Our story

Bill & Lynne Themelaras and Adam & Tara Stewart have been friends for a long time. They also served together on the pastoral staff of Covenant Church of Pittsburgh for 7 years. Bill was a member of the executive elder team and pastored several areas of ministry as well as being a worship leader. Lynne served as the Director of Children's Ministry and the Director of a daycare center. Adam & Tara were youth pastors of the large inner city ministry and Tara was also a worship leader at the church.  

In 2010 they heard the call of God to plant a church and with the support of their pastor, Bishop Joseph Garlington, they began the adventure of prayer and preparation to pursue this vision.  

In the summer of 2011 it became clear that God's plan was to plant in the Columbus, Ohio area. After a three day trip of prayer and driving all over the area on a spiritual journey, they had a God encounter in Westerville and they knew it was the city to pioneer a new church.

In the fall of 2011, both families relocated to central Ohio to make the dream of Oasis City Church become a reality. After settling in and enjoying a quiet first Christmas in Ohio, they started prayer and worship services in their homes. That summer spawned several preview services and Oasis City Church officially launched on September 9th, 2012.
