School Reviews
5 10/10/2025
The teachers are great at this school, but the principal and superintendants are not. They do not listen to you or handle any problems. They shine you on and don't deal with them.
The staff and teachers are not like that. I do wish there were more art programs but we did get music this year which is great.
If you are a hands on parent and have your own opinions this would not be welcomed by the principal or district superintendant.
