Pam, I joined my sorority as a junior, too. Some would ask why bother, but it was the best choice I ever made! I had lots of personal benefits, but I'll just give you a little synopsis
Of course, I have met some of the most amazing women that I know I would have never known. That's not limited to my chapter, either. I've met women all over the country and have very close friendships with many. I also gained quite a bit of leadership experience. I held several offices both in my collegiate chapter and as an alumna that provided me with many skills that are beneficial in the professional world. I also have a fabulous support system through my most difficult times. There are other ways I've benefitted, but those come to mind first!!
