Following the amalgamation, the United States was divided into districts and, by 1930, enough members had graduated from medical schools allowing for the formation of graduate clubs. In 1926, an Endowment Fund was started giving the Fraternity long-term stability. In the 1940s the Aaron Brown Lectureship Program was begun and has remained a vital chapter event through the years.
In the late 1960s, the Fraternity opened its membership to women and encouraged recruitment of medical students of all races, nationalities and religious beliefs. The past 25 years have seen the Fraternity's membership become wonderfully diverse, reflecting the diversity of the medical profession today. The addition of the premedical affiliation in 1994 rounded out the Fraternity's membership, which now spans an entire lifetime of medical education and practice.
PhiDE celebrated its 100th anniversary in 2004 as a strong, vibrant, professionally directed organization headed for new growth and great excitement. The 21st century beckons us, and we continue to operate under Aaron Brown's guiding principles of Philanthropy, Deity, and Equity.
Phi Delta Epsilon has grown from a small insular group to a diverse, all-inclusive organization. We have done this by making our motto live: Facta Non Verba, Deeds Not Words. And, indeed, we will continue to prosper, grow, and spread the warmth of our fraternalism into the future.
