After working closely with a pastor who encouraged him to learn the importance of waiting on God, a passion awakened in him to live his life to please God, which eventually led him to Southlands.It is Mr. Duncan’s mission to raise up global leaders by first bringing each student to a saving knowledge of Jesus Christ and envisioning them to fulfill their God-given destinies.  His dream is to see students graduating with integrity and being agents of change in the world.
