I don't know why they are considered top tier. I watched one of these girls pee on the side of mcdonalds. They are very hit or miss in the looks category. Some are gorgeous and some are terrible looking. Probably the least classy sorority on campus at this point. They just have a ton of money.
commenter below. DDD is not that involved. They may contribute a lot of money to their philanthropy, but my bet is "daddy" helps out a lot there. Actually, they do very little to support the other houses and are not that active.
These girls are incredible and seem to have a great since of what friendship truly is. All of them work hard to keep good grades, participate in other things on campus, and they are more involved with their philanthropy than any other sorority on campus.
Yes, tri delt everywhere is top tier. However, these girls are not nice at all. They are so rude. During go greek round, a girl asked me what my parents jobs are? Like for real. All they care about is money.
