The completion of the Frassati Building was marked by a series of blessing rites conducted on December 10, 2021, presided over by UST Vice Rector Rev. Fr. Isaias D. Tiongco, O.P., along with Dominican Fathers. Following the external blessings, a Eucharistic Celebration was held, signifying the building's consecration and commitment to the University's mission.
The building is named after Pier Giorgio Frassati, an Italian activist who is considered as a saint in Roman Catholicism, for embodying "a legacy of social justice and service to the marginalized". Beatified by Pope John Paul II in 1990, Frassati serves as the patron of UST's Senior High School, reflecting the institution's commitment to "holistic education and moral formation". On 7 September 2025, he was canonized by Pope Leo XIV.
