Our Team
-
Errin Mulberry – Lead Pastor
I attended Cedarville University where I studied communications and Bible, and am pursuing my Masters in Ministry at Capital Seminary. I have been serving in full-time ministry since 2001, most recently as an associate pastor at a church in Philadelphia. I enjoy preaching, teaching, discipling, and counseling, and am excited to see how God will continue to use me for His glory. My wife, Jennifer, and I have 4 children. I love the Lord, my family, and the Philadelphia Eagles. I enjoy riding motorcycles, peanut M & M’s, and churros from Taco Johns.

Nate Moore - Connections Pastor
I attended Gardner-Webb University in Boiling Springs, NC and attained my Bachelors in Biblical Studies and Masters in Pastoral Care and Counseling. I have served as a youth pastor, student pastor, and as a lead contemporary pastor. In all of those things, my toil has brought me great joy—there is nothing greater than seeing people turn from death and run towards life in Jesus Christ! My wife, Carlene is a nurse and we have two dogs; we love hiking, road trips, and thrift shopping. I enjoy watching the Hawkeyes play, competing in any game, and joining in fellowship.

Kristi Schelhaas – Kids Ministry Director
I graduated from Dordt University with a bachelor's degree in art and I am currently pursing my master's degree in Children and Family Ministry through Bethel University. I have served as a volunteer in kids ministry at Calvary for 15 years and I am excited to be stepping into the role of Kids Ministry Director. I look forward to coming alongside kids and walking them closer to Jesus, helping them establish an identity in who God says they are, and cheering them on as they go into this world and do great things for Him. My husband, Sam, and I have 3 kids. I enjoy going to sports events (Go Bucks, Gazelles, and Jacks!), trying new candy, and summer.

Marisa Thompson - Preschool & Daycare Director
I attended the University of South Dakota where I studied Elementary Education. I received my Master’s Degree in Curriculum and Instruction from Mount Marty College. Before serving at Calvary, I taught Kindergarten for 8 years in the Yankton School District. Stepping into the role as the Preschool and Daycare Director will allow for me to continue my passion for education and children, but most importantly allow me to show each child how much they are loved by Jesus!
My husband, Adam, and I have 3 kids. We enjoy days at the beach, rock climbing, hiking, bike rides, and family game nights.

Josiah Croom – Worship Coordinator
I grew up in a small church near Fairmont, Minnesota. My family instilled in me a deep desire to continually be serving in church. Music has been a major part of my life as long as I can remember. God eventually took me to Rockford, Illinois where I attended City First Leadership College to develop my skills in the worship world. I have a passion for setting an environment for people to encounter Jesus, and am so excited to do that here! I love quiet spaces, coffee, and a good burger.

Amy Horning - Office Manager
I grew up in northern Minnesota, then attended University of Northwestern in St. Paul, MN where I studied Math Education. It was there I met my husband Erik, who grew up in Freeman, SD. After many years in the Twin Cities, a job change for Erik led us to Yankton and Calvary. Erik and I have 3 children, and our family life revolves around our kids’ school activities and golf. I began my career as a teacher, left that to be a stay-at-home mom, went back to teaching, and then God placed this job of Church Office Manager before me. Each of these roles has kept me on my toes and taught me to be ready for anything! I love strong, black coffee, a good book, and MN sports teams.

Krista Vogt - Bookkeeper
My name is Krista Vogt and I am the Bookkeeper. I have been working for Calvary since August 2022. My husband Ty and I have been married for 17 years. Ty is a Senior Controller with the Army Corps of Engineers. We have 5 kids: 4 girls and 1 boy ranging from soon to be preschool to college. Our oldest daughter, Ashlyn, is in pre-med and works as a CNA at Sanford in Sioux Falls in the surgical trauma/cardio and ICU units. Brooklyn works here at Calvary in the daycare. Jaelyn and Eislyn keep very busy with gymnastics. Our son, Kasen, stays busy taking things apart, playing outside, building with Legos, and will be starting preschool and soccer in the fall. In our rare spare time we try to camp, kayak, and if Ty had his way…golf every day. Calvary has been such an amazing blessing to our family, from Sunday Service to Awana, Rev56, Pursuit, and so much more. We are all very happy to be a part of the Calvary family and it is just an added bonus that I get to work here, too!

Erin Schuster - Ministry Coordinator
I grew up at Calvary and love serving as ministry coordinator; it is truly a JOY and a privilege to come alongside staff and volunteers as we work together to further the Kingdom! I graduated with a degree in elementary education and have served in various kids’ ministry roles at Calvary. My husband and I enjoy spending time with our adult children and their families, spoiling our furbabies, and playing games. I’m also the crazy bird lady who is constantly taking bird pictures and is happy to have birding conversations with anyone willing to listen (God tells us to “look at the birds of the air,” right?)

Krista De Wit - Office Assistant
I attended Cosmetology school in 2005 and worked as a hairstylist for 10 years. However, for the last 7 years I have been a stay-at-home mom. I started at the church office in the fall of 2022. I like helping whoever stops by or calls the office. There is always something new going on! Serving the church family of calvary has been such a blessing. I moved to Yankton in 2019 with my husband Matt and 4 kids. We keep busy with the kid’s activities & are loving this busy stage of life! We enjoy bike riding, boating, campfires and tetherball.
