School Reviews

5 11/3/2022

I absolutely LOVED my time at the mountain. I would not change one thing. I felt that the administration genuinely cared for the students in a way that was different than the typical school. Classmates wanted to see each other succeed. This isnt to say there wasnt the typical high school drama. But truly, KMHS is the reason I am where I am today.
