The customer service from Nationwide has also been great in the three years we have used them.”

"Excellent customer service"

“Sidhu Truck Line Inc. has a need for DOT-FMCSA drug testing for compliance.  Nationwide Drug Testing has served us well in a timely and accurate manner. I have found them easy to work with. They are willing to go the extra mile to answer questions and provide resolutions through knowledge and materials. Their network of facilities makes it easy to get testing done anywhere our drivers may be on the road. I have compared drug testing companies for many reasons and Nationwide Drug Testing far out services and out prices the competition.  Sidhu Truck Line, Inc. has been using Nationwide Drug Testing since 2013.  In my position as safety I know what a tremendous help they have been.  They are effective at managing a challenging task with excellent customer service and they bring a feeing of confidence.”
