Centennial Planning Portal

Welcome to Mercy's Centennial Planning Portal!

A centennial is a once-in-a-lifetime milestone, and we hope you'll be part of the celebration.
 
Throughout the 2028-2029 school year, the Mercy community will come together for a year of special events and opportunities to celebrate 100 years of Mercy---and look ahead to our next century.

Here, you can explore ways to get involved, from helping plan Centennial events and sharing your favorite Mercy stories and photos to hosting a regional gathering or making a gift that supports the next 100 years of Mercy.
 
However you choose to participate, you will help honor our shared history while strengthening our mission for generations to come.

Check back often as Centennial plans, events, and new ways to participate are announced!

A History of Mercy

Our Lady of Mercy School for Young Women is rich with history and tradition. Since the school opened in 1928 we have grown from 75 freshmen and five teachers, to 800 students and more than 100 faculty and staff. We’ve expanded several times, adding a middle school, new gymnasiums, an auditorium, and dozens of athletic teams. More than 14,000 young women have graduated from Mercy… and we are just getting started!
