In 1982, Heitzig began a home Bible study that eventually grew into Calvary of Albuquerque. In 2009, Calvary of Albuquerque was listed as one of the 15 largest churches in America, with an average weekend attendance of 13,000. In November 2018,
CBS News listed Calvary Chapel of Albuquerque as the 22nd largest
megachurch in the United States with about 16,830 weekly visitors and more than 13,000 followers on
Facebook. After a brief pastorate in San Juan Capistrano (Ocean Hills, 2004-2006), Heitzig returned to Calvary of Albuquerque as senior pastor in 2006, following the resignation of the previous pastor, Pete Nelson. Heitzig serves on several boards of directors, including that of
Samaritan's Purse. He also serves as Associate Professor of Pastoral and Biblical Studies at
Veritas International University. ==Education==
