Mike Sereg

Associate Pastor


At the ripe age of 19, Mike started leading construction crews for his father's construction company, but always felt a tug on his heart to be a leader in the church. 26 years later, Mike answered the Lord's calling and became a commissioned pastor. In July of 2017, Mike became our associate pastor, implementing his passions in many different ways: evangelizing to people of all ages and all backgrounds, leading people to a relationship with God, meeting and welcoming new people, and leading men. Although he maintains a very busy schedule, he still finds time to ride his Harley, be with his lovely wife Dana, being a parent and grandparent, and taming his giant yet gentle Bernese Mountain Dog, Gia!

Kristy DeZwarte

Children's Director


"In His time" is a phrase that has been a big factor throughout Kristy's life. Growing up in Central, Kristy attended Iowa State and found herself shortly after working in Des Moines. While helping with children's ministry at her church in Altoona, Kristy discovered that, not only is she passionate about leading little ones, but she also desired a family and little ones of her own. In 2014, Kristy married her husband Ryan and now have two beautiful little boys, Rylee and Ryder. She loves helping at her husband's family farm, cooking, reading, traveling, trying new things, and being with her family!
