Founded in 1899, Alpha Sigma Tau is a national sorority for women, dedicated to promote the ethical, cultural, and social development of its members. This sorority has close philanthropic ties to the Pine Mountain Settlement School in Harlan County, Kentucky as well as Habitat for Humanity.

They are your roommate, your neighbor down the hall, a classmate or a friendly face in a sea of strangers on campus. Look for them studying in the library, volunteering for local charities, working on campus, shopping in the city and proudly wearing their letters.
alpha sigma tau girls are gorgeous, intelligent, and definitely know how to party ;)

Alpha Sigma Tau has the sexiest wildest girls in it. If you are not out with at least 1 of them, you are not having as good of a time as you could. They are down to earth and crazy. There is NEVER a dull moment when you are with these chicks
One time my room got ransacked by 4 hot AST's and the spent 4 hours of a saturday night dancing a screaming in my room. A large blow up blimp I had was been tossed around and ridden. MY bed had multiple beers spilled on it and footprints on it from people jumping on it. I just sat back and watched in pure exstacy laughing! They were so funny!
