Greek life does have a strong presence on campus, with one quarter of the student body in a sorority or fraternity. However, because formal recruitment is in the spring, freshmen develop friendships prior to joining a fraternity or sorority, and maintain those friendships throughout their four years. Also, because there is no Greek housing on campus, members of different chapters can room together and with students unaffiliated with Greek life. All of the chapters interact, and very few people, if any, have close friends only from their chapter.
All of this fosters a strong sense of inclusion on campus. Non-Greek members come to philanthropy and social events put on by fraternities and sororities, and the sororities and fraternities are all mostly respected by the campus community for their service and commitment to building sisterhood and brotherhood. Overall, Greek life at USD is popular, but no one is treated any differently based on their decision to rush or not.
