St Irenaeus School All Years Reunion

Calling all SIS Comets! 


If you remember First Fridays, the May Crowning, beanies, colossal class sizes, venial sins, and a cast of mentors/characters such as Mrs. Peterson, Sister Mary Agnese, Sister Mary Cuthbert, Father Coogan, Mrs. Oakley (and too many others to mention) – and even if you don’t – mark your calendar for Saturday, October 19, 2019 for the St. Irenaeus School All Years Reunion. 

Whether you attended SIS for eight years or just one, come join your classmates at St. Irenaeus Parish Hall (what used to be our big box church) for hors d'oeuvres, drinks, 50s and 60s music and lots of fun memories.  This might be your last chance to clear – or embellish! – the Permanent Record that’s been following you around since you giggled during Communion practice in second grade.  Don't miss it!
