About CWC

CWC Board

Central Wisconsin Christian is governed by a 12-member Board that is elected to three-year terms by the supporting constituency at the annual meeting in April.  Our Board members are parents and supporters of our mission of Christ-centered education.  The Board holds its meetings on the third Monday of each month.  Standing committees of the Board are the Executive, Education, Finance, Advancement, Transportation, and Athletic Committees, many of which include representatives of parents, staff, and Board working together to continually help CWC be a great school.

I am excited to see how positive changes can be made for the school when a need arises. Christian education is so important to our family because of how it builds on what is taught in our home.

Christian education is so important because children can see/learn from Christian teachers about how God and faith tie in to every subject they learn about. In a world where see increasing obstacles to faith/prayer in school, I treasure the Christian school for nurturing my child’s faith!”

I had the privilege of attending CWC and now enjoy that same privilege for our kids, and appreciate the hard work, dedication and commitment of the teachers and staff. As it says in Proverbs 22:6, ‘Train up a child in the way he should go, and when he is old he will not depart from it.’ It is our responsibility to help our children learn and grow mentally, emotionally, and spiritually. We feel Christian education is effective at all three of these goals.”

This is an exciting time for CWC, and I’m looking forward to the opportunity of serving on the Board and getting to know the Crusader family better. Christian education is so important because it teaches our children a biblical worldview of where God’s hand is at work in all things and that Jesus calls them to live for Him with all our heart, soul, mind, and strength. CWC is not only a place, but a community of believers where our children can grow and develop in their faith and knowledge.”

As temporary stewards of a world becoming more secular, Christian education helps us to reinforce the values that are taught at home and in church, as well as preparing our children for their roles as Christian citizens when they eventually leave our homes. I’m excited about being more involved in the present and future of CWC, learning more about how CWC operates and providing insight as needed.”

I love CWC, and I’m so glad we have the opportunity for our kids to attend here, especially the fact that Christ is central to EVERYTHING that happens at CWC.
