Scott Wright
Scott Wright is the Vice President of Student and Administrative Services, which is the umbrella office for basically everything you interact with on a daily basis that isn't a professor. He's actually a very approachable and nice guy, despite heading the offices that tend to get the most flak from students, such as Housing, Dining, and Columbia Mail. He is from California.
FYI - he likes hockey, so find an excuse to talk to him about it when you see him. Unless you know nothing about hockey, in which case say nothing. (Note: when he does find an excuse to talk about something, he will talk A LOT. Avoid getting him started if you are meeting with him to get something accomplished student government related)
