Our Team


Mark Johnston {Fifth & Sixth Grade Coordinator}

In 1989, while working in the Sports Medicine field, the Lord called me to student ministry.  I started out as a volunteer for two years and that eventually led to me becoming a full time Youth Minister in the Presbyterian Church in America where I served from 1992-2002.  In 2003 I arrived at Church of the Apostles with my family and immediately volunteered in the STS ministry where I served for five years.  I was asked to come on staff in 2008 to serve the families in STS.  My desire is to minister to our families and see them grow in their relationship with Jesus and be equipped for their ministry wherever God has called them to serve.  I have been blessed with an incredible wife Monica and three children Caroline, Elijah and Gideon.

Kristin Waites {High School Assistant Coordinator}

I grew up in Marietta and graduated from Valdosta State University in May 2011. The Lord has blessed me with the opportunity to work with and serve the High School students here at The Church of The Apostles. Throughout college, God revealed to me that He was calling me to a life of ministry. I am excited to be involved in youth ministry and to have the privilege of seeing the students grow into a deeper and more intimate relationship with their Savior. God has given me a passion for pouring into young women and teaching them how to grow in their relationships with Christ. I want to make myself available to each student and their families as we embark on our spiritual journeys together. God has called each of us to share the gospel and His love to those we encounter, and it is my joy to be a part of that as a STS staff member.

Anna Witt {Assistant Coordinator for Fifth – Eighth Grades}

I’ve had the privilege of working with Elementary and Middle School students for the past 8 years. Some of my favorite experiences include being a part of the worship team in Kid’s Connection and STS here at The Church of The Apostles as well as assisting with FCA in Cobb County.  After graduating from KSU in 2009, the Lord graciously opened a door for me to join our Youth Ministry Team.

My husband and I live in Atlanta and are excited to be a part of what God is doing in our city. It is such a joy to see students passionate about their Savior. We have some awesome students in STS and look forward to seeing all God will continue to do in and through their lives!

Jenny Sessoms {STS Administrative Assistant}

I grew up as a child of missionaries in Mali, a nation in Western Africa. I’ve always had a love for ministry but God confirmed this passion in me late in high school and all through college. I moved to Atlanta in 2009 after I finished college and God opened the door for me to work here in STS in 2010! It is an honor to be a part of such a God-centered ministry and church here in Atlanta. I love working with our students and families; there is little that is more rewarding than seeing God work in the heart of a teenager.

Favorite Bible Verse: Romans 1:16-17 – Never be ashamed of the Gospel!!!
