Cornerstone Christian School is a ministry of Cornerstone Evangelical Presbyterian Church and is located half way between Detroit and Lansing in southeast Michigan.  In 1999, an individual donated a significant amount of money to start a private Christian school as there were not many in our area at the time.  Other Christian schools were visited in order to develop a vision of what they wanted CCS to be.  We opened our doors offering K–3rd grade.  As student population warranted, we added 4th - 8th grades.  We completed our grade list in 2009 with the addition of our preschool.

When we opened our doors in 1999, our principal, Nancy Brownsey, and a steering committee provided for us our foundational documents. These documents provided a focus for our entire constituency for the first few years of our existence. In 2006, our staff embarked on STAR “Steps Toward Achieving Recognition” through the Association of Christian Schools International. As part of our project, the entire staff re-examined our mission, vision, philosophy, and educational beliefs. These updated documents are included in the school Handbook.

In June, 2009, after 10 years of faithful service, Nancy Brownsey retired.  Dr. Arthur J. Hunt & Mrs. Sandra Nettleingham led the school as Head of School and Principal. Presently, Dr. Vicki Kloosterhouse, Head of School, leads the school along with Mrs. Michelle Annas, Principal.

CCS's hallways and many classrooms received a facelift in 2023 as part of the our church's SHINE project.
