So proud of our newest sisters 🤍

This week, we officially welcomed Shelby, Marin, Diana, Ashlyn, Kate, and Sofia into Sigma Alpha. Watching each of you find your place in this chapter has been so special, and we are beyond excited to now call you lifelong members.

Along with activation, our new members received their first set of letters, such a meaningful moment that represents everything Sigma Alpha stands for. Bigs also received their paddles from their littles, making this week even more special and full of love.

Here’s to sisterhood, growth, and the start of something that lasts far beyond college. We’re so lucky to have you 🫶🌿
