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.

Customer service was surprisingly super helpful and so nice. She was able to get me in at a local location right away the same day. She helped me figure out exactly what I needed. Very impressed.

Time was running out before my Cdl got downgraded because of a violation I had on clearinghouse. I couldn't find an employer to send me for my return to duty test, but these guys had my test scheduled and done in the same day! They saved my cdl. Thank you again!
