Clergy
The Rev. Zac Koons
Rector
Fr. Zac accepted the call to be the Rector of St. Mark’s in July 2018. He was previously the Associate Rector at St. Richard’s in Round Rock. He attended Wheaton College and Duke Divinity School. Zac was born in Indiana, grew up in Arkansas, and is still surprised that he’s ended up in Texas—and still more that he loves it. On a day off, Zac likes to ride his bike. To blow off steam, Zac plays soccer and guitar. He’s a passionate supporter of Duke basketball, Arsenal Football Club, and tacos. He’s married to Anna, who works in global health, and they have a son, Laurie, and two crazy dogs, Watson and Hugo.

The Rev. Zoe Cordes Selbin
Curate
Rev. Zoe joined St. Mark's as a curate in July of 2024. Zoe grew up just 30 miles up the road in Georgetown, graduated from Southwestern University, and then spent five years working in marketing before discerning a call to ministry and attending seminary at Duke Divinity School. While at Duke, Zoe became particularly interested in liturgical studies and theologies of suffering. You can usually find Zoe cooking and baking, taking long, lazy walks while listening to podcasts, going to shows, reading, eating queso anywhere it can be found, or needlepointing in a patch of sun.
