  1. What about Sigma Alpha Iota?

    1. I opted to make this a blog about the Greek social organizations in Potsdam - so I'm not include SAI, Gamma Sigma Sigma, Alpha Phi Omega and the other organizations that are not part of IFC/ISC/AGC.

    2. Both SAI and GSS have been voting members of AGC

    3. Do they participate in the same rush with the social sororities? Meaning....does someone who opts to join SAI or GSS have to also visit Omega, Zeta, Phi K, etc. in order to get a bid?

    4. Both SAI and GSS are jokes. they arent even real greek houses. i dont get how potsdam is allowing new houses on campus but wont fix the banned houses

    5. Even if SAI or GSS don't have a house, doesn't mean shit. Banned houses are banned for a reason, are they not? If they do or don't want to participate in Formal rush, that's their choice but it doesn't mean they don't have value or aren't a real organization.

    6. Wow! That is pretty harsh to call SAI and GSS "shit". That is not at all in the Panhellenic spirit! And what would you call them if they joined the AGC? All of a sudden they aren't "shit"? Is that how you feel about PMA?
      Both GSS and SAI have done a lot for their community and the country. These are international organizations that help people in need and support various ideals. No Greek organization is "shit". I do hope you truly do not feel this way.

    7. It's a little disappointing that SAI, GSS and APO don't make the grade here... just because they aren't "social" organizations. I was in GSS, and we did a LOT of good community work. It was the '70s, and while many of the more social organizations were just about drinking and partying, we did some good while still having a good time. My daughter is now in APO in another SUNY, and is having the same experience - learning leadership and serving on an executive board, doing community service, and making great friends. Please don't knock these groups just because we didn't have a house.

    8. Sigma Alpha Iota is a Professional Women's Music Fraternity. Just because it is not social, doesn't mean it's any less than other organizations. They are not, nor were they ever banned. They do not do formal rush because they have their own method. Do not call an organization "shit" because they don't do something the same as everyone else.

  2. Theta Phi Alpha's nickname is Theta Phi, not Theta. Theta is the nickname for the national NPC organization Kappa Alpha Theta.

  3. How come there are no multicultural greek letter orgs in Potsdam. How come what you display on this site/blog are Caucasian orgs. diversity?

    1. Does Potsdam have enough students to support a race/culture-specific Greek social organization? If it did I suspect someone would start one. AEPi is a Jewish fraternity but I don't recall that being a focus of the chapter, at least not when I was there. KDChi is Hispanic, but I don't think that's a focus of the chapter in Potsdam.

    2. Just because the organizations listed are historically caucasian, doesn't mean that there isn't diversity today. If you look at the demographics today, there are more and more racial & ethnic minorities joining these organizations. One thing I can say about the Greek organizations in Potsdam is that they are pretty open to people of all backgrounds regardless of skin color, ethnicity, sexual orientation, etc.

      FYI: Diversity isn't achieved only through race & ethnicity. The differences that can be celebrated amongst people can go deeper than skin.

      Also, just recently a few guys founded a new chapter of LSU, a national hispanic fraternity. Progress is being made on all fronts.

  4. I think it would be wonderful to also hear about Alpha Phi Omega at Clarkson and Potsdam! As well as GSS and SAI. This site is called "Potsdam Greeks" and these organizations are also Greek. Why exclude them because they are not as social as the other organizations on campus?
    I love reading the posts on this site, but these others organizations and their alumni probably feel even more isolated. Since Potsdam Greeks are on such rocky terms, it seems we should focus on uniting all the Greeks on campus rather than exclude some.
    Again, I love this page! There is another Potsdam alum that has a history blog and sometimes mentions Potsdam groups. I hope we call all become more unified because all these groups help our community!

    1. Thank you! Just what I was thinking, as a GSS sister, married to an APO brother, who are now parents to an APO brother on another campus.

  5. Sigma Delta lost its recognition in 2015
