Adam was born in the heart of Missouri, but he grew up in Oklahoma City. During his sophomore year of college at Oklahoma State University, a local college minister visited his fraternity house and shared the gospel with him using the "bridge" diagram. The Lord opened his eyes to the truth of the gospel and his need for a savior and Adam became a Christian. Shortly thereafter, Adam strongly desired to minister in the local church. 

Upon graduating college, he moved to Denton, Texas to pursue a pastoral internship program, where he met his wife Aly. Adam and Aly got married in 2013 and spent five years in Louisville Kentucky, where Adam finished the Master of Divinity degree and began the Doctorate of Philosophy in Systematic Theology while Aly taught Spanish and continued her studies in Education. Currently, Adam is inching closer to writing his dissertation and is hoping to contribute to conversations in Christology and Trinitarian theology. 

Adam has served as the teaching pastor at Emmanuel Bible Chapel since September of 2018, just around the corner from Liebenzell USA. His passion in ministry is preaching and teaching the Scriptures, as well as discipling others in the local church to do the work of the ministry.
