About Christ Alone Lutheran School (CALS)

Letter from the Principal

Parents take on an awesome responsibility when they welcome children into their lives. Christ Alone Lutheran School (CALS) in Thiensville, WI exists to partner with parents as they seek to nurture their children with God’s Word and a great education to help them develop their gifts and abilities to their fullest for the glory of God. Our K3 – Grade 8 school offers parents the opportunity to educate their children for 11 years. CALS not only offers outstanding curricula in all areas, but it also supports opportunities for students to explore their gifts in the areas of athletics and the arts (music, drama, art fair, forensics).

The most important thing we do everyday is to share the Gospel of Jesus with our students. By seeking God’s kingdom first, CALS helps parents with their most important responsibility: to bring their children to know and love Jesus. 

Please contact me if you are considering CALS for your child’s school. It will be an honor and a privilege to introduce you to our teachers, staff, and most of all, our students. CALS has much to offer to your child; don’t hesitate to call, email, or visit to find out how much.

Blessings to you and your family,

Principal Mike Henning

CALS Purpose

CALS promises to provide a Christ-centered, academically-sound education, supported by a caring and dedicated environment.

Our mission is “To know Christ and to make his love known in our homes, communities, nation, and world.”

Our vision is to continue to partner with families in providing an environment where our students can grow spiritually, intellectually, physically, socially, and emotionally. We do this by using God’s Word as the foundation of a well-developed curriculum, along with guidance from a dedicated, caring staff. We will all grow together in faith and love, and in service to the community, as we teach the Word of God in truth and purity throughout the curriculum each day.
