My experience in the building has been great. I haven't had any issues at all. My favorite part is the technology classes they offer especially AP computer science. The worst part is in my opinion the food options. The only changes I would like to see is better heating around the building.

Old Mill High School is a great school. It has a lot of different programs and student diversity. Most of the teachers do a great job of teaching students what subject they want and it's a lot of classes to pick from.

Disgusting faculty to work with, lack of social-emotional intelligence all-around. Admins lack the ability to administrate their way out of a wet paper bag
