Tau Delta Phi is a moderately-sized, National Fraternity founded in 1910 at NYU and CUNY. Tau Delta Phi Fraternity is also a member of the North American Interfraternity Conference, and originally joined this prestigious organization in 1922. Tau Delta Phi also holds membership in the Fraternity Executives Association, and in the Capitol Fraternal Caucus, as well as having members in the Association of Fraternity Advisors. Our reputation of a strong National Presence precedes us. We believe in the individually of our members and educational responsibility of our men. What sets Tau Delta Phi apart from other fraternities is that the TauDelt spirit (the guiding spirit of our founders) exists within very closely knit chapters who interact with one another. Each chapter has no barrier of brotherhood from surrounding chapters. We believe that our members own their own education; their education is not our property.  However, we believe that it is our responsibility to help them invest in it. While our members are enrolled in college and it is our responsibility, in partnership with the college, to help guide and mentor to contribute in their social development within their educational process. Our members are in college foremost to grow as an individual, explore outside their world, and gain understanding of its conceptual boundaries. It is based upon this philosophy that we see our Fraternity as a basis for persistence towards graduation. Welcome to the Tau Delta Phi Fraternity expansion website.
