School Reviews
5 10/10/2025
As a freshmen at Montgomery Blair, I notice that most of the programs there are phenominal. The music and other extra curricular activities are amazing. They take trips to New York and they actualy take trips unlike my past schools. Blair has won between 25 and 50 athletic awards from lacross to football. I am unsure about the level of parent involvement but of you send your children to Blair just be sure to let the know that the teachers don't play around.
