Who We Are

Delta Sigma Delta is an organization of dentists and dental students brought together with the common goal of promoting excellence in the dental profession. We currently have 33 dental school chapters, and 42 alumni chapters. At the school level, members have a great study support group, social events, education opportunities and do community service projects. Fellowship continues at the alumni level in graduate chapters all around the country.

On November 15, 1882, seven dental students in Ann Arbor, Michigan met and founded the first dental fraternity in the world. For a name, they transposed the initials of the DDS degree, to DSD and substituted the Greek letters ΔΣΔ. Delta Sigma Delta was born and this new chapter became known as Alpha Chapter. Upon graduation, these these men continued their bond by creating the Supreme (or Alumni) Chapter, from which developed the many Graduate Chapters. After 130 years, we are 75 chapters strong in the United States, Europe, Canada and Australia.

A message from our current Supreme Grand Master:
Christopher A. McConnell, DDS (Denver, CO)

Welcome to the Delta Sigma Delta International Fraternity Official Website. As the Supreme Grand Master (International President), I welcome members and guests to the information you need regarding the Delta Sigma Delta International Fraternity. In additional to overseeing the business and functions of the fraternity, I have the honor of travelling to our many chapters throughout the world including Europe, Australia, New Zealand, Canada, and the United States.

As a student at the University of Colorado, I was initiated my freshman year into the Alpha Delta Chapter of DSD at CU Dental School, fall 1982. Many of my closest friendships in dental school came from “Delta Sig” with many more after my graduation. My private practice and teaching responsibilities have been affected and influenced by many Delta Sigs over the years.

Our newly re-formed graduate chapter, in Denver, continues to serve as a source of professional interaction, continuing education and camaraderie as well as a supporting and mentoring function for the Delta Sig dental students at the University of Colorado.

Don’t have a grad chapter in your area or one at your dental school? Ask us for help as we continue to open new chapters each year.

I look forward to meeting many more Delts throughout the world during my travels as Supreme Grand Master.

Most of us remember those days in dental school when financial aid meant a great deal to us. Today's Brothers and Sisters of Delta Sigma Delta have the same problems, and this is where our Educational Foundation is able to help out. The Foundation currently has 29 loans issued to students with principle due of $255,000. In addition, $15,000 in grants are given annually to help finance student activities fraternally, professionally, and for educational purposes. It is anticipated that many more applications for loans will be received this year and thereafter. Your contributions will allow the Foundation to continue to aid our DSD students.
