A century ago, the Sisters of St. Joseph of Carondelet dared to dream of a place where education would ignite purpose and power change. From a rugged hilltop, they built Mount Saint Mary’s, which has become a beacon of academic excellence.

For 100 years, the Mount has empowered leaders and transformed lives. Today, we honor that legacy and look ahead with bold determination to the next 100 unstoppable years.

100 years. One legacy.
