D.O.T.S. helps businesses ensure safe, federally-compliant, drug and alcohol-free workplaces by providing flexible testing options and exceptional personal service for fast, professional and efficient results. D.O.T.S. was founded in 2000 by Dr. Marcus Vaughn, DC, QME, NRCME. Recognizing a need in the industry, Dr. Vaughn launched D.O.T.S. to offer professional drug-testing services where safety administrators could work personally with experienced professionals to create custom programs that respect and protect each company’s time, money, and testing needs. We follow full federal DATIA protocol on ALL our collections, going above and beyond for every client, no matter how large or small their business is. We are versatile, offering workplace testing that falls outside of drug and alcohol mandates, including fitness and physical capability assessments. And if off-site testing doesn’t work for you, we offer on-site drug testing services that maximize your time and results.
