Our Approach

We excel in our business because the services we provide are fast, reliable, and of the highest caliber. We don't merely run tests and send results--we provide customized solutions. Clients are drawn to us because we work with them as a thought partner, helping them think through their challenges and find solutions to their problems.

Our Story

After observing how states across the country were moving toward the legalization of medicinal and adult-use cannabis, the principals at Elbert Testing Labs recognized that there was an opportunity to apply their knowledge and experience from the pharma and biotech space to cannabis testing, in the state of New Jersey and across the country. What we do best is work with our customers to truly understand their work and their goals, so we can properly advise them, provide the services they need, and deliver timely, accurate results. We gain greatest satisfaction when our customers tell us how impressed they were with our work—and return to us the next time or refer new clients to us.
