Community service is a fundamental part of Greek life. But we try to give our new members something more than that. Delta Gammas have fundraisers on campus, such as a fun run and flag football tournaments. All of the money collected goes to their national chapter's selected charity, Service for Sight, Aid to the Blind. They also go twice a year to an elementary school to conduct vision screenings and interact with visually impaired children through face painting and other activities.
Some organizations give to several different charities instead of just one.
Theta Phi Alpha, for example, also sponsors the House That Theta Phi Alpha Built and Glenmary Lay Missionaries. Beggars is sponsoring a softball game in support of a cancer charity. Phi Psi chose Boys Hope as their philanthropy. Some people don't think the organization's occasional involvements are enough. I am sure they do philanthropic activities, but I think they are most commonly known for parties.
