The Westfalls, a missionary family of Artists in Christian Testimony International, are full time missionaries to North America. They work full time on the staff of The Extreme Tour. They are funded only by monthly supporters and gifters. They work to fulfill the vision God has given them, which is to reach out with the love of God to the counter culture in the cities and towns all over North America. 

Bobby's role is to serve as the North American Teams Manager for The Extreme Tour and Stacy works as the A&R Manager as well as the Prayer Cover team Manager. During the summer they travel with the East Coast Leg of the tour. 

They are based out of the Nashville, Tennessee area where they live with their 2 year old daughter Arabella Rayne.
