Hi BlueClaw:

This page has a list of resurces for Parish Nursing. It is a start for providing information which you have requested. So far, I have not found national organization for Parish Nurses (like ANA etc).
It is wonderful to see queries on this topic. Are you doing Parish Nursing? I would love to hear how you are involved in this type of Nursing?
In a few weeks, in my local area of Wyoming/Colorado, I am going to a Parish Nursing meeting. I will write about the meeting in this Forum.
