To support undergraduates and local chapters, sigma Phi has over 40 men in volunteer leadership roles at the national level, 100 at the local level and almost 6000 living brothers world-wide. The National Society has various scholarship and endowment funds presently available to assist in many ways. Some chapters have their own local scholarship funds.

In addition, the National subsidizes leadership training workshops at national conventions. National conventions are held annually at rotating chapter venues. They offer a unique chance for undergraduates to meet other undergraduates and alumni from all over the country. Regular newsletters called “The Sigma Phi Flame” link all chapters and alumni with each other and the society’s activities.

The sigma Phi Educational Foundation, supported by alumni giving, provides a variety of programs including educational achievement awards to individuals and chapters, loans for renovation and improvement of houses, and grants to students.

Although the national and local chapter organizations are small, all volunteer alumni leaders have a powerful commitment to preserving the Society and building the complete collegian as Sigma Phi has been doing without equal for more than 180 years.
