Please bear in mind that at this time Poughkeepsie Day School is PreK-8. The site has shown erroneously that it operates a high school. It does not do so in 2026.

We couldn’t be happier here! It’s such a warm welcome every morning greeted by Mrs. Glynn and the father. They know every single kid! It’s a great environment!

Having toured every Catholic school in the area --and possessing insider knowledge of many-- I can state with confidence that St. Mary's is easily the best Catholic School in the Hudson Valley. Our family can only recommend the school most highly, as it is Catholic Classical education at its finest. The administration is masterful and kind and the teachers are equally masterful, full of experience, and teach the *whole child* as an individual. In terms of early elementary instruction, the instruction is interdisciplinary and creative in the most beautiful way. Social studies lessons on folk tales offer tie-ins to mathematics, religion, and English, as well as problem solving, and science is very much taught in a "hands on" experiment-based manner. We love everything about this school and certainly the wholesome, value- and faith based education our children are receiving!
