Pastor Koehler
Pastor Ron Koehler serves as Grace’s administrative pastor and oversees the congregation’s multi-site ministry. He also has regular pastoral duties at the Grace-Tucson location. He grew up in Michigan, where his pastor inspired him to consider the pastoral ministry. He has served at Grace since 1993, after serving for two years teaching English, supervising the boy’s dormitory, and coaching at Martin Luther Preparatory School in Prairie du Chien, Wisconsin.
He and his wife, Debbie, have enjoyed living in Arizona and raising two sons here. The people at Grace are very special to them, and they consider it a privilege to have seen the Lord bless the congregation’s ministry immensely over the years.
Besides sharing the love of God in Jesus, Pastor Koehler enjoys his grandkids, a round of golf every now and then (his game needs a lot of work!), and the company of good friends around the grill.

Pastor SCHEueRLEiN
I was born in Minnesota in 1985 to Pastor Don and Amy Scheuerlein. A few years later, my father accepted a Divine Call to Calvary Lutheran Church in Thiensville, Wisconsin, where I grew up along with my 2 sisters and 4 brothers. Calvary Lutheran Church is now a part of Christ Alone Lutheran Church, a multi-site church in Thiensville and nearby Mequon.
I have had the pleasure of serving God’s kingdom in a few different areas. My vicar year was at Redeemer Lutheran Church in Tucson. After graduating from the seminary, I was assigned to Nebraska Lutheran High School (NELHS) in Waco, Nebraska, where I served as dorm supervisor, teacher, and coach. After 2 years at NELHS, I was assigned to St. Luke’s Lutheran Church in Grand Rapids, Minnesota. I have served the members of St. Luke’s for the past 6 years. Now I am excited for the next chapter to begin as I join the members of Grace, particularly in Vail and Benson.
