Hey B.R. As Epstein noted, I see they have an office out of Atlanta; however, looking at their website, it does appear as if they are part of a larger organization that places nurses here, stateside, and overseas. This may have advantages and disadvantages. If the Atlanta office is the only office in the states, then that may limit the number of assignments they have available.
I have not heard anything negative about them and although they are not accredited by the Better Business Bureau, they do carry an A+ rating by the BBB (which just means that no one has filed a report with the BBB in the past three years).
They do appear to be on the smaller side as far as travel listings and as I mentioned before, this would limit your choices if you were traveling with them exclusively. The reason I say that they appear on the smaller side is because they currently list 579 travel opportunities here in the U.S. By contrast, Cirrus Medical Staffing just sent out an email to their travelers stating that in one day, they received almost 200 assignment listings (in addition to the ones they already had).
When you have a smaller company, you do tend to find that they are more attentive to their travelers, but the only way to know for sure, is to travel with them (or speak with someone who has).
It certainly would not hurt to join up with them and see what they have to offer when you are looking for assignments. However, I always tell travelers to sign up with at least a few companies to open themselves up to more assignment offerings.
I do have a list of recruiters I work with, at several of the travel companies I included in my book and also currently recommend to travelers just starting out. If you'd like, you can email me at david@travelnursesbible.com and I'll give you the contact information for the people I use when searching for assignments.
I hope this helps and feel free to email me at the aforementioned address if you have any other questions.
