ISCO Council member Josh Dubach (formerly CTEH)  tells us that as of April 22nd, CTEH has transitioned over to Onterris, who have issued the attached statement.

Montrose Environmental Group has become Onterris, a united global brand that reflects the company’s broader role in helping organizations solve complex environmental challenges with scientifc rigor, operational quality and practical execution.

The new name brings together Montrose Environmental and legacy subsidiaries including CTEH, ECT2, Enthalpy Analytical and Epic Environmental under one identity, creating a clearer and more consistent experience for clients and partners across regions and services. Onterris operates across the United States, Canada and Australia as a pure-play environmental solutions company.

The Onterris name combines “on,” symbolizing motion and intent, with “terris,” meaning earth. Inspired by NASA’s “pale blue dot” image of Earth, the brand reflects a shared responsibility to protect the planet while supporting responsible progress. The Onterris guiding principle is For Planet and Progress.

While the name is new, the mission remains unchanged: advancing the way of life without compromising the integrity of our environment. Onterris partners with organizations to address challenges where environmental pressures, regulatory expectations and operational risks intersect. Its scientists, engineers, field teams and consultants apply systems thinking, data, field expertise and scientifc insight to help clients strengthen resilience, reduce risk and protect the air, water and soil that sustain communities.
