Jeremy Wissink

Pastor of Student Ministries


Jeremy has been Pastor of Student Ministries since 2012 and loves what he does because he gets to do two of his favorite things on a regular basis: encourage students to pursue Jesus and play lots of games! It is a privilege for him to be a part of the spiritual growth of students as they understand the truths of God’s word, live out their faith in Jesus on a daily basis, and share Jesus with those around them. Jeremy graduated from both Grace University and Dallas Theological Seminary. During those years he grew in his love for God’s word and for people and is committed to bringing those two passions together in his life and ministry.
Jeremy is blessed with his wonderful wife Rachel, and two sons, Elliot and Seth. He loves living life with them. In his free time,  he enjoys outdoor activities, playing games, playing and watching sports, and playing and listening to music.
