Men in Suits

Donations and the Alumni Dues program provide a vital source of operational funding for the Society. Our ability to keep alumni informed and engaged and, at the same time, maintain strong relations with undergraduate chapters, is dependent upon alumni contributions.

If you wish to make a general donation or dues payment to the Society then this is the right avenue! Contributions to this fund offer the most flexibility to Sigma Phi and cover programming of all kinds, as well as the general operating expenses of the Society.


Contributions to this fund are not tax deductible.



The Sigma Phi Educational Foundation provides financing for educational programming. The Foundation funds numerous academic achievement awards, speaker programs, direct faculty interactions with the undergraduate chapters, and in 2015 funded the implementation of sexual assault prevention and bystander intervention training for all undergraduate members.


As an educational foundation under IRC Code Sec. 501(c)(3), contributions to the Sigma Phi Educational Foundation are tax deductible.



The Sigma Phi Educational Foundation Thorsen House Fund provides a way to make a tax deductible contribution for the maintenance and preservation of the Sigma Phi Thorsen House, a National & State historic landmark.  All donations to the Thorsen House restoration fund are used for the benefit of physical house restoration projects that sustain the original architecture of this historic structure.

By making a contribution to one of the funds listed above you are helping to ensure the traditions, values, and virtues of the Sigma Phi Society are continued for future generations. Online donations are a quick and easy way to make a donation using a secure credit card transaction.
