St. Irenaeus Reopening Guidelines

St. Irenaeus Parish School submitted a waiver through the Diocese of Orange for in-person instruction. Our school is open for either in-person instruction or distance learning at this time. If Orange County continues the downward trend in COVID-19 cases, we will have all students on campus in the second trimester.
