Tufts sounds like it could be a great fit for what he’s looking for. (Butvyes, there is a language requirement.) While any of the more rural LACS will likely offer what he wants, they don’t sound like the vibe he’s looking for (with Vassar as the possible exception).
He has the stats for all these schools, btw, so it’s more a matter of him conveying who he is as a person and that he’s a fit for the school.
