Pastor Mark Warren

I'm excited to welcome you to our church! I pray you will be blessed in attending and getting to know our people as we share Christ’s love with you.
God is our Creator and desires a special relationship with His creation through the redemptive work of His Son –and that means God loves you! We are made to worship God, and we invite you to join us in serving Him together and sharing His love with our community.


I grew up in small-town-ville in the middle of the corn fields of Ohio while my wife Darcie grew up in a bustling suburb just north of Indianapolis. In God’s good providence, we met at Cedarville University and married a year later. (That was last century, folks; it was May of 1999!) God has added five children to our home: two boys and three girls. I studied at Grand Rapids Theological Seminary for my master’s degrees, and Darcie has undertaken the role of home educator for the children. we have had the privilege of serving churches in two other locations before coming to Grand Heights in March of 2022.


All along the way, God has been our Guide and Friend, our Provider and most worthy of our praise. We’re glad to follow Him in His leading of our family and to see how He will guide us in ministry here at Grand Heights. Truly the Lord is our portion as we have put our hope in Him. Great is His faithfulness!
