Katie Callaway was born and raised in High Point, North Carolina. Katie’s educational pursuits began at Roanoke College where she majored in Religious Studies, graduating magna cum laude and receiving entry to Phi Beta Kappa honor society. Upon graduation, she completed two graduate programs. At Wake Forest University School of Divinity, she completed her Master of Divinity and at Emory University, she completed her Master of Theology. It was during her time at Wake Forest that Katie met John and shortly thereafter, they married. 

She has served churches in North Carolina, Maryland, and Georgia. Most recently, she served as Co-Pastor alongside of John at First Baptist Church, Savannah, GA. There, she focused on creating and nurturing opportunities for education and spiritual formation in both large and small group settings.  

Katie has worked in churches throughout the southeast, primarily focusing on spiritual formation. She feels called to help congregations develop vibrant spiritual formation programs and practices by walking alongside people as they embrace holy curiosity and faith exploration. In her role as Co-Pastor, she is most excited about helping Christian Temple deepen its practices around spiritual formation and worship. 

An avid reader and writer, Katie is completing coursework in her Doctor of Ministry in Creative Writing as Public Theology at Pittsburgh Theological Seminary. Her work can be found at on her personal site here.

In her spare time, Katie enjoys being Mom to Sophie, hanging out with her four-legged child--Lily, running, cycling, and writing.

Robin started her career as an elementary school teacher in Maine, and then eventually moved home to Maryland with her husband, Frank. Robin then taught in the Howard County Public School System for several years and obtained her graduate certification in education with an emphasis on counseling. These work and learning experiences were wonderful!

After having children of her own, Robin chose to find employment primarily with nonprofit organizations where she had some work flexibility and gained valuable knowledge in business management, grant writing, and accounting/bookkeeping. Wanting more interaction with the people she served, Robin found her way to Christian Temple and now serves happily as the Church Administrator.
