Meet Pastor Billy

Lead Pastor

Billy Lowe previously served as a Pastor at The Summit Church in Durham, NC for 5 years. He is married to his wife Allison and they have four children, Emma, Addyson, Elliot, and Keller.


Billy grew up in Central Florida and went on to play football at both Northern Illinois University and Georgia Southern University. He was a student at Reformed Theological Seminary in Charlotte where he worked on a Masters of Theology in Biblical Studies. His desire is finish his graduate degree at some point.


It was during his time at the Summit Church that God called him to plant a church. Years of sitting under the teaching of Pastor JD Greear and being a part of a “sending church” moved Billy and Allison’s hearts to plant a church. Through years of discernment, Billy came to the conclusion that it would be selfish to stay and not multiply the lessons he learned at the Summit Church. They believe that God’s church is his “plan A” and they want to give their lives to pastoring a healthy church in Alpharetta, GA. Billy is passionate about preaching the Gospel, seeing people come to faith in Jesus, and serving others.


City Church is also a part of the Summit Collaborative. This is a church planting network that has a vision of planting 1,000 churches in our generation. The Summit Network believes in a three distinctives: Gospel, Balance, and multiplication.
