The first alumni of St. Irenaeus Parish School are the members of the Class of 1968. They started at St. Irenaeus as 4th graders when the school first opened in September of 1963. Each June as a new class of 8th graders graduates we welcome them as our newest school alumni. We currently have over 2500 alumni and are proud of the fact that over the years many have returned to their alma mater as members of the faculty and staff. We are also proud that many alumni recognize the value of the faith-filled educational foundation that they received and have chosen to enroll their children at St. I.
