Hi @LupineChild, sorry to hijack his thread, but I’m a CMU upperclassman as well and I think my experience with housing would be helpful for you. For my freshman year, I was in the dormitory called Henderson house. It was a pretty small dorm, in terms of the community, so we will knew each other relatively well. The community was very close with many weekly events. My RA also planned activities just for the freshman floor. I knew all of the freshman on my floor and a lot of them are among my closest friends to this day. The dormitory also have a wellness theme, meaning strict alcohol policy. So you don’t have to worry as much about your son hanging out with the wrong crowd. Overall, I think this dorm would be a great fit!
Another dorm I recommend for introverts is the Welch House. This dorm have a quiet theme so people living in this dorm usually aren’t very loud. Hope this helps!
