Carl Vonderhaar

kids pastor

"God doesn’t use perfect pictures; He uses broken people." - Pastor Carl

Email Pastor Carl

As a 25-year resident of Citrus County, Carl has learned to love life in a small town. He and his wife, Megan, have been ministering to youth and families for the past 16 years. Making an eternal impact has been their driving passion. That passion led them to Lakeland, Florida where Carl obtained a Bachelor’s Degree in Business, from Southeastern University. After graduating, Carl, and his family spent three years on the mission field serving the needs of vulnerable and orphaned children on the continent of Africa. His time, both on the mission field and here at home, has taught Carl that life should not be lived alone. There is joy and power in community. As our Children's Pastor, Carl's greatest joy is to see families grow closer to God and to each other. He was licensed as an Assemblies of God minister in July of 2017.

Mackenzie Ball


Email Pastor Mackenzie

Mackenzie has been running the halls of Calvary Church since she was almost two years old and has always felt the call of God on her life to be a worship leader.

During her time there, she was equipped in their worship department and got to travel and minister across the country with Chosen and also Corey Ball Ministries. While in Alabama, she met and married Corey Ball. In December of 2020, they welcomed their first-born daughter Harvest Ball. Now more than ever, Mackenzie is deeply passionate about worship and leading God’s people into His presence.

Nothing is more important to her than creating an environment where the Holy Spirit is able to move.
