I've had to use this service twice for out of state physicians we've hired and both times it was super easy. Both customer service reps I spoke with were super helpful and courteous. I won't hesitate to use their service again if needed.

I use their service for new hire and DOT employee's. Spoke with Taisha Walker this morning, and she was very helpful. She made the process smooth and seamless.
