Championing High Safety Standards
Reliable Screening for Local Workforces
Founded on Family, Committed to Safety
A Mission to Improve Workplaces
Demi Group Toxicology Screen came into being through the determination of family members who understood that safer workplaces begin with a commitment to responsibility and reliability. Our story is rooted in Houston, where our founders saw firsthand how important it is to create environments where people can work without concern - for their safety or the accuracy of their health testing results. Working together, our family built an organization that reflects the values learned from generations of hard work and care for community. Every service we provide exists because we believe that employers, employees, and organizations deserve access to honest, thorough, and confidential drug screening around the clock.
From the start, our motivation has never been purely business - it has always been about making a positive difference, ensuring that the tools for safety and compliance are available when needed, no matter the hour. Our approach combines personal attention with the standards of a professional healthcare provider. With a welcoming, accessible facility and a team of certified experts, we promote trust while supporting Houston's vibrant workforce. We believe reliable testing brings peace of mind not only to companies, but to families and neighborhoods throughout the community. That is the heart of Demi Group's mission.
