Who we are

Our story began nearly 40 years ago with a vision to provide exceptional environmental testing services and uphold environmental responsibility. Our beginnings are rooted in a passion for accuracy, reliability, and customer satisfaction, values that have guided our growth and development over the years.

As a result of the rebrand of the two finest labs in the Chicago area, EMT and STAT Analysis, Sterling Labs seeks to consistently expand its capabilities and expertise, embracing new technologies and methodologies. This has earned us a reputation for excellence, not only for our state-of-the-art testing services, but also for our unwavering commitment to our clients.

As we look back at our beginnings, we take pride in our achievements and the positive impact we have made. Our journey serves as a testament to our unwavering commitment to quality, sustainability, data defensibility, and customer satisfaction, which will continue to guide us as we move forward and shape the future of environmental testing.

Where we are

Our testing facilities are strategically located in the Chicagoland area, with a facility in the downtown loop and another in the suburbs, just minutes away from O’Hare International Airport. This means that not only are we conveniently located for sample pick up/drop off, but we can effectively address shipping concerns and accept samples seven days a week from UPS, FedEx, and Air Cargo firms. This ensures smooth operations for remote projects all over the country.

Everything we’re doing here is trying to increase our capacity, reduce the margin for error, and improve the quality of the lab.
