Mark Zeiler

Lead Pastor

Mark spent his first 10 years out of college serving students and families as a Student Pastor in both Florida and Texas. After spending a few years as a Young Adult Pastor here in Austin and a church planting resident at Providence Church, he followed his call to plant Trinity Church. Mark loves the idea of building a church community that helps people follow Jesus in every area of life through the life and hope found in the gospel. You will likely see Mark around town at a great coffee shop, eatery, spring, or trail. Mark and his wife Megan are the parents of their children Harper and Haddon.

Grant Sather


Grant has been in full-time ministry since 2008, and most recently served as an Associate Pastor in Sioux Falls, South Dakota.  Mark called Grant in December 2015 to share with him about the prospect of planting a church in Austin, TX. Although Grant initially dismissed the idea, God began speaking over the next few months to both Grant and Alissa and confirmed in July of 2016 that God was calling them to raise support and move to Austin. The Sather’s arrived in Austin in November 2016 and now feel like they can call Austin home. Grant loves to play golf (or any sport!), read, grab drinks with friends or spend time with his family. The
Sather’s have two boys, Henry (4) and Harrison (1).
