The company I work for has been with DATCS for the last 15+ years and I have nothing but good things to say for them. The employees are very professional and Brandi in the DOT Compliance department is always my go to person for any and all DOT Drug and Alcohol testing questions. They handle all my testing requirements and the on-site collection service really helps me to stay in compliance with federal testing regulations. The service they provide is fast and accurate and having on-line test results available, it makes it so much easier for me to do my job. I would very highly recommend them for all your regulated and non-regulated testing needs. Thanks DATCS for all the help!!
