Greek life

I’ve heard that greek life is a big part of student life and that if you aren’t a part of one, you won’t have much to do.
I wasn’t planning on joining greek life so I was wondering if it’s still possible to have fun and socialize without it?
Also I’m not a big partying type. I just want to make sure I have the opportunity to make friends and socialize.

SSU is not a big party school, check out this thread: https://www.reddit.com/r/SSU/comments/60bfg3/how_are_parties_at_sonoma_state/
