Two other sororities, Chi Omega and Alpha Phi, and the fraternity Delta Tau Delta, used to have chapters at Willamette. In the mid-1990s, Delta Tau Delta lost its charter. The two sororities lost their charters after their move to sorority row. Chi Omega was transformed into a multicultural oriented residence known as WISH (Willamette International Studies House). In the spring of 2014, Alpha Phi accepted an invitation from the university's Panhellenic Council to reorganize their chapter on Willamette's campus. In the fall of 2014, Beta Theta Pi began recolonization of its chapter on Willamette's campus with the consent of the university's Inter-Fraternity council.
