Principia School Reviews
Our interaction with the teachers and staff members has been very positive because the school promotes an environment that regularly brings parents, teachers, and faculty together to celebrate our kids educational and spiritual development. Our daughter is a beautiful, smart, and engaging little girl that have made friends in and out of school. Although it is her first year, she has had numerous playdates and met wonderful and caring families. For us this is one of the best features of Principia! We love Principia’s emphasis on strong character education and academic excellence!
It is an ambitious goal to demonstrate love in all things and from the moment you come on campus you can feel that you are in a place where love is guiding and leading.
The academics are top notch and the teachers and administration are always keeping the educational styles and activities forward and future thinking.
The amount of ‘in the field’ learning and adventure opportunities are incredible.
The sports have amazing coaches and profesional level facilities.
There is no way to explain how amazing the school is, so I suggest if you are at all interested please schedule a tour!
The school has been an incredible blessing for my family. The character growth, the sense of community, the cutting edge academics and athletics…
I can not recommend the school enough.
