Today, our school community gathered for the beautiful tradition of May Crowning, honoring our Blessed Mother, Mary. With flowers, prayer, and song, our students paid tribute to Mary’s grace and guidance, a cherished tradition that has been celebrated by generations before us and continues to inspire hearts today. May she continue to watch over our school and lead us closer to her Son, Jesus. #MayCrowning #CatholicTradition #FaithInAction #MaryOurMother
