School Reviews
5 8/2/2019
This is a wonderful school. Education is top notch. Discipline is fair and enforced which I love. They could use some major work to the high school building for safety but other than that, absolutely no complaints. If you can afford it, it is worth the money. All teachers are required to stay up to date on certifications.
