Our mission at St. Mary’s is simple: “World-Sized Hearts. World-Class Minds.” By equally engaging the heart and the mind, we inspire and empower our students to change the world with purpose and understanding. Our students are inquirers. By asking “what” and “why,” they begin to understand their role in the “how.”

St. Mary's Programs
Understanding who you are and having the self-confidence to adhere to those decisions isn’t something we take for granted at St. Mary’s School. We offer many programs to empower our students and nurture their interests.
Early Education Early Preschool-Early Kindergarten
The principles of St. Mary’s School – Early Education Program follow the International Baccalaureate (IB) standards as well as the guidelines for developmentally appropriate practice set forth by the National Association for the Education of Young Children (NAEYC).
Lower School Grades Kindergarten-5
The Lower School curriculum focuses on the development of the whole child as an inquirer, both in the classroom and in the world outside. We teach our students to ask "what" and "why" in a way that demonstrates that they are an essential part of the answer to "how."
Middle School Grades 6-8
Middle School students pursue a rigorous academic program in a positive, supportive environment. Through the IB Middle Years Programme (MYP), students are taught how to be inquirers capable of accessing and analyzing information. They learn by doing; connecting their studies in the classroom to the real world. Thinking critically, creatively and taking a disciplined approach to their studies, students gain confidence in their ability to manage their own learning. Recognizing they are part of something larger than their local communities, St. Mary’s Middle School students develop an understanding of global challenges and a commitment to act as responsible citizens.

"Winning the IB Scholar award makes me feel so good. It lets me know that my hard work and dedication is not going unnoticed. But I think it's more than just an award, it represents commitment to growth and the courage to be vulnerable. It really shows me who I am through all the IB Learner profile attributes, like a risk taker and communicator."
