The ETDT Program


In 2003, Dr. Keven Ellis established East Texas Drug Testing (“ETDT”) in Lufkin, TX.  Dr. Ellis is a local chiropractor who saw a need and wanted to assist the local schools and area businesses throughout Angelina County, including Lufkin, Diboll, Zavalla, Nacogdoches, Center, Livingston, Jasper and other surrounding areas to create and maintain a Drug-Free work environment.  

ETDT provides a confidential, cost-effective drug and alcohol testing program, including DOT and Non-DOT physicals geared toward everyone from an individual, small business or a large corporation - all with excellent customer service and dependability.  

We provide federally mandated testing for the transportation, marine, aviation, pipeline and oil and gas industries.  Complying with federal and state rules and regulations related to testing requires a lot of time and effort. Many companies are not equipped to deal with ever-changing federal regulations and state legislation affecting the testing industry. Companies can take advantage of the Third Party Administration (TPA) services provided by ETDT. Internal programs offered by a company can be charged with discriminative administration, unfair treatment, and wrongful discharge. Contracting with the experts at ETDT is a simple decision that can help protect your business.

ETDT collectors are HIPPA certified as well as DOT drug and alcohol certified collectors. ETDT is a member of Drug and Alcohol Testing Industry Association (DATIA). ETDT collectors have received 12 hours of specialized training for specimen collection techniques in compliance with federal testing regulations. In addition, Dr. Ellis is certified to complete DOT physicals and is currently registered with the National Registry of the Certified Medical Examiners.
