Mission Statement

Country Day School of the Holy Union, in the tradition of Catholic Education and the charism of the Holy Union Sisters, firmly believes that each person is created in the image and likeness of God, and thus the whole child is both celebrated and educated. A challenging curriculum strengthens students' academic skills and teaches them to think for themselves. Character is formed through age-appropriate responsibilities, and students are respected and taught to respect others, themselves, and creation. The school's community of wisdom and tradition of faith provide a supportive environment in which gifts and talents are recognized and nurtured.


Established in 1949, Country Day School of the Holy Union is a private, independent Catholic School serving students from pre-kindergarten through the eighth grade. Country Day School is under the sponsorship of the Holy Union Sisters. The order was founded in France in 1826 with a mission toward education. The school is situated on 16 acres of land located on Route 119 in Groton, Massachusetts.
