Hello! I’m Mark, one of the pastors at Hosanna, and I am glad to be with you! After serving churches in Detroit, MI and Medford, MN, I arrived with my family to the Mankato community in 2022 and truly love the experience of it all. My wife Joni and I have been married for 20 years and have been blessed with three kids: Kristen, Andrew, and Lauren. We are so humbled and grateful that God has called us as a family to be here!
My own calling is to share God’s Word in worship and disciple life ministry and to love and serve people with the relational joy that comes from Jesus. You’ll find me in flannel shirts most of the time, and you’ll also hear me share my long-time favorite verse in the Bible: “This is the day the Lord has made; let us rejoice and be glad in it!” (Psalm 118:24)

After serving as a pastor for 3 years in Michigan, I accepted the call to be a part of Hosanna’s pastoral team in 2024. From the start, my family and I realized how grateful we were to be connected to Hosanna’s amazing team and disciples!
My wife Claire and I have been married since 2016 and have 3 boys, Jaime, Elijah, and Seth, along with our Blue Heeler named Opie. I’m a native Michigander and an avid Detroit sports and Michigan fan (Go Blue!). I also enjoy cooking, running, reading, and talking long walks on the…sidewalk with my wife, kids, and dog.
One of my favorite Bible verses is John 3:17, “For God did not send His Son into the world to condemn the world, but to save the world through him.”

Care Pastor

Growing up initially as a corporate leader and corporate trainer for over 20 years I have always had a passion to make a positive difference is the lives of people. Realizing that the most positive impact comes in ones relationship to Jesus Christ, I attended St. Louis Seminary through the Specific Ministry Pastoral program graduating in February 2017. As an associate pastor now with Hosanna Lutheran Church, I serve the congregation as a part of their caregiving ministries as well as more recently walking with smaller congregations to help them navigate through a challenging and ever-changing culture. My highest priority has always been one of relationships stating that “People don’t care what you know until they know you care.”
I recently celebrated 36 years of marriage with my wife Rhonda and have been blessed with 4 boys, 2 daughters-in-law and now 2 grandchildren.

Pleased to meet you! My Name is Nate Sieveking and I’m the Missions Pastor here at Hosanna. I had previously spent 18 years in the business world before heeding God’s call to the ministry. It’s a joy an honor to serve this community, both in our Journeys ministry – our outreach to the greater Mankato area - and to serve on our Missions task force as we get to join in the mission of the church in spreading the Good News of Jesus Christ to the world.
My amazing wife Kathy and I were married in 2021 at Hosanna Highland and now live in the Mankato area. We enjoy traveling, cooking, movies, music and spending time with our dog Wonder. We look forward to get to know you. Feel free to call or email anytime!
