I moved your post to its own thread in this fourm.
Good to read of your interest in the legal nursing career.
No, I never did any phone investigaion prior to doing the career. Many do and I advise that you do. Will give you a feel of what is needed in your own area.
As for where you do the work? My office is in my home. So, most of anything I do is there. But, I do go to attorney-client's offices when needed.
Not sure what you are asking about healthcare insurance? You mean medical insurance coverage (healthcare) for you and/or your family? I cannot answer that question.
If you have other questions/concerns about the legal nursing career, please post here. I will be happy to assist you.
Good luck with your future plans and decisions.
