A Pioneer of Workplace Drug-Testing

rectangle divider

After a long career in Human Resources and workplace healthcare, Tom Allen enthusiastically embraced the challenge of helping companies regulated by the U.S. Department of Transportation and the U.S. Nuclear Regulatory Commission implement drug and alcohol testing programs to comply with regulations signed into law by President Ronald Reagan.

His company has been committed to improving the greater public safety and a strong and vibrant workforce by encouraging employers to build and maintain drug-free workplaces. He established Tom Allen Enterprises in 1991, quickly becoming a leader of the drug-and-alcohol-testing industry and a trusted name by companies seeking to be compliant with federal and state regulations.

The Tom Allen team’s secret to success was simple: its members recognized no two companies are alike and they concentrated on clearly understanding their clients’ unique business needs.

Today, from its headquarters in Holland, Michigan, Tom Allen’s reach extends into industries with global impact. Clients can count on having swift and personal contact with a highly experienced program administrator who understands their company and can step in on a moment’s notice to help navigate day-to-day concerns and extremely difficult situations that can profoundly disrupt any organization.

Workplace Safety & Employee Wellbeing

Employees who are not abusing substances are generally happier, healthier and more productive, while those who are can be a danger to themselves and others. Helping to keep your workplace safe from the harms of drug and alcohol abuse is good risk management — and it also can help attract and retain quality employees.

Drug Testing for Business Opportunity

We can help companies grow into new and bigger business opportunities by creating and managing drug policies and testing programs that are the best fit for their unique needs. We also help our clients avoid violations of federal law that could put them out of business.

Drug Testing for All Companies

Tom Allen Enterprises works across industries with companies that are mandated to follow federal laws — and those that are not, but want to maintain drug-free workplaces. We collaborate with a diverse spectrum of companies, catering to the unique needs and challenges inherent in each business.
