Billy and Teresa met in Waco, TX while on staff at Antioch Community Church and were married in July of 2005.  During his time at Antioch Billy was an active leader in over a dozen mission trips, church planting, college ministry, cell leadership, discipleship and outreach.  Billy grew up in Katy, but left in 1998 to go to Baylor University, where he wound up at Antioch.  The day they returned from their honeymoon in 2005, they packed up and drove to Portland, OR to plant a church through AMI where Billy served as the Lead Pastor.  In 2008, "The Door: Community of Faith" sent the Siehs out to Katy, TX in a response to God's leading and although they miss their friends in Portland, they are grateful to make new ones at Life Church.
