Founded in 1928 by the Sisters of Mercy, Our Lady of Mercy Academy offers young women an exemplary college preparatory education rooted in Christian values. Emphasis is placed on the development of healthy young women – academically, socially, emotionally, and spiritually. 

Our Lady of Mercy Academy offers a rigorous academic program with graduation requirements that exceed the minimum expectations of the NYS Education Department. Honors courses in English, Science, and Mathematics, 15 Advanced Placement Courses, and dual enrollment college courses are available. Additionally, the EDEN: EDucational & ENvironmental Research Program provides our students the opportunity to utilize OLMA’s unique 96-acre campus as a living research center. Housed in our newly renovated Mercy iCenter, our Computer Science Program offers courses in Computer Programming, Robotics, CAD, AP Computer Science and more. Beyond the required computer science courses, the iCenter allows for all faculty to utilize technology as an educational resource in the teaching and learning process. 

While our curriculum is rigorous and opportunities to excel abound, the most important quality of our school is the environment that ensures each girl is empowered, nurtured and challenged in a way that allows her to grow into the distinct person she is meant to become. Through Theology instruction, retreat programs, mission trips, and countless service endeavors, the Mercy woman serves to share her gifts with all. The Mercy Spirit is evidenced in the 50+ extracurricular activities offered, allowing students to tailor the high school experience to meet their unique needs and interests. 

Small class sizes and a dedicated faculty and staff foster a collaborative learning environment that will prepare students for college and beyond. The tradition of academic excellence is proven by the fact that the 114 graduates of the Class of 2018 earned $27 million dollars in scholarships.

Educating young women with Faith, Compassion, and Promise.
