BruinGirl, I am locking this thread as we usually do not discuss "strength" of chapters in terms of popularity and things of that nature on these boards. From what has been said on the forums, it seems that the Pi Phis at UCLA are doing very well. Maybe you could check the Pi Phi website to see what awards the chapter has received in the past few years. That will give you a sense of how they are doing. Also maybe you could get involved volunteering and find out that way.
Welcome to the boards and I'm sure you will represent Pi Phi in a fitting way here.
