Catholic Values

Community & Belonging

A small, welcoming Catholic school in the heart of Chestnut Hill blending strong academics with a deep commitment to character, community, and care in a warm, family‑centered environment. For over 160 years, OMC has prepared students to live as kind, thoughtful, and capable contributors in today’s world.

What Defines an OMC Education

An OMC education is shaped by more than academics alone. It’s defined by meaningful relationships, exceptional teachers, engaged families, and experiences that help students grow in character, confidence, and curiosity while preparing them for success in high school and beyond.

Character Through Action

Catholic values are woven into everyday life at OMC through service, leadership, and care for others. Students don’t simply learn about compassion, generosity, and responsibility, they practice these values through classroom experiences, school traditions, and meaningful opportunities to serve both their local community and one another.

    A Richly Diverse Community

    OMC brings together families from a wide range of socioeconomic, ethnic, racial, and faith backgrounds. These diverse perspectives enrich classroom conversations, strengthen friendships, and prepare students to learn with empathy, respect, and an appreciation for the experiences of others.

      Small School. Big Opportunities.

      With one class per grade, every student is known as an individual and supported by teachers who understand their strengths. Our location in the heart of Chestnut Hill complements that personal attention with educational, cultural, and community experiences that broaden students’ perspectives beyond the classroom.

        Family Engagement & Volunteerism

        The strength of OMC lies in its community of dedicated families, faculty, and staff. Volunteering at school, coaching athletics, welcoming new families, and supporting one another beyond the school day create a culture where every child is surrounded by caring adults who lead by example. It’s this shared commitment that makes OMC such a special place to learn, grow, and belong.

          A Lasting Tradition

          For more than 160 years, thousands of families have chosen OMC for an education rooted in academic excellence, character, and community. We remain committed to helping every child reach their fullest potential while fostering the relationships, values, and sense of belonging that define the OMC experience.
