J. Mark Martin is senior pastor of Calvary Community Church in Phoenix, a Calvary Chapel. Pastor Mark received a B.A. in theology from Pacific Union College in Angwin, California and for six years pastored in the Seventh-day Adventist Church. In 1982, the Adventist Church became indignant as Mark began to teach God's grace and he was forced to resign and was ostracized from the church.

The non-denominational church that Mark started in 1982 in a northwest Phoenix school band room has since grown into a fellowship of over 12,000 believers. In 1984 an invitation was extended by Pastor Chuck Smith of Calvary Chapel, Costa Mesa, California to join the Calvary Chapel Fellowship of churches.
