J C On-Site Testing LLC is a Wisconsin-based mobile drug and alcohol testing and DOT compliance company serving employers, individuals, families, attorneys, and organizations throughout Wisconsin and surrounding states.

With more than a decade of experience in drug and alcohol testing, we provide convenient mobile testing services including urine, hair follicle, oral fluid, breath alcohol, DNA, instant and laboratory-based testing. We also help employers navigate the often-confusing world of DOT compliance through consortium/TPA management, Clearinghouse support, DOT drug and alcohol program assistance, supervisor training, reasonable suspicion training, and compliance consulting.

Our goal is simple: to make drug and alcohol testing and compliance easier, more accessible, and less disruptive for the businesses we serve. Rather than asking employers and employees to work around a traditional testing facility, J C On-Site Testing brings professional collection and testing services directly to the client when and where they are needed.

We believe compliance should be more than checking a box. It should protect businesses, employees, and the communities they serve. Through education, practical guidance, and dependable service, we come alongside employers to help them build and maintain effective drug and alcohol programs while meeting applicable DOT and workplace requirements.

J C On-Site Testing is proud to serve businesses throughout Wisconsin, Illinois, and Minnesota directly, with the capability to support clients nationwide through our network of trusted collection partners. We take a personal, relationship-focused approach built on professionalism, education, integrity, and service.
