Leadership and Staff

Oak Grove Christian Church is an Elder led, staff supported church. This means that the church has selected and elected men to “pastor” or “oversee” the church. The Elders empower the staff to do many of the day to day tasks of the church and the staff serves under the leadership of the Elders who serve under the leadership of Jesus. 

We also have Deacons and Trustees who help to take care of some of the needs of our congregation and building.

    "It is my desire to see as many people as possible brought to a saving knowledge of Jesus Christ."
