Our Team

 Spencer Keroff

Lead Pastor

Pastor Spencer is passionate about the life-transforming Gospel of Jesus Christ! In fact, you might say 1 Corinthians 2:2 is his life verse: “For I determined to know nothing among you except Jesus Christ, and Him crucified.”

Before coming to serve at First Church on Easter 2013, Pastor Spencer served in a plethora of church ministries ranging from youth pastor to associate pastor to lead pastor (in Iowa, Colorado, and Minnesota). He holds a B. A. from North Central University in Minneapolis, and and a M. Div. at the University of Northwestern in St. Paul.

Pastor Spencer has been married to his wife, Lisa (the woman of his prayers and dreams), since July 14, 2001. They have 4 children: Chloe, Josiah, Layla and Liliana. The Keroffs homeschool their children, and strongly emphasize home discipleship in their marriage and ministry.


Roger Cox

Pastor Roger has been attending First Church since 3rd grade and counts it a true blessing to have sat under so many great pastors. Pastor Roger and his wife Connie have 3 grown children and seven grandchildren.

Pastor Roger has served the church in many different leadership roles over the years and is now the one overseeing our Mission’s ministry for the church. Pastor Roger received his diploma in Bible and Theology studies from INSTE Bible College in 2013.

Pastor Roger has a passion for discipleship and missions, wanting to see believers continue to grow in their relationship with Jesus throughout their life. As the pastor of Missions the focus will be on local and global outreach.
