David Sieplinga (M.Div) - Interim Lead Pastor

David Sieplinga “retired” in September of 2015 as the Pastor of Bethany Church, Muskegon.  He graduated from Calvin College (B.A.), did postgraduate work in philosophy at Columbia University and New Testament Studies at Union Seminary (NYC) and received an M.Div. degree from Calvin Theological Seminary.  He has served core city churches in New York (Harlem), Omaha, Grand Rapids, Chicago, Kalamazoo, Indianapolis and Holland, with both the Christian Reformed Church and the Reformed Church in American.  He was the lead pastor in two new core city church starts in Indianapolis and Holland and most recently served as an interim pastor at River Terrace CRC in East Lansing.


David is the husband of Terri, and together they have seven adult children and eight grandchildren.  He is an avid reader, a big fan of jazz and traditional Gospel music, enjoys playing pinochle, needs to exercise more and eat less and struggles to find a healthy balance between doing and just being.  He tries to remember that angels can fly because they take themselves so lightly.


AJ Gretz (M. Div.), Minister of Witness and Community Life

AJ is the Pastor of Witness and Community Life at Third CRC in Kalamazoo, MI. After spending two summers working at a Christian summer camp, he was ruined for anything other than a “Jesus job,” which led to a stint in campus ministry before getting an M.Div at Calvin Seminary. He is married with three children, and in his sliver of free time he enjoys running, biking, reading, complicated board games, and pinball.

Joy Koning

Joy Koning, Worship Coordinator

Joy Koning has served as our Worship Coordinator since July 2007.  Joy has been a church organist and pianist for nearly forty years, and is a published composer.  She has a passion for worship planning and is intentional about involving young children, youth, and adults in worship leadership and participation.

Joy's goal is to assist the pastors in crafting a morning worship experience that is thematically unified, and flows naturally from one element to the next.  Joy draws from the best congregationally friendly music from many genres - from psalmody and classic hymnody to global songs to gospel, to liturgical folk, to contemporary songs.  Heartfelt and God-glorifying singing by the assembled congregation is a priority at Third Church, whether accompanied by the organ or other instruments.
