"Sisterhood is the essence of all the wisdom of the ages, distilled into a single word. You cannot see sisterhood, neither can you hear it nor taste it. But you can feel it a hundred times a day. It is a pat on the back, a smile of encouragement. It's someone to share with, to celebrate your achievements."

• Presents: Every year during Trojan Parents Weekend Tri Delta presents their new pledge class with a beautiful brunch and ceremony held on our front lawn. Each girl is presented to the parents by the President and New Member Educator. This is a highly anticipated event by all of our new members because it gives them a chance to show parents what Tri Delt at USC is all about!

• Pearl Sisters: After receiving a bid to Tri Delta, each girl is given a Pearl sister, a girl who serves as a temporary big sister in the sorority and helps the girl get acclimated to Greek life. Pearl sisters are a great way for new members to get to know older girls in the house and learn about some of the great benefits Greek life can offer!

• Bigs/Littles: Once Tri Delt has gotten to know each New Member better, each girl is given a permanent "Big," an older member in the house who serves as not only a resource for anything and everything the New Member would need to know, but as a friend to study with, go out with, grab dinner with, or even study abroad with! This long-standing tradition forms great bonds between the different grades in Tri Delta, and has resulted in many strong friendships being formed!
