Our Philosophies and Policies

Our philosophy of providing superior and personalized services is based on the training our owner received at the Baylor College of Medicine while conducting research studies for pharmaceutical companies. These studies required compliance with very stringent and precise Federal Drug Administration (FDA) regulations which included Chain of Custody for specimen collection. Our corporate philosophy encompasses the sensitivity, seriousness and potential repercussions of drug and alcohol testing at a level which far exceeds the practices generally followed in this field. Our standards, policies, and procedures are those set forth by the Department of Health and Human Services / Substance Abuse and Mental Health Services Administration (DHHS / SAMHSA) and the Department of Transportation (DOT), and are adhered to by us for all our clients. Our staff members, as well as the personnel located at clinics are trained in and committed to this high standard of excellence.
