Hi there,
SAI is a GLO for women who have a love of music. It is a social organization, not a professional or service group. This is a common misconception, even among SAI sisters. If you are looking for a sisterhood of musicians and music lovers, SAI might be the place for you. You are permitted to hold membership in both SAI and an NPC organization.
If you're not sure who to contact at SDSU, start here:
http://www.sai-national.org/chapters/deltac.html
The chapter at SDSU is Iota Delta, and that site lists e-mail contacts for the SDSU president, as well as the province officer (kind of like a regional director).
You might also want to check out our Purpose and Mission Statement:

Hope that helps! There are several SAIs on GC (in addition to me) who will be happy to assist you if you have any further questions.
