In 1958, the size of the Executive Board was increased to include the "AA", "CC", "DD", the immediate past "AA", and Regional Representatives called Regents. More important than the increased size was the method to be employed in selecting its members. As before, the "AA", "CC", and "DD" were chosen by the Convention. Included in the change was the adoption of a plan whereby regions were established and a Board member selected from each region. Prior to the adoption of this plan, every member of the Board could possibly have come from the same community or geographical area. The new plan made this impossible; the entire Board benefits from the geographical diversity.

In 1960, the Fraternity employed its first, full-time executive, Harold "Buc" Buchanan, Wisconsin '35. Up to this time the Fraternity was run by volunteers or part-time employees. At the 1960 Convention, a "Building Loan Fund" was created. The original level of assessment proved too low and, in 1962, the Delta Chi Housing Fund was established to assume the function of the "Building Loan Fund." Today, the Housing Fund has loans outstanding to chapters and colonies across the country.

Also at the 1962 Convention, the Regional Representatives were redesignated as Regents and the Executive Board was renamed the Board of Regents.

In 1969, the Fraternity moved out of rented space into its first permanent facility. The property is wholly owned by Delta Chi and houses the archives of the Fraternity and a staff of three directors, five traveling consultants and three clerical employees.

At the 1975 Chicago Convention, the Order of the White Carnation was created to honor alumni who give outstanding service to the Fraternity in a meritorious but inconspicuous way. The first inductee into the Order was Victor T. Johnson, Purdue '32. In 1983, Senator Henry "Scoop" Jackson, Washington '34 was selected as the first Delta Chi of the Year in honor of his achievements in his chosen profession.

While there have been a variety of changes that have strengthened Delta Chi within the last decade, the 80s will most probably be remembered for the growth in chapters. Starting with 78 chapters and colonies in 1980, the Fraternity celebrated at its Centennial Convention with 120 chapters and colonies on the rolls.
