I have been a nurse for almost 14 years now.  Its a very rewarding profession. 
I agree, you must be big help to ndividuals, families, and communities around you.
I try to be. I've had jobs from the NICU, community health nurse, Pediatric nurse, and home health surpervisor.
So you must be quite experienced in providing home care to patients of all ages.
Yes, I was actually a nursing supervisor over a bunch of nurses who did home health care.  My favorite job was working as a nurse in the NICU with the tiny babies.  Its amazing how far medical technology has come that we can save the lives of tiny ones.
So would you say you are mostly working collaboratively with physicians?
