Our Mount Sinai High School military alumni are some of the most outstanding people we know and this page recognizes them and everything they have done! Not everyone gets to come home for the holidays and we want our Mount Sinai High School Military to know that they are loved and appreciated. All of us in Mount Sinai are proud of our military alumni and want to thank them for risking their lives to protect our country!
