We are so happy with our decision to send our daughter to San Tan Montessori. We started her right at 18 months and she has just thrived. It is so much fun to watch her do things completely on her own and get so excited to see her friends. (more…)
We joined the San Tan family in 2013 with 1 kiddo in mainstream Kindergarten and 1 in Montessori Preschool. It was so great having both kids at the same school, whereas in most other situation, we would have been driving to two different schools. We immediately felt like part of the family and knew STCS was the right choice for us. (more…)

Love everything about this school. Students have their own individual learning plans. Couldn’t ask for a better school for my child.
Very nice teachers and staff!
I have had a great experience at san tan charter school, I have felt welcomed since day one and all the staff is very friendly and helpful. I can’t imagine a better situation for me to be in.
My granddaughter has excelled in this school. She loves to get up and be there.
My experience at San Tan Charter School has been no complaint. I have been to two different schools during my three years in high school. I am now a senior and I am enjoying every minute of it.
So grateful to have found this school where all three of our kids will be able to go for K-12. Love the various classroom options and the Love and Logic used throughout the school. Thank you!
This school has been a blessing for our family. Can’t wait to see what the future holds for this place. My daughter will graduate a Roadrunner!!!
Great administration, great teachers, fun sports and activities, the gifted program and the mainstream program are both AMAZING. Been here for years, so glad we found the school. They are great educators. Highly recommend.
Great school. Truly has the kids education as the highest priority
Without a doubt best school in Gilbert! Caring staff and teachers! They always teach outside the box!
Between all 4 of my kids attending San Tan, we have officially been in every grade between K-12th!!! I have loved it all, and am so proud of how San Tan has grown…it just keeps getting BETTER!
San Tan has made a huge impact on not only my life but my family’s and I would never change that for anything, because I probably wouldn’t have achieved half the stuff I’ve done now. It’s not only an honor but a blessing to be here at San.
