 Delta Upsilon at Dartmouth College was originally founded as Epsilon Kappa Phi , a local fraternity , at Dartmouth College in 1920 . In 1926 , the local fraternity became the Dartmouth chapter of Delta Upsilon , a national fraternity . The fraternity dissociated from the national in 1966 , and adopted the name Foley House . Foley House was one of the six local Greek organizations that became coeducational in 1972 . In 1984 , the organization decided to drop its association with the Greek system entirely and became one of the Affinity Housing programs offered by the college , available to any student interested in cooperative housing .
