Built so one call gets you
the right team, anywhere.
Large firms got too big to be responsive. Small shops stayed too small to be comprehensive. CE3 was built in between — senior-level expertise, global reach, and the agility to actually pick up the phone.
Community. Environment. Ecology. Economy.
CE3 Group was founded on a conviction that environmental consulting is broken — or at least badly fragmented. Too many firms silo compliance from ecology, ecology from economics, and economics from the communities that live with the consequences.
CE3 stands for the four forces we believe every environmental engagement must balance: Community, Environment, Ecology, and Economy. It's not a tagline. It's a design principle. Every team we assemble, every strategy we design, and every recommendation we deliver is evaluated against all four.
The result is an approach that's genuinely integrated — not a collection of specialists working in parallel, but a single team thinking across disciplines from day one. We serve as prime contractor, strategic partner, specialized subcontractor, technical advisor, or global project coordinator — whatever role your project needs us to fill.
We've sat on every side of the table.
Our principals have been the regulator writing the enforcement action, the plant manager receiving it, and the consultant called in to fix it. That range of perspective — regulatory, industrial, and consulting — is what sets CE3 apart. And unlike larger firms, our senior leaders stay on your project from kickoff through closeout.
Clay Hinkle, BA, MBA
Principal & Founder
Clay founded CE3 Group because he'd spent three decades watching environmental programs get fragmented across too many firms, too many handoffs, and too many missed connections between disciplines. His career arc is unusual in the industry — and it's exactly what makes CE3 different. Clay progressed from regulatory agency specialist to aerospace EH&S manager to environmental consultant, building a comprehensive understanding of environmental challenges from every stakeholder's perspective: the regulator's, the operator's, and the consultant's. With 30+ years leading environmental programs for government agencies, Fortune 500 companies, and international development organizations across the U.S., Canada, and the Middle East, Clay built CE3 around a simple premise: the best environmental consulting happens when compliance, ecology, and economics are in the same room from day one.
