I met 1 travel nurse that loves Cirrus. I would sign on with several companies because the jobs are tight now and this will increase your travel options. Clinical One, RN-Network, are good.
Private message me for my recruiters names. right now I'm with Medical Solutions and I like them alot but they don't have alot of assignments.
Read the reviews section, click on companies and you will get an idea of who to avoid....
Where do you want to go?
