About Us

President’s Welcome

Welcome!

Many thanks for taking time to explore Mercy High School, an outstanding Catholic college preparatory school for 445 girls in grades 9-12 sponsored by the Sisters of Mercy. Founded in 1960, Mercy carries forward the rich legacy of Mercy education in Baltimore, which began in 1867. With a dual commitment to excellence and innovation, Mercy was the first and only Catholic girls’ school in the Archdiocese of Baltimore to gain authorization as an International Baccalaureate World School—a prestigious designation recognized by colleges and universities as the “gold standard” in education.  

Shaped by the vision and values of the Sisters of Mercy and their founder, Catherine McAuley, Mercy High School is part of a global network of 195 Mercy secondary schools. We share in a sacred mission to help our students live out our Mercy values—excellence, hospitality, service, justice, and compassion—so our Mercy Girls can become the Women of Mercy God calls them to be.

Drawing from more than two centuries of experience teaching girls and women, the Sisters of Mercy are experts in the education of adolescent girls. A Mercy commitment to healthcare, expressed in Baltimore through our sister ministry, Mercy Medical Center, also informs our thoughtful, personalized approach to guiding our Mercy Girls through the joys and challenges of their formative high school years. Indeed, an exclusive focus on the high school experience distinguishes Mercy. With every Mercy Girl joining our community as a ninth grader, the freshman year is “a level playing field.” Every new Mercy Girl starts in the same place, building new friendships and exploring new interests. In partnership with parents, our exceptional teachers draw out the very best from our Mercy Girls.  

Our results are impressive. The Class of 2024’s 102 members earned a staggering $23.1 million in merit scholarships—an average of $226,500 per graduate—to colleges and universities across the country. And, more than ever, families are eager to learn more about what a Mercy education can do for their daughters.  

With strong interest in Mercy and limited places, I urge you not to delay in beginning your Mercy journey. Please join us for our admissions events, and our myriad of theater, dance, and musical productions, athletic contests, alumnae gatherings, and so much more! We look forward to offering you our warm Mercy hospitality, firmly rooted in the timeless charism of the Sisters of Mercy. 

Sincerely, 
 
Mary Beth Lennon ’85
