Hello. I just wanted to warn everyone about Columbia Mailman School of Public Health. Some of the professors are great, but the facilities leave much to be desired. If you want to enroll in the school, you should definitely visit and note the surrounding area. It is full of crime and drug deals. During the day, it is mostly fine. However, if you are going to have evening classes, PLEASE make sure you don't have to walk any further than the closest subway station. Last night, I was walking back to the GWB bus terminal with my classmate after evening class ending at 8:20pm and was verbally assaulted. A black woman who was quite intoxicated, holding a large liquor bottle, trying to get on a bike, screamed at us as we walked by, "GET OFF MY BLOCK WHITEYS!!" I started walking faster, as I was scared of getting a liquor bottle thrown at my head. I've emailed the school but no one cares. If you can go to school in a better area, please do. It's not worth it.
