Marymount students, faculty, staff, administrators, trustees, alumnae, and parents are welcome to gather to mark special occasions throughout the year at all-school Masses. These occur in September at the Mass of the Holy Spirit, on February 2 to celebrate Founders’ Day, and on the following Holy Days: Feast of All Saints, Feast of Immaculate Conception, Ash Wednesday, and the Feast of the Ascension. Students from all divisions serve in leadership roles during Mass as lectors, singers, altar servers, and in the entrance and offertory procession. Every student, regardless of her faith tradition, is welcome to participate in any way she feels comfortable. “Big sisters” from the Classes VII through XII accompany their “little sisters” in Classes I through VI to each Mass.
