Spirituality, the unique value of Catholic medical institutions, is not found in other hospitals. Therefore this hospital distinguishes itself from other hospitals in terms of providing spiritual value and the latest medical equipment to those who visit. In addition to that, there are convenient facilities and religious facilities for its patients and family members.
