Ryan Crossley was raised in Buenos Aires, Argentina, as a missionary son. At 18 years old, he immigrated to the United States to study at Indiana Bible College (Indianapolis, IN), graduating in 1998. He subsequently served as an assistant pastor (1998-2001). During this time, he met his wife, Amy, and they married in December 2000. In 2001, they traveled as international evangelists, serving for four years until finally founding Iglesia La Roca in March 2005. Since then, Iglesia La Roca has grown to a membership of over 850.

Under Pastor Crossley's supervision, growing daughter churches have been established in Ft. Myers, West Palm Beach, Hialeah, Bonita Springs, and Naples, with two more cities to come. The Rock Church and Pastor Crossley have been tremendously used by God to promote revival on an international level through a powerful cell movement and a highly effective leadership training system.
