The Eta Delta Chapter of Sigma Pi at Cal Poly has a strong and influential alumni network. Being apart of the brotherhood of Sigma Pi does not only last the four years of college; the connections of brotherhood are shared for life. Although brothers come and go through Eta Delta, alumni continue to keep strong connections with the chapter. Every year, the Eta Delta hosts our Alumni Weekend for any and all alumni that wish to attend. Events include rounds of golf and group dinners downtown.

The advantages of our rich alumni network cannot be understated. Connections in the business world through brothers of Sigma Pi provide opportunities for our graduates to hold fulfilling careers in compelling job positions. Through our alumni network, the brothers of Sigma Pi are able to make a positive impact on our world by the strong brotherhood that they will share for life.
