Realizing the need for better coordination in its fundraising efforts, the Supreme Council on behalf of the Fraternity entered into a partnership with Affinity Connections, Inc. a firm that specialized in alumni relations. Affinity in the coming years would be responsible, amongst other things, for the Fraternity’s public facing website, donor database, mailers and direct marketing campaigns, and working with undergraduate chapters for the creation of content. One visible change was that the STAR, the Fraternity’s esoteric newsletter, would become an electronic publication sent to members with an email address. This version of the STAR would be dubbed the e-STAR and would be sent out monthly on a regular basis in the years to come.

The beginning of 2005 marked the beginning of some trying times for the Fraternity both financially and amongst its volunteer staff.

In 2005, necessitated by pressures within the fraternal world, the Fraternity obtained a General Liability Insurance Policy to cover its undergraduates, pledges, and alumni volunteers. In order to pay for this significant new expense, Brother Featheringham resigned from his position as Executive Director at the beginning of 2005. The Fraternity reverted to operating with a totally volunteer staff, including the reintroduction of the Office of the Executive Secretary which was filled by Alpha Alumnus Levon H.

Brother Mike Golden of Delta Chapter was awarded a $3000 internship to be served through June 2000. Starting February 1, 2000, two additional internships were awarded to Tom Mercer (Epsilon) and Alix Minden (Kappa). Brothers Mercer and Minden assisted the National Office through October 1, 2000.

By 1996, there were several other indications of the major improvements in communications and participation at the National level. One was the coordinating of monthly Supreme Council conference calls by Grand President Scott Everett. Another indicator was the convening of an unprecedented second Supreme Council meeting this winter in the Chicago area, to plan and budget the Third Joint Province Convention. 100% of the Supreme Council was in attendance at both meetings.And thirdly, was the long-awaited publication of the first CASTLE in over two years.

The Province boundaries were changed in January 1, 1990, to balance the number of chapters in each of the Provinces, insofar as possible. The Eastern Province - Central Province boundary, unchanged since 1948, would separate the Canadian Provinces of Quebec and Ontario, descend through Lake Michigan, follow the Wisconsin - Illinois border, then down the Mississippi River to its termination. This change moved Rho Active Chapter from the Central to the Eastern Province. Inasmuch as it has been policy that the principal alumni chapter associated with an undergraduate chapter be in the same Province, Central Illinois Alumni Chapter also moved to the Eastern Province. At the same time, Chicago, Illinois, and its immediate suburbs, was declared an "open city", enabling residents of the area to serve as officers in either Province.

The Supreme Council met in Chicago, Illinois, on March 22 and 23, 1985, to review the status of the Fraternity and to prepare for the Twenty-Sixth General Convention. Of concern was the virtual inactive status of Rho Chapter. Members of the Supreme Council met in Naperville, Illinois, with the two remaining Rho Chapter members and with Rho alumni on March 23, 1985. The attitude and the reputation of the Chapter on the Bradley campus were not conducive to rushing and pledging. The Western Province asked, and received, permission to raise its dues to $20.00 per year. Pi Chapter had retired the mortgages on its two houses in Daytona Beach, Florida, and scheduled a mortgage burning for early May 1985.

Recognizing the impact of inflation and the increase cost of all forms of service, the General Convention, by mail ballot on December 1, 1974, approved the increase in undergraduate initiation fees and National dues, to be effective on January 1, 1975. The initiation fee was increased to $30; the National dues were increased to $30 per annum payable in two installments on April 1 and November 1 of each year. Dues had last been increased in 1967.

Grand President Beals became President of the Professional Interfraternity Conference in Chicago, Illinois, in Mach 1968, for a two-year term of Office. This is the first time that Sigma Phi Delta Fraternity had provided a President for the P.I.C.

Efforts of Grand Vice-President Michael J. Deuel (Eta) and Gene Irvin, expansion chairman of Alpha Active Chapter, were rewarded when a student group at California State College at Long Beach submitted a petition for charter as Sigma Chapter of the Sigma Phi Delta Fraternity.

The long-awaited Song Book, edited by Lyle D. Oleson, was made available to the membership in April 1960. This book combined Fraternity, school, religious, party and patriotic songs into one volume. The book is now out of print, but inasmuch as Fraternity singing seems to have gone out of style, it has not been reprinted.

The Fourteenth General Convention met on August 31 and September 1 and 2, 1961, at the Oak Park Arms Hotel, Oak Park, Illinois, with Delta Active and Delta Alumni Chapters as Hosts. This body extended to Brothers W. Robert McIlvenna and Lyle D. Oleson the gratitude of the Brotherhood for their efforts on its behalf. Suitably engrossed certificates were presented to these Brothers. Minor changes were made in the Statutory Code.

Sweeping changes were made in the functioning of the Fraternity's National Office when new officers took over in 1952. The Ninth General Convention, meeting in Vancouver, British Columbia, with Theta Active Chapter and Vancouver Alumni Chapter as Hosts, elected former-Eastern Province Councilor Robert J. Beals to be the sixth Grand President of the Fraternity. Former-Central Province Councilor John Gray as appointed to the office of General Manager. Steps were immediately taken to incorporate the Fraternity and on September 29, 1952, the Fraternity was at last incorporated under the Laws of the State of California. The incumbent Trustees, who had never functioned in their offices, were asked to resign and men interested in the Offices were appointed. For the first time in the Fraternity's history, the monies of the General and CASTLE Endowment Funds were turned over to the Board of Trustees by the General Manager, whose office had controlled the Funds since their establishment. The first known meeting of the Board of Trustees was held in June 1952 in Los Angeles.
