Description
SJNMA offers a unique and safe environment. The faculty care about the cadets more than anything else. It's safe location physically located in the suburbs along with on campus security provide a great place. . .
I liked that we had structure. It taught me how to be on time and responsible. I also really liked that it was all guys. It made it easier to learn. Our teachers bent over. . .
The military traditions sets the school apart from other more traditional boarding school experiences. Very structured but always surrounded by other cadets in your company that doesn't make it feel like "all work and no. . .
