School Reviews

This is a very good school. The teachers and class size are great, and my kids are performing well above grade level. My kids were previously enrolled in a school in Arlington, but surprisingly this surpasses that school. I hope they keep it up.

I would highly recommend this school. It is a very tight-knit community where everyone is involved and looks out for each other. I am often amazed at what my daughter is being taught. The school offers a variety of activities to keep families engaged.
