This is my first year at Rivers and I really have loved the school. The workload is definitely a lot but the teachers go out of the way to make sure you understand. Rivers also has a very strong community and great sports teams and an awesome music program.

I have a daughter who graduated from Rivers and a son who just started and I can't say enough about the quality of the faculty, the diversity of the school's programs and the excellent sense of community. My kids are very different (the oldest is more into the arts, music, and clubs and the other into sports) and Rivers has been a great fit for each of them. The academics are very challenging but at the same time the teachers make the kids want to learn and push themselves. Great school!

We have been very impressed by the teachers at the school. They are substantive and encourage rigor, but they're also extremely available and helpful and want the students to do their best. The school has a number of great electives and interdisciplinary programs and very thoughtful pedagogy. The school is also making real efforts in the realms of diversity and inclusion.
