Employee drug testing and occupational health for Greenville employers

DOT compliance, pre-employment screening, and on-site testing for trucking, school districts, manufacturing, and construction across Hunt County.

Trucking companies and owner-operators

Keeping drivers road-legal means keeping paperwork current, and a lapsed medical card takes a truck off the road the same day. Drug Testing of Texas handles the full DOT cycle in one Greenville location: DOT physicals performed by an FMCSA-certified medical examiner, pre-employment, random, and post-accident screening, and breath alcohol testing. Owner-operators and small fleets who need random pool membership can enroll through our DOT consortium program, which handles selection, notification, and recordkeeping so you aren’t tracking it on a spreadsheet. Walk-ins are welcome for most services and we open at 7:30am, so drivers can test before a run rather than losing a day. We also run non-DOT panels for staff outside safety-sensitive roles.

Concrete and construction

Job sites move, and sending crews across town to a clinic costs more in downtime than the test itself. We bring testing to you — on-site collection at your site or yard for an added fee, which makes sense for crews of any real size. When something happens on site, post-accident testing is time-sensitive, and we accept walk-ins so you aren’t waiting on an appointment slot. For new hires, pre-employment physicals and drug screens can be scheduled same-week, and we handle both DOT and non-DOT panels depending on the role. Concrete operations running CDL drivers on mixers and haul trucks can combine DOT physicals and driver testing under the same account rather than splitting the work between two providers.

Manufacturing and industrial

Plant environments carry exposure risks that a standard drug screen doesn’t cover. Alongside pre-employment and random drug testing, we provide the occupational health services manufacturers actually need: spirometry for lung function, audiometry for hearing conservation, respiratory fit testing, and digital X-rays. Running these through one provider means one relationship and one set of records rather than coordinating a clinic, an audiologist, and a lab. Pre-employment physicals can be built around the physical demands of the specific role. We also order through FormFox and eScreen, so if your corporate program already routes tests electronically, we can receive them without you changing systems. Employer accounts and ongoing programs are available for plants testing on a regular schedule.

School districts

School bus drivers hold CDLs, which puts districts under the same federal testing and physical requirements as any trucking company — often without a dedicated compliance person to manage it. We handle the driver side end to end: DOT physicals from an FMCSA-certified examiner, pre-employment, random, and post-accident testing, and random pool enrollment through our consortium program. For non-driving staff, we run pre-employment physicals and non-DOT panels. Districts hiring in batches before the school year can schedule groups rather than sending people over one at a time.
