The Trustees of the Educational Foundation remain committed to providing the funds needed to support the educational and leadership programs for our members on their “quest for excellence.” To accomplish this important goal, we need strong, steady financial support from our many alumni who can attribute at least part of their success to the valuable lessons they learned as members in Sigma Pi.  It is our desire to not only continue to grow this list but to see these donors continue this gracious contribution each fiscal year.

For their generous support, each new member of the Brotherhood of the Golden Cross Club receives a members-only lapel pin. Join the Brotherhood of the Golden Cross Club and help Sigma Pi lay the foundation for the brothers who will become tomorrow’s leaders. For more information, please contact the Educational Foundation at (800) 332-1897 or via email at spef@sigmapi.org.
