Pastor David Landry came to know the forgiveness and love of Jesus Christ during his senior year at Maryvale High School in Phoenix, Arizona. He felt the Lord's call on his life shortly after his conversion and began attending Grand Canyon University. It was there that he met Tot Marshall, who became his wife in April, 1972. They have two adult children, Eric (who lives in Texas with his wife Sarah and their children) and Judy (who lives in Tennessee with her husband Mohammed and their children). 

    Pastor David was ordained to the ministry in 1978 while serving as Worship and Youth Leader at Greenway Baptist Church in Phoenix, AZ. After serving for many years in lay ministries, part-time staff positions and as full-time assistant positions in both denominational and non-denominational churches, David and his family became involved with Calvary Chapel of Sierra Vista, Arizona in 1988.

    What began as very involved lay members of that fellowship was soon changed as David was asked to become an Assistant Pastor. After serving in that position for about three years, David and Tot felt the Lord's direction to begin a verse-by-verse Bible study in the Casa Grande area. In June of 1991, the Landry family moved to Casa Grande to begin Calvary Chapel of Casa Grande.
