Welcome "Home" Alumni

Immaculate High School is home to more than 7,000 alumni!  Our alumni are an active part of our school community and we wouldn’t be Immaculate without YOU.  There are so many ways for you to STAY CONNECTED AND BECOME INVOLVED.  All alumni are invited to participate in our Alumni Committee as a class representative.  Plan a class reunion or if you’re looking to reconnect with classmates please visit our private and password protected Alumni Portal. Immaculate’s Blue and White Pages Business Directory provides the opportunity for members of our school community to support each other in business and professional endeavors.  Our Explore Program invites you to serve as a resource for our students by hosting a student for a job shadow day or providing an internship opportunity, speaking to a class about your field of expertise or participating in our annual Career Day.

Stay Connected


Your reunion year is an occasion to renew ties with classmates and reflect on what Immaculate means to you.  Reunion events can be formal or casual, at a restaurant, outdoor venue or banquet facility.  We look forward to working with alumni from classes ending in 4 & 9 to hold reunions in the spring and fall of 2024.
