School Reviews

The Knox School has provided my children with opportunities for leadership, to develop their talents and shine on stage, and to have a voice in the classroom in engaging in discussion with their teachers and peers. This caring community of faculty and administrators offers a student-driven experience with personalized course scheduling, a curriculum for college counseling, and the support and encouragement for students to develop new clubs and student organizations. Teen years are difficult and preparing for college is stressful. My children are not just surviving, they are thriving thanks to the support and opportunities that Knox has provided.

I highly recommend Knox to any parents looking for a school that not only has a stellar academic program but an amazing campus life. Knox really focuses on making your child the best version of themselves. I graduated from Knox in 2003 and my niece and nephew currently attend the school. This place is not just a school, but it is more like a family. I have seen the amazing difference Knox has made for the niece and nephew who are becoming mature, smart, and kind people. The faculty goes above and beyond for each student. Please come to campus and experience what Knox has to offer if you are looking for a private school for your child.

After issues with our district, we needed a place for our daughter and thankfully we found the Knox School. From our first visit, we knew this would be the perfect place. Warm and caring administration, knowledgeable and dedicated teachers combined with a beautiful campus and a nurturing environment make The Knox School a fantastic choice. Our daughter is already a new person after only 2 months - we cant wait to see what the next 2 1/2 years will bring.

The Knox School has been a perfect match for our son. The small size classes and personal attention the students receive from the teachers are exceptional. The coaches do an awesome job encouraging the kids and helping them to become the best athlete that they can be. All the administrators are present and know the kids by name. We can not say enough good things about this school.
