School Reviews

Although I did not appreciate the boarding school ambiance, Mt Hermon gave me an A+ education. As a retired college professor, I can now say it taught me the key elements of great teaching. It helped me become in the 1970s one of the best college teachers in the state of Texas. Now, recently; ly retire,d I can now look back, and say "Thank you, Mt. Hermon." In addition, as the son of parents living abroad, Mt. Hermon also took care of me during the holidays. Not many other schools did that.
