Greek life is pretty strong and involved in campus life. It is hard to walk around campus and not bump into someone involved in Greek life. The Greeks care deeply, often doing service or caring for their brother/sister chapters at another school. When the Delta Sigma Phi house burned down at Illinois State University, the Delta Sigs from Millikin had a 24-hour "podium stand" to help raise money. Greek Week also occurs on campus, and that's when you'll really see them participating. Members of the fraternities and sororities are usually nice, and they are not snobby. Typically, people believe that people within Greek life are stuck-up or not intelligent, but those are the stereotypes. It is all a matter of knowing the person and not simply the fraternity or sorority.
For housing, most Greeks have a house. By Weck and the New Halls, Sigma Alpha Epsilon and Tau Kappa Epsilon have their houses. Pi Beta Phi and a few of the other Greek houses are across the street from Leighty-Tabor Science Center, and Tri-Delta is a little farther from campus. A few organizations, such as Sigma Lambda Gamma, do not have houses, so members are allowed to remain within the dorms or wherever they take residence.
