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. Through a challenging and supportive environment encompassing academics, arts, athletics, community service and many other co-curricular activities, each young woman is provided the opportunity to discover her strengths and talents and to become an independent, creative thinker who acts with social responsibility and justice. Upon graduation, Mercy alumnae are empowered to lead, serve, and succeed in their colleges, careers, communities, and lives.

Our Lady of Mercy Academy offers a rigorous and well-rounded academic program. Honors courses in English, Science, and Mathematics, 14 Advanced Placement Courses and college course offerings through St. John’s University 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. The brand new Mercy iCenter is home to our expanded computer science program. 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.

Our highly accomplished and dedicated teaching staff is committed to preparing students to reach their full academic potential. Small class sizes 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 131 graduates of the Class of 2016 earned $27.3 million dollars in scholarships with 100% of students continuing their education in college.

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. At Our Lady of Mercy Academy, each student is nurtured to grow into the woman God has intended her to be.
