Professional Sororities/ Fraternities?

[anongreek]

There are several of you who seem to be a part of many professional fraternities that I have never heard of, which had me curious!

I am involved in a business professional fraternity through my college, but I was wondering what other types there are (these very specific - major focused - fraternities are all that I have ever known of, outside of NPC greek orgs), and if there are any that primarily focus on community service and philanthropy. I love my business fraternity, but the focus is not really on philanthropy, and more or less on networking (which has also been very helpful).
I am just interested in more opportunities to give back to my community.


Thanks for any info you provide!!
