Gary Matkin - 2/19/2025

Saved My CDL!

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!

This is by far the easiest

This is by far the easiest way to get my lab work ordered and paid for. The phone calls are short and to the point. They don’t try to push extra sales on you and when I walk in to the clinic I simply show my donor pass and with in a matter of minutes I’m done. I will continue to use ADT in the future.
