Our daughter is now a junior and on her way to a four-year college with excellent marks. The drama program has been very good for her outside of school and the AP program is giving her a good taste of what college will be like. School spirit is excellent and the parent community is very supportive of the school. Highly recommended.

Good school, I go there, I'm a freshman. But there is a vaping problem, I've seen people vaping in the bathrooms. So, that should be fixed for sure.
