If your friend goes to UCR she can contact the Director for Student Organizations, as UCR doesn't have a Greek Director or anyone/an office for Greek Life specifically.

UCR has fall recruitment and COB'ing Winter and Spring quarter at each chapter's discretion.
On a side note, I recently saw UC Berkeley's Sigma Kappa chapter website, and their house. Having been an SK at UCR where none of the greeks have houses, I have to say that I am highly jealous.. it's TO-DIE-FOR GORGEOUS. Mazzeltov, Berkeley Sig Kaps!
