San Tan Charter School began as a small private Montessori Preschool and Kindergarten in 2006, and quickly filled to enrollment capacity. Parents, wanting more for their children’s education had expressed concerns about the local quality of Elementary Education programs, and the price of local private school education. Parents raised concerns that their children would fail to thrive in the overcrowded local public schools as they transitioned to first grade.

The owners of San Tan Montessori, Dr. Kristofer and Rita Sippel, heard their concerns, and saw the need and demand for a new type of free public school in Gilbert. San Tan Charter School developed a K-6 Inquiry Based Learning Curriculum model incorporating applicable Montessori concepts and materials for a Public Charter School program. The charter for San Tan Charter School was approved by the Arizona Board for Charter Schools in January 2008 after a rigorous process, and started with less than 100 students.

Since then, the school has grown to include a middle and high school, with over 900 students in grades PreK-12 for the 2017-18 school year. Our Teaching staff includes award nominees as well as winners for some of the highest awards in the State. San Tan offers programs such as daily PE, music, art, and library in addition to our State Championship Athletic Teams, our programs are thriving.

San Tan is happy to announce that in December our board of directors has made the decision to invest in a $19M dollar expansion to our popular High School experience to include a state of the art elective building housing a full home economics classroom, video arts lab, and music studios. In addition, we will be adding football, softball, and baseball stadiums, a 30,000 square foot gym with three full size basketball/volleyball courts. The new campus will be located at Power and Elliot Roads and will open August of 2018.
