5.0 Senior

12/12/2022

Thunder Mountain has small class sizes, a fun culture, and lots of opportunities to get involved. Perfect school for upcoming young adults.

I mainly did music while I attended Thunder Mountain, and I've got to say, they have one of the best music programs out there. Plus their academics and facility are just amazing. One thing I wish to see changed is the amount of bullying. There is a lot of bullying that goes on there that goes unnoticed. But overall, 9 out of 10 experience.

Very kind school, some teachers are iffy but it's an overall great time. People are treated fairly and, the dress code is very fair. Some teachers are jerks but you just have to get on their good side.

The only thing I have to complain about I that the way the school is built does not make it feel like a high school. The colored wings are juvenile and remind me of middle or elementary school. The spikes on the ceiling, metal, and concrete remind me of a jail. Never the less, the school is beautifu...

An excellent school and a friendly social environment. This school might be new, but there is no negative interactions within and it already has a great activity program.

I have to agree with the posted review. As a parent of a graduating senior I have found very little response to inquiries regarding my student from the teachers. I have encouraged communication by sending emails and have them go unanswered it could take 3 -4 emails to get response from the teacher....
