Anybody know about an agency called NurseCore?

I am interested in an agency called NurseCore. If anybody has any information about them-good or bad I would sure appreciate it. Thanks all.
Personally, I've never worked agency. However, my friend has accepted a few assignments from Nursecore over the past couple of years and has had nothing but good experiences.

Thanks TheCommuter. I visited a NurseCore office recently and was very impressed with the staff. They seem like they know what they are doing. The other 2 agencies I visited seemed very disorganized.
