Last evening, we had the pleasure of honoring Mrs. Rachele Pla for being selected as a recipient of the Archdiocese of Washington’s Golden Apple Award. Mrs. Pla was chosen for this prestigious honor in recognition of her outstanding contributions to our Catholic school community, the Church, and society as a whole.

Mrs. Pla is an exceptional educator who exemplifies a daily commitment to living out the Catholic faith. Through her dedication, compassion, and leadership, she inspires both students and colleagues alike to see the face of Jesus reflected in one another and to strive to do the same in their own lives.

CONGRATULATIONS, MRS. PLA!

Today, following Mass, our school community joyfully celebrated the May Crowning of the Blessed Mother, for whom St. Mary of the Assumption School is named. 🌸👑

It was a beautiful and prayerful celebration, made especially meaningful for our second graders, who recently received the Sacrament of First Holy Communion, and our eighth graders, who recently celebrated the Sacrament of Confirmation.

We are grateful for this special day and for the many blessings bestowed upon our school community.

Thank you, Jesus Christ, for all of our many blessings. 🙏🏽

Our 2nd grade celebrated their First Holy Communion today!
