Midwest Mole has been a family-owned and oriented company from the beginning. Len Liotti started the business in 1982 after earning over a decade of tunneling experience. Rather than staying with his employer ― who was relocating from Indiana to St. Louis ― he decided to start his own tunneling business, with help from his wife and a business partner.

In the beginning, Midwest Mole focused on smaller tunneling projects across the Midwest. The company steadily grew as Len’s son, Dan ― who owns the business now ― joined the company and worked his way through the ranks.

The father-son duo took extraordinary care to grow meaningful relationships with not only equipment manufacturers, but also with other tunneling companies around the US. Thanks to their genuine friendships around the industry, more and more tunneling opportunities appeared on both coasts and everywhere in between.

Midwest Mole capitalized on the new opportunities thanks to our decades of industry experience, unique capabilities, and relentless problem-solving. We’re proud to have a talented field team, along with the dedicated and experienced fabricators in our shop, and the transport drivers who mobilize our equipment anywhere.

Why do we keep coming into work, even when the odds are stacked against us? The world of tunneling is unique and challenging. The ground conditions are king, and we never know what we’re going to encounter on each project we build. Some projects are flawless, while others require every year of experience our team members have. The challenge and excitement from our business is hard to find elsewhere. In short, we love what we do.

Today, we have projects not only all over the Midwest, but also east to D.C., and west to Arizona. We tunnel under railroads, highways, buildings, and even airports. While Dan ― and our company president Jason Miller ― provide extraordinary leadership, we’d be nowhere without our dedicated and hard-working teams. With such a strong family and company history, we plan to proudly tunnel anywhere our expertise and capabilities fit for decades to come.
