The Role of Elder

The ministry of Geist Community Church is under the direction of the Lord Jesus Christ working in and through the elders. The elders are the primary decision-making body within the church, and make their decisions based on individual and corporate leading by the Holy Spirit, scriptural insight, carefully assembled facts, and input from the members.

The responsibilities of the elders are:
  1. Teaching/preaching biblical truth
  2. Modeling Christ-like behavior
  3. Maintaining doctrinal purity
  4. Leading the congregation in cases of church discipline
  5. Overseeing financial matters
  6. Praying for the flock

Matt Walker

Elder | Senior Pastor

During his childhood years in northern Indiana, God opened Matt’s spiritually blind eyes and led him to repent of his sin and believe in Jesus who is the way, the truth, and the life. (John 14:6) After graduating from Purdue University with a degree in Mechanical Engineering Matt thought he was heading for an engineering career but God had other plans for his life. While serving as a campus pastor intern for a local church in Lafayette and traveling to England on two separate mission trips God changed Matt's heart from pursuing engineering to vocational Christian ministry. In 2005 he graduated from Dallas Theological Seminary with a Master of Theology degree and has since served as adjunct faculty at a Bible college and as both an associate and senior pastor of churches in Texas, Iowa, and Indiana.

In 2009 Matt answered God’s call to become the senior pastor of GCC.  He and his wife, Anna, have been married since 2002 and have a son named Grant and a daughter named Grace. Matt's passion in ministry is to reach the surrounding community and the ends of the earth with the Gospel of Jesus. He is a dynamic teacher and communicator of God's Word who strives to equip believers and train other pastors/leaders so that they may, in turn, teach others to be rooted and built up in Him. (Colossians 2:7)  Matt enjoys spending time with his family, and reading about early church reformers like Zwingli, Calvin and Knox - and he can usually be found building something outdoors.

John Moore


Over forty years ago two men asked me “If you were to die tonight, would you go to heaven?” I honestly didn’t know the answer to this question. Having grown up in the church, I had assumed “yes” for all my life, but I realized at that moment that I only had a working knowledge of God without a personal relationship with Him. The men shared with me the truths of Ephesians 2:5–10, how I was dead in my sins and how Christ came so that I might have my sins forgiven and be made spiritually alive in Him. God showed me that I really needed a Savior to be made spiritually whole and to be in right relationship with Him, and from that point I trusted in the Gospel. Since then, I’ve desired to be like David, a man after God's own heart (Acts 13:22) who seeks refuge in Him alone.

I have been blessed with my godly wife Roselyn and my three Christian sons: John, Bryan and Adam—who are now leading families of their own. Speaking of, God has also blessed me with 11(!) wonderful grandchildren! Since I moved here from Colorado, I have been blessed to serve Geist Community Church in the capacity of elder, community group leader, and general get-things-done person.

Sean Gilbertson

Elder | Assistant Pastor

Sean grew up in Indianapolis and was convicted of his need for a Savior early in life through the spiritual leadership of his parents. Sean served with his family as missionaries in southern Arizona during his high school years and returned to Indianapolis (and GCC) after graduating from Grace College in 2007 with a degree in Graphic Design. In 2009 Sean married his wife, Kristine. They've been involved at GCC in various capacities such as leading the youth group, hosting community groups, and discipling individuals.

In 2015 Sean left his secular graphic design job and began working at GCC as the Administrator of Technology and Communications. He also began serving as an Elder in 2017. Sean began his role as Assistant Pastor in 2021.

Sean and Kristine have two sons. As a family they enjoy mountain biking, rock climbing, paddleboarding, reading, and working on projects together.

Dustin Phillips


Dustin grew up in the countryside near Clayton, Indiana, surrounded by fields of corn and soybeans. His parents helped him understand at a young age that he needed a Savior, and that he needed to repent of his sins and put his trust in Jesus to save him. Since that time, God has been faithful to grow him “in the grace and knowledge of our Lord and Savior Jesus Christ” (2 Peter 3:18), teaching him how he should abide by the Lord’s commands laid out in His Word.

After graduating from Purdue University in 2016, Dustin moved to the northeast side of Indianapolis, and soon after began attending GCC. He has involved himself at GCC in several ways, previously serving as the Support Deacon (aka “The Chair Shepherd”) and currently serving as a pianist in the music team. He first met his wife, Kristen, when they both showed up to volunteer as ushers at an Indianapolis Symphony Orchestra concert. In their free time, they enjoy playing music, hiking through Indiana’s state parks, and baking any dessert with a substantial amount of chocolate.
