Castlio Elementary Testimonial 3

Castlio has been my home for 33 years. The children I have taught, the parents I have met, and the people I have worked for and with have been a true gift. Castlio is and always will be family to me.

Castlio Elementary Testimonial 2

Castlio is not just a school, it is a family. I was welcomed with open arms, encouraged and assisted at every turn. I was so happy with the school environment that I moved my own children to Castlio instead of their home school because I wanted them to belong to this family and share that experience with them.

Castlio Elementary Testimonial 1

Castlio is a special place to our family! The genuine kindness shown by the principals to students, staff and families alike is incredibly awesome to witness! Every teacher we've had in our 3 years here has been highly involved, gracious and intentional and very obviously teaching for all the right reasons. Kindness, grace and love runs rampant at Castlio. The relationships we've formed are truly a blessing and we feel so fortunate that our two kiddos attend this amazing school!
