Pastor Sonja Gerstenberger joined the St. Andrew’s ministry team in March 2021. She is passionate about making the love of God in Jesus known to the world through ministry, service, and relationship.  Pastor Sonja has her B.A. from Wartburg College in English education and is a 2020 graduate of Luther Seminary’s MDiv Distributed Learning program. Pastor Sonja’s ministry is informed by careers in education, human resources, communication, and finally lay ministry. She served for seven years as faith formation director in an ELCA congregation, where she heard and answered the call to ministry. Pastor Sonja and her husband, Scott, have three children (Lucas – 2006, Nikki – 2008, and Analise – 2010) and most anything that can be considered a hobby or pastime involves caring for or spending time with them.
