Psi Theta Nu is an Alumni organization comprised of alumni brothers of the Gamma Iota Chapter, Sigma Pi Fraternity.

As an alumnus of Gamma Iota Chapter of Sigma Pi at WPI, you are a valued asset to our chapter! We can’t count the occasions in which the active chapter, have benefited because of the tireless resolve of our alumni base. Whether it be mentoring a current member, attending an annual alumni event, supporting the chapter financially, or simply sharing a tale from your time in college, the input of each alumnus is vital to the longevity of our chapter. 


The design for our planned kitchen and dining area renovation is underway.  We are budgeting $100,000 to complete the project which we are hoping to begin during the spring of 2019.

The redesign of the layout, utilities and appliance upgrades will bring us up to latest recommended code and will include:

  • New 6-burner gas stove
  • New convection oven
  • New stainless steel stove hood and exhaust system
  • New two-door reach-in freezer
  • New sinks
  • Much needed additional storage area
  • Replacement of the dining area floor and sub floor

Please consider making a donation to help us continue to restore our chapter House as a place to preserve our legacy!

All gifts up to $10,000 each year for the next 3 years will be matched by a most generous Brother!

We are also very grateful for all our donors.
