Our Philosophy
At CMEC, environmental compliance is more than a regulatory requirement. It is a vital part of responsible development. When done right, it protects health, preserves the environment, and strengthens communities.
We identify potential issues early, offer practical solutions rooted in regulatory expertise, and keep projects moving without costly risk or delay. Clients trust us for sharp insight, clear communication, and real accountability from start to finish.
We stay lean and agile so you get the right attention without layers of bureaucracy. Our work is grounded in both the technical precision of a national firm and the hands-on commitment of a trusted local partner.
For us, compliance is about safe housing, healthy environments, and stronger communities. We partner with agencies, developers, and stakeholders to make sure projects meet regulations while supporting long-term community goals.

Meet the real boss
Overseeing team morale, office security, and treat distribution

Stella Curtis - Chief Barketing Officer
She makes sure no delivery person goes unannounced. Morale stays high thanks to tail wags and soulful (sometimes judgy) stares, and she’s the team’s most loyal teammate, even if she occasionally sleeps through meetings. Stella doesn’t know much about compliance, but she’s an expert in snacks.
