Have you checked the national websites of the sororities with chapters at the school you'll be attending to see if they have alumnae clubs/chapters in or around Boston? I did two quick gooogle seaches -- "alumnae boston alpha" and "alumnae boston kappa" -- and pretty quickly found what appear to be links for alumnae groups for at least 15 of the 26 NPC groups.
I am totally new to the Greek system/idea of rushing, but from what I have heard and read online here it seems as though my school does require recommendations.
Thank you for your suggestion! I found a few local alumnae clubs this way, but I cannot seem to locate all of them. Thanks again!
Have you asked the girls that you know that went thru recruitment recently where they got their rec letters from? Make sure to ask teachers, have parents ask co workers, ladies from your church, your friends parents.. you would be surprised at where you can find ladies willing to help you out!
