We LOOOOOVE St. Mary's Academy!!! It is the most warm, inclusive, supportive, friendly community, while at the same time offering incomparable academic instruction and unparalleled leadership opportunities. Our daughter is happy every day! She loves her teachers, her friends, what she is learning, and how she is learning. SMA celebrates its students and their individuality, their power and their sensitivities. Students are encouraged to rise up in everything they do, without creating harmful and unnecessary stress and pressure. Our daughter and her friends have a saying, "only at SMA" to recognize the unique and. incredibly special experiences they have daily. SMA challenges its students to become change-makers in the world, and that they do. We cannot adequately describe the beautiful gift of St. Mary's Academy in our lives and in our daughter's life.

We have had a wonderful first year of high school at SMA. Our daughter has thrived in the highly-personal and student-focused learning environment that SMA provides. The faculty are incredibly talented and committed to helping each young woman be their best and explore their areas of interest, no matter how varied or specific they are. Ms. Ishwari's leadership has been an integral part of the strong culture of community and empowerment for these young women and families. SMA creates many opportunities to thrive in its core values of faith, justice, community, and respect. They have an extremely broad variety of clubs and student-run programs that students can readily engage in including Model UN, DECA, Robotics, Speech and Debate, Diversity, Outreach and so many more. They also have a wide variety of sports and other after-school programs students can explore as part of a team. We are very happy with the choice our daughter made to make SMA her high school home and highly recommend it as a place for young women to grow academically, socially, and personally!
