San Tan Charter School’s new campus opens July 2026

San Tan Charter School has broken ground on its new Queen Creek campus slated to open in July 2026.

The school is at 18979 S. Signal Butte Road, near the intersection of Signal Butte and Germann roads.

Attending the event were representatives from the Queen Creek Chamber of Commerce, Queen Creek Town Council Members Bryan McClure and Dawn Oliphant, local business owners, owner of San Tan Charter School Chris Sippel, along with the building team and principal of the new school, Katie Cox.

"As the future principal of this new campus, I couldn't be more proud to be a part of this next chapter in San Tan's story,” Cox stated in a press release. “Almost 20 years ago, a husband and wife, both educators, found themselves unable to locate the kind of school they envisioned for their own children. Determined to create something better, Chris and Rita Sippel took a risk and ventured into the unknown and founded San Tan Montessori. What began as 40 students has now grown to into a thriving community of over 1,000 learners."

The Signal Butte campus will offer a Montessori Preschool. Programs include Love and Logic’s nine essential skills, a Montessori peace table for conflict resolution, and the Music Together program to encourage movement and self-expression.

"On behalf of Mayor Julia Wheatley and the town council, we want to welcome you to the Queen Creek family,” Oliphant stated in the release. “As parents, we love that we have choices in Queen Creek; we have district schools, private and charter schools, and that's what makes us a great community."
