About
Our History
A Passion for Teaching
All Sisters of Mercy trace their roots to their founder, Mother Catherine McAuley of Dublin, Ireland. In September 1827, she opened the first House of Mercy, as a place to shelter and educate women and girls. In 1831, Catherine founded the Sisters of Mercy.
Their passion for teaching is what brought the Sisters of Mercy to Omaha in 1864. They have been part of Omaha’s educational community ever since. The Sisters opened the first Catholic school in the area at Mount St. Mary Seminary, located at 24th and St. Mary’s.
That legacy of academic excellence and a faith-based education continues with our current faculty and staff who are committed to the values of Catherine.
At the Heart of Historic Morton Meadows
After years of planning and careful design, Mercy High School officially opened its doors at 48th & Woolworth on November 2, 1955. Nearly 675 students attended classes that year: over 150 students from St. John's, over 300 from St. Mary's, and over 200 in Mercy’s first freshmen class.
Some things have changed through the years. The school has undergone renovations. Some things have remained the same. Historic Morton Meadows has always been our home. From here, we have welcomed young women from every area zip code for more than 60 years.
