School Reviews

When I attended, St. Mark's employed the best English teachers anywhere. We learned the art of writing. Ben Bradlee, who edited the Washington Post for decades, attended St. Mark's. All their lives, students remember the athletic program. When one attends school with someone, one remembers those classmates as long as one lives.

St. Mark's does many things well: The school fosters and encourages an environment where diversity is embraced, students have voice and recognition, and relationships are strong. The generally positive atmosphere represents the student body, which is full of many different types of people. The many opportunities to pursue academic interests both inside and outside the school makes SM a great prep school. Lastly, the athletic teams value perseverance and hard work over winning, and the coaches are very skilled.
Endorse St. Mark's School. Endorsements should be a few sentences in length. Please include any comments on:
- Quality of academic programs, teachers, and facilities
- Availability of music, art, sports and other extracurricular activities
- Academic or athletic awards
