At St. Mary’s, we nurture the intellectual, physical, emotional and social development of each student. Our challenging array of core curricular and extra-curricular programs is designed to enable each student to achieve excellence and success. We provide a positive and safe learning environment, where a spirit of cooperation, friendship and mutual respect helps to maximize individual achievement.
