It is great to hear that you are interested in Sigma Pi. I would highly recommend going to our national website and reading our Creed and facts abour our Fraternity. The website is
www.sigmapi.org
As for as what to expect, it has much to do with what you are willing to put into it. I can honestly say that Sigma Pi, as well as many fraternities, offer an opportunity to excel academically, socially, and mentally. You will build friendships that will last forever, and will always have family wherever your life takes you.
Hope this helps, and good luck.
