Wes parent here. There is minimal Greek life (there are three “fraternities,” only one of which has Greek letters, and they are all co-ed) but lots of clubs/groups that spawn social life. It’s not a “rager” kind of place; it’s more of a house party/hang out place. Athletes aren’t in any way dominant, and while there is certainly some social separation, there’s also plenty of overlap (my very very non-athlete kid is dating an athlete, for example).
There’s a really wide range of kids there, and it’s very welcoming. I agree with the overall descriptions from Niche, with the caveat that I think “weird” is good. Students are smart and curious, often with double majors that show a wide range of intellectual interests. The student body is largely left/progressive, but there are plenty of students with other perspectives, and there’s lots of heterogeneity even within the left/progressive space. The president (who is not from the left) is very big on freedom of expression, exchange of ideas, etc.; he’s been very outspoken amid the current administration’s university crackdown.
I think a visit will help; it has a distinct vibe that appeals to some and not to others.
