The Goal

Our Mission

DS Environmental exists to give property owners, contractors, and public agencies clear answers when it matters most. From a pre-demolition survey on an 800,000-square-foot commercial site to a mold assessment ahead of a home sale, our job is the same: deliver accurate testing, honest reporting, and practical guidance — on schedule and without surprises. We work across commercial, residential, institutional, and government projects because good environmental practice shouldn’t depend on the size of the job.

The Outlook

Our Vision

We want to be the environmental partner Colorado turns to before a shovel ever hits the ground or a hammer hits a wall. The firm whose assessment is trusted by contractors, regulators, and property owners alike. As our communities grow, redevelop, and rebuild, we’re working toward a standard where environmental due diligence is routine, not an afterthought, and where every project we touch is safer for the people who build it, use it, and live near it. We strive to evoke trust, dependency, and commitment with every client, whether a one time project or a life-long partnership.
