RockPile Leadership

Casey Zimmerman 

Lead Pastor

Casey has a passion to proclaim the Word of God without compromise. He desires above all things to see those in his care grow into obedient followers of Jesus Christ. During his time in ministry, Casey served in several pastoral roles in Beaumont, Texas, including lead pastor, followed by six years of living on the mission field in West Africa. He came to the Texas Hill Country during the COVID pandemic and stepped into the Lead Pastor role at RockPile Church in January of 2022.

Casey has a Biblical History and Theology degree as well as an advanced degree in Human Services Management with a focus on counseling. His prayer for RockPile Church is to glorify God above all things, to proclaim the saving message of the Gospel to all the world, to make disciples who will make disciples and to create a culture of Agape love in the body that fulfills Jesus' command to His disciples to love each other as He (Jesus) has loved them (John 13:34-35).

He has been married to the love of his life and best friend, April, for over twenty-five years and they have been serving in ministry for over twenty-three years. They have two wonderful children, Jordan and Ryan. Together, they love to hike, read, play board games, watch cheesy movies and spend time exploring new places. Casey also loves all things C.S. Lewis, Star Wars and has read the full Dark Tower Series. Lastly, Casey loves his Houston Astros and is a long suffering, die-hard, Dallas Cowboys fan.

Ben Henderson

Worship Director

Ben has been a member of the RockPile Worship Team since the church started in 2014. He stepped into the role of Worship Director in the Summer of 2023.

Brett Kline

Director of Youth Ministry

Bret has been a part of youth ministry since he came to know Jesus as a Junior in High School at Magnolia Bible Church. He quickly desired to serve as a Junior High Youth Leader and share the Good News of the Kingdom of God.

Bret has been involved in several ministries throughout the years: MBC Youth, Skate Ministries, YoungLife Magnolia, Camp Peniel (in multiple positions), YoungLife Marble Falls and RockPile Youth, where he has been serving since 2018. He stepped into the role of Youth Director in February of 2022 with his loving wife, Zoe Kline.

Bret enjoys spending time with Zoe and Whiskey (his dog), skateboarding, camping and drinking coffee. He loves the creative and intentional aspect of God and looks to reflect that in his art and illustrations, which can be found on display at Numinous Coffee Roasters. This is a big part of how he has connected with the Marble Falls Community over the years.

His goal for the youth ministry is that our youth would look to Jesus as the author of wisdom and to let Him illuminate the way for them to navigate through this life and to light up this ever so dark world. He works closely with the other Youth Directors in the Marble Falls and Burnet area to show our youth how God is so much bigger than RockPile and to see a unified community that goes beyond these four walls.

Former Pastor - Matt Netzer 

March 11, 1977 - January 8, 2021

Founding Pastor

Matt passed away on January 8, 2021. He is now worshipping at the feet of his Heavenly Father.  He leaves behind Sarah, his wife, along with Lucy and Micah, his children. He will be deeply missed.

Matt epitomized Matthew 16:24-25, “If anyone wishes to come after Me, let him deny himself, and take up his cross, and follow Me. For whoever wishes to save his life shall lose it; but whoever loses his life for My sake shall find it.” Matt sacrificed everything for his calling as a messenger of the gospel of salvation, the “Good News”.

Matt was married to the love of his life, Sarah, and they have two kids, Lucy and Micah, who helped build RockPile Church and are active in the kids and student ministries.

Matt graduated from Southwestern Assemblies of God University in Waxahachie, TX and began pastoring in 1999. He loved Jesus, Texas, being on the lake, good music, drinking coffee, the outdoors, and old cars.
