Welcome!

In 1917, Sigma Delta Tau’s seven founding sisters at Cornell University experienced discrimination practiced against religious minorities by many Greek Organizations.  In response to the closed doors, these bright Ivy League Jewish scholars established a sorority which would represent the individuality of its members and empower young women to meet their full potential. Today, Sigma Delta Tau honors our Jewish roots, but its doors are open to all as a social organization based on College Panhellenic Guidelines.

SDT, a National woman’s social sorority, has over 100 chartered collegiate chapters and more than 60,000 alumnae members.  SDT’s philanthropic partners include:  Jewish Women International, Prevent Child Abuse America, and Women for Women International.  Sigma Delta Tau provides intellectual, philanthropic, leadership and social opportunities for all members, presented within a framework of mutual respect and high ethical standards.


SDT Alumnae Directory FAQ

The Sigma Delta Tau Foundation is sponsoring a new SDT Alumnae Directory to be published in 2015. This is a great opportunity for alumnae to update their information in order to maintain your connection with your sorority. Our vendor, PCI, will be reaching out to all alumnae throughout Spring and Summer 2014. We encourage you to make sure your information is correct, as it not only will affect what goes into the directory, but will be used to update your records at the National Office. While we encourage you to consider purchasing the directory (book or CD), that is not required as part of the information update process.
