Very glad to see this question being addressed, I asked the same qstn few months ago and noone ever replied.
I am a recent 2 yr RN grad in AZ and stopped by my local Fresenius clinic, it's very small and the nurse mgr spoke to me for a long time, answered many qstns, was very helpful and really nice. I watched her interract w/ some staff and got a small sense of the workplace culture.
She told me that b/c of Medicare changes last yr or so, they could not begin to train me until I had almost 1 yr of RN work behind me. I felt that she would send me to training tomm but could not, I'm really mad about this work requirement and I suppose that all dialysis co's that take Medicare will say the same.
I was kinda planning on this training but will have to wait many months now, and hope that I have RN work in the meantime, now that the country is in this ugly depression.
