On March 17, 1917, five women at New York University Law School took a pledge of sisterhood and loyalty and so founded the Alpha Chapter of Delta Phi Epsilon, the first non-sectarian, social sorority and the only one founded at a professional school. Five years later on March 17, 1922, Delta Phi Epsilon was formally incorporated under laws of the State of New York. On December 5, 1922, stretching out to international boundaries, the first Canadian chapter was installed at McGill University in Montreal, Quebec. Growth has been steady, but expansion in numbers has never been favored over strengthening within. From this small group making up the first chapter, there are now more than 25,000 members with chapters throughout the United States and Canada. Our chapters, both undergraduate and alumnae, enjoy a distinguished reputation for scholarship, service, and leadership.
