Making the world a better place, one project at a time
Colman Engineering was founded in 2010 on a simple conviction: that engineering, done well, makes the world a little better. We're rooted in the Shenandoah Valley and western Virginia, but you'll find our work all across the Commonwealth.
About Us
Our Purpose
Engineering for a Better World
As engineers, we are committed to the advancement and betterment of public health, safety, and welfare. And that's exactly what we've been doing at Colman Engineering since 2010: Applying our engineering expertise to make the world a better place, one project at a time.
Our Values
Doing What's R.I.G.H.T.
What sets us apart isn't just technical skill; it's the values that shape how we work. Our values aren’t declarations of perfection—they’re guideposts for how we aim to show up every day, as individuals and as a team.

Respect
We aim to extend kindness, knowing that most of the time, everyone has the best intent.

Integrity
We value honesty and treating others as we ourselves want to be treated.

Growth
We continually look for ways to do what we do, better.

Holistic Thinking
We look beyond the task at hand, considering how decisions may impact the site in the future, neighboring sites, and the larger environment.

Timely Communication
We value responding promptly and reaching out proactively, to keep projects moving forward.
