Mark was born into a military family and accepted the Lord as his personal Savior at a young age. When he was a teenager, he surrendered his life to full-time Christian service. He desired to be used of God on the mission field, but the Lord had other plans and directed his steps to serve as a program director at a Christian camp in northern Wisconsin after graduating from Pensacola Christian College with a Bachelor of Arts in Bible. The Lord used his ministry there to prepare him for future ministry opportunities.
In 2004, the Lord directed Mark and Sarah to a church ministry in New Jersey, where they served for more than three years in the music and Christian school ministry. In February 2008, the Lord brought the Davis family to serve at Berean. Since being here he has served as the assistant pastor and Woodlands Baptist Camp director. In December 2013, Pastor Davis earned his Master of Divinity degree from Liberty Baptist Theological Seminary. In August 2016, the church voted to call Pastor Davis as the Senior Pastor.
Mark is married to Sarah, and they have four children, Allen, Simon, Parker, and Lydia. Sarah serves along side Pastor Mark in the ministry and also serves in the church office.
