About us

This ministry was born in 2013 after Zac Linton received a vision from the Lord to go preach the gospel on the UC Berkeley campus. In addition to years of college ministry, Zac has had the privilege to travel to many other nations to declare the glorious message of salvation.


In the course of time, Overflow Ministries has grown into a gifted team from around the world, united for the purpose of bringing the gospel to the nations. It is affiliated with Luis Palau's Global Network of Evangelists and works with ministries and churches globally. Overflow Ministries is registered as a religious non profit in the United States.
