Client Reviews

Hear from some of the organizations that trust STS to manage their testing programs.

"I needed a court ordered drug test from out of state. I called the first place on Google and it was an hour wait. The second place was not a local company and put me on hold.. The owner stayed late for me, and was completely understanding. Love them. Everyone in the Richmond area needs to be using Secure Testing Services for their drug testing!"

Janet Abrams

"As a Third Party Administrator for a large trucking company, Steve and his team are my go to for on site testing on the east coast as well as any job fair or hiring event testing. Steve is prompt with communication, always friendly and willing to help. Secure Testing Services has frequently gone above and beyond to assist my client in getting the testing they needed and is very knowledgeable of DOT regulations and testing procedures. Highly recommend them!"
