I have traveled with access nurses. I worked prn for them in the San Francisco bay area last summer. I had some trouble with them. Housing was great, but since I worked prn with them I did not have a set 36 hour guarantee. I was to schedule my 3 shifts a week and they tried to set them up for me within 7 different facilities in the bay area. I was canceled every shift I wanted and ever other day for that matter for the first two weeks so I ended up getting out of my contract. I think if you worked with them and do a contract 36 hour guarantee then you should be fine but I really don't recommend doing their PRN bit.
