-long Chicago Cubs fan, and will forever remember November 2, 2016 with much joy.

Elder - Won Tchoi
Won grew up in Minnesota and moved to Chicago in 1995 after graduating from the University of Minnesota with a degree in Electrical Engineering. He has worked in the technology field his entire career. While he commutes to downtown Chicago for work in the Metra, unlike many, he enjoys the extended time on the train each day because it is some of the only time he has to himself.
Won has been an elder when Redeeming Grace Church since the church was formed. As an elder of the church, apart from the pastoral and spiritual care of the church, he is responsible for overseeing our community life ministries which includes our Community Life Groups, Food Team, and Welcoming ministries.
