History & Leadership
They shall proclaim His righteousness unto a people yet unborn – for He has done it!”
-Psalm 22:31
A History of God’s Faithfulness
Nearly 125 years ago, a small group of immigrants from the Netherlands started Sheboygan Christian elementary school. They had a vision for Christian education and trusted in the words of Psalm 22:31- that future generations- yet unborn!- would serve the Lord through this school for years into the future.
Through the founding of Sheboygan County Christian High School in the late ’60’s, the merging of the two sister schools in 2015, and a brand new state of the art unified P-12 campus in 2021, the future for SCS has never been brighter. Today, our school community is much bigger and much more diverse than our founding- but we are all spiritual descendants that our founders prayed for! We are honored that God is using us in this generation to continue the same world-changing mission that we’ve had since our founding.

They attend and are actively involved at Calvin CRC in Sheboygan. As an alumni, Bryce can’t be more excited to be at SCS and be a part of helping to shape, guide, and instruct students in living out the mission of SCS.

John WarmusGraduate 2004
Director of Advancement & Finance, Van Driver
Education: Bachelor of Science in Political Science and Government, UW – Milwaukee
MBA in Project Management, Lakeland University
John has spent more years roaming the halls of Sheboygan Christian School than any student should…. he started at SCS as a 4K-er and graduated (not top of his class) in 2004. He loved growing up within the Sheboygan Christian School community. He has fond memories of walking to school with his siblings and neighborhood classmates. After SCS, he attended UW-Milwaukee and graduated with the world’s longest (and least useful) degree title; ask him to rattle it off next time you see him!
His greatest “win” in life was marrying Betsy. They recently celebrated our tenth anniversary. Betsy and John have three daughters whose personalities are as different as their hair colors. Natalie (5), Grace (3), and Sophie (1) provide an endless supply of entertainment and busyness. His favorite hobby is spending quality time with his family and friends. His family attends Hope Reformed Church. Another ‘hobby’ and major source of joy for him has been his service to and the community around Camp Calvin. Camp has been a part of his life for 24 years.
He feels blessed to be in his role at Sheboygan Christian School.
