My younger child left Plattsburgh at the end of 2016, so not really that long ago. However, every student needs to feel comfortable with the environment of the school and you seem to have a lot of concerns about Plattsburgh so it’s probably not a good choice for you in any event.
Siena is very expensive and has a Catholic orientation. My friend’s D attended the school and, 5 years out, he’s not really sure that she got value from the costly education. She’s back in school pursuing a new course at a local SUNY.
