about us

A Different Approach

In the basement of a small-town home,
a big idea was born.

In 1973, two visionary engineers saw engineering as more than just problem-solving. They understood the power of relationships and set out to build meaningful local connections, shaping a future where people came first.
Today, we are adynamic, multi-disciplinary firm with 14 offices across five states, serving clients nationwide. While our team has grown and our reach has expanded, our commitment remains unchanged—we continue to prioritize the client experience in every decision we make.
Our MISSION

We exist to make a difference.

Challenge Excites Us

Some are intimidated by challenges. Not us. We don’t shy away from challenges or complex concepts—we’ve built our business on them. We meet challenges by matching the right people with each project based on their local knowledge, expertise, and experience.

Big ideas don't scare us. They inspire us.

Featured Work

No matter the project or the challenge, we're here for it. Our relationships with our clients are a testament to the success of the projects we have designed with them. Take a look!

It's no accident

Being owned by 100% of our employees is by design. Employee ownership fosters a culture of collaboration, investment, and commitment. Not everyone gets to carry an ISG business card, but those that do, own it!
