The Delta Epsilon chapter of Delta Delta Delta started out as ΧΣΦ, a local sorority. On May 25th, 1912, Millikin's Delta Epsilon chapter of Delta Delta Delta was established. Since that date, over 2000 members have been initiated into the chapter.
Tri Delta's current chapter house was built on Millikin University's campus in the 1950s and has since been expanded twice.
Jodi Benson, the voice of ARIEL AKA The Little Mermaid, was a member of the Delta Epsilon chapter in the 1980s.
