Sanford is a rare find in school experiences. The school culture fosters a level of respect and integrity that makes it an easy place to focus on learning and development. It is also an environment where the students can truly explore areas of education and extra curriculum activities that fuel their individual passions. Class sizes are small so there is plenty of engagement where teachers truly get to know the students.

I can’t be the only person confused about diversity at Sanford. This can’t be going unnoticed. They talk about diversity a lot and make an effort to incorporate it into most aspects at school but it seems like it’s not the reality. Head of school, head of upper school, head of middle school, entire...
