I don't know about professions but as far as SKILLS go:
I'd say anyone who helps out homeless, unwanted, needy animals. I just think they're absolute SAINTS for "helping creatures that can not defend themsleves."

I also think people who work with organizations like: missing children, orphanages, homeless shelters, food pantrys, etc. deserve appreciation!

I think guster girl had a good point too!
