Who is Liberty Dirtwork LLC
Our Team
Lee and Heather Cook
Lee and Heather Cook founded Liberty Dirtwork in 2015, building it on the values of faith, family, and hard work. What began as a small operation has grown into a trusted name across North Dakota, thanks to their dedication to quality, perseverance, and determination. Today, they're proud to have the entire family involved-continuing the work together, just the way it started.
Isaiah Cook
Isaiah, son of founders Lee and Heather, is a partner in the business and an essential part of Liberty's day-to-day operations. With a strong work ethic and a passion for the trade, he continues to help carry the family vision forward.
Terry Thiel, Christopher Mosbrucker, Hannah Mosbrucker, Sarah Cook, and Daniel Morehouse
Behind every machine and every jobsite is a crew that carries on the Liberty legacy. We are more than coworkers-we are a team built on hard work, honesty, and commitment to progress. Theses are the names and faces you'll see driving the work, and the results, day after day.
Gus
Gus is the family/company dog. He's also the brains of the entire operation.
Meet Leonard-Carrying four
generations of pride.
Leonard isn't just the name we gave a dozer, it's the name of of four generations of men in our family-men who believed in honest work, looking a neighbor in the eye, and keeping your word.
From the first Leonard who worked the Washington mountain land with little more than a shovel and a strong back, to the the next who learned to run the early machines, to the one who taught us that faith and family come before everything by taking a leap of faith and carving his name in The North Dakota ground, and the one who is helping to continue building a legacy. Each leaving their mark, and now their name lives on-breaking new ground, building roads, and helping other families lay their own foundations.
Every project we take on is a page in their story. Early mornings, long days under the North Dakota sun, and the satisfaction of knowing the job is done right-just like the Leonard's before us would have wanted.
When you see Leonard out on a job site, you're not just seeing a dozer at work. You're seeing a promise-one built over decades, handed down like a well-worn set of tools, and kept alive with every cut, grade, and load of gravel. Because at Liberty Dirtwork, this isn't just a business. It's our family story. And we're honored to make it part of yours.
