Our Mission & Values
We improve the lives of our community, our partners, and our family by going beneath the surface to build America’s essential infrastructure.
Our success doesn’t rest on one individual — it relies on the entire MWM family at home and in the field working together towards a common goal. We believe in putting the needs of others before ourselves because we know when you take care of family, the family takes care of you.
We know the only way to function as a field-first company is through the individual actions of our entire team. Everyone, from office to shop, keeps our moles digging. We treat every person and task with the high level of respect expected throughout MWM.
Safety is a way of life, not a box we check. Through some hard lessons, we’ve learned that there are no shortcuts to the safety of our people. Safety is a daily habit at MWM that will always come before production.
We define a win as something that improves the lives of our partners, our community, and our family—and we love to win. We believe everyone, including our competitors, has the potential to create a win, which is why we build all relationships on trust, respect, and honesty.
We take every opportunity to solve problems and find efficient solutions. We also know that sometimes it just takes working harder than the rest. We’ll keep getting our hands dirty until the job is done right.
Do what’s right, especially when no one’s watching. You know what’s right and wrong. When you do the wrong thing, you not only hurt yourself but the entire family.
When work gets tough, and it will, we must persevere and push onward. There’s a solution to every problem, even if we must first step back to move forward and find our way through it.
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.
