Welcome from the Principal

Mission Grammar School Principal,
Caroline Sliney

Welcome to Mission Grammar School!

Thank you for choosing Our Lady of Perpetual Help, Mission Grammar School. As the oldest Catholic elementary school in the city of Boston, we’ve proudly served scholars and families since 1889. For over 135 years, we have lived our commitment to Unity in Diversity and Excellence in Education, rooted in faith and the values of the Gospel.

At Mission Grammar, we believe in the brilliance of every child. Each scholar arrives with God-given gifts, and it is our privilege to help them see and grow that brilliance every day. Guided by our CARES values—Community, Achievement, Respect, Equity & Inclusion, and Safety—we provide a high-quality education that is rigorous, standards-based, developmentally appropriate, and culturally relevant. Every scholar is capable of learning and achieving at high levels, and it is our job to ensure they have the academic, social, and emotional support to do so.

We believe deeply in a Culture of Achievement in every classroom, every day. Our curriculum reflects the diversity of our scholars, enriched with books and resources that represent many races, cultures, and lived experiences. We want our scholars to be proud of who they are and the work they do, building the confidence and skills to be change makers in the world.

We believe in partnership with families, our scholars’ first teachers. Together, we create a learning environment where every child is known, loved, and supported. We extend learning beyond our campus into the city of Boston, providing field trips, community partnerships, and real-world experiences through collaborations with local hospitals, colleges, and organizations.

We believe in family, Mission Grammar is more than a school; it is a community. Our scholars, families, and staff form a strong, loving network where everyone’s contributions matter. We are blessed with dedicated teachers, engaged families, and brilliant scholars who inspire us to grow and improve every day.

When you join Mission Grammar, you enter a high-quality, faith-based learning community committed to celebrating the gifts of your child and preparing them for a bright future—from the very first day of school to the road to college and beyond.

Welcome to Mission Grammar. I look forward to partnering with you and your family as we continue this proud tradition of faith, excellence, and unity.

All the best,

Caroline Sliney
Principal
