When a sorority closed at Allegheny College in the late 1970s, Panhellenic sought to fill a void. Alpha Delta Pi was colonized with 44 charter members. It was the first new sorority on campus since 1926. The chapter has a suite in an all-women's dormitory. The chapter has maintained the same fourth floor suite since the late 1980s, following a time when the suites were rotated. The sorority suites are special as that is where the women wait on balconies to be pinned by their fraternity sweethearts. The chapter won first place in Greek Sing for five straight years and has been selected Outstanding Panhellenic Chapter several times. Eta Beta participates in Allegheny's "Run-Out Day," a special event when bids are extended following formal recruitment. The excitement of presenting new members makes this Eta Beta tradition an unforgettable one. Clemence Mershon, Alpha Delta - Colby College, is a long-serving advisor. Kirstin Dolan has served as an international officer for many years and on Grand Council.
