Prior to turning his life over to God, David Graham was a successful business man owning a construction company with offices in several U.S. cities as well as having played on several professional golf tours.

After turning his life over to God, David was on fire for God. He and his wife Melinda started an Over Comers Ministry in Georgia to help people with drug and alcohol addictions. The ministry became so successful that members of the Law Enforcement community would refer people to the ministry. The Over Comers Ministry is still going strong today.

In 1999, David followed the call of God and packed up his wife and daughter and moved to Las Vegas, Nevada. In 2000 David founded and became the Senior Pastor of Christian City Church Las Vegas. After being open for just over 2 years, the church was recognized by both City and State Official's for it's rapid growth and work in the community.

After he received the initial call on his life David embarked on a mission to learn everything he could. This mission has resulted in his earning a Bachelors Degree from Beulah University and both a Masters Degree and a PhD from Vision International. He is currently working on a Master of Divinity (M.Div) degree from Southwestern University.

In late 2007 Dr. Graham felt God was leading him in a new direction so he made the tough decision to close the church he had founded and concentrate on spreading the Gospel as Jesus had commanded in Mark 16:15

"He said to them, “Go into all the world and preach the gospel to all creation."
