Sigma Phi Delta continues to grow, more than tripling in size since the year 2000. (Photo from Beta Pi Chapter, Texas Tech University).

It's simple: Alumni financial support allows us to attract, recruit, and retain the best engineering students--the men who will uphold Sigma Phi Delta's strong reputation as the Premier Fraternity of Engineers.

Alumni generosity has helped us to grow exponentially. The Fraternity has more than tripled in size since the year 2000. We currently have 25 active chapters on campuses across North America, and we initiated our 10,000th member last year--thanks to support from alumni like you!

You can help make an impact for our future by making your donation before our giving year ends December 31!

Together, we can ensure that more young men benefit from the life-changing Sigma Phi Delta experience. Click here to make your 2017 donation before the year ends to help us develop even more young men into the next generation of great engineers.
