On November 26, 1984, the first female Greek organization at the Milwaukee School of Engineering was established  from the Tau Iota Epsilon Fraternity and Triangle Fraternity Little Sisters Program as Phi Delta Chi Sorority, Alpha Chapter. The purpose of this organization is to provide the women of MSOE with an opportunity to enjoy the benefits of the Greek system, to promote women in engineering and management and provide a wide range of social activities for it's members. Our colors are red, black, and gold. Our symbols are the dove, rose, and heart.

Phi Delta Chi is a social sorority. We participate in annual activities such as Homecoming and St. Pat's, in addition to a number of intramural sports. We work together with other Greek organizations in order to organize gatherings and social events. We provide support for one another as needed in scholastic and social situations. We also do community events in the form of educational and philanthropic projects. Some past projects include: American Heart ball, feeding families at local kitchens, Habitat for Humanity, blood drives and various Ronald mc Donald charity events. We also have a few traditional activities such as our annual flower sale, car wash, and summer camping trip.
