Our Values Lead the Way

Driven by our four core values of quality craftsmanship, entrepreneurial spirit, teamwork, and integrity, our employee owners carry out our vision of continued innovation and growth to better serve new and existing clients.



Integrity is our cornerstone. By conducting our business according to the highest standards of integrity and ethical behavior, we always tell the truth, keep our promises, and hold ourselves accountable for every decision we make.

We embrace teamwork while respecting the individual. Our foundation of teamwork and collaboration allows us to build sustainable relationships with our fellow employees, our clients, our business partners, and our communities.

We believe in the power of our entrepreneurial spirit. Our success comes from having the imagination to visualize what is possible, the courage to try new things, and the resourcefulness to always find a way to get it done.

We take pride in our craft, ensuring quality, safety, and value on every job. It’s critical that every aspect of our work reflects the highest level of quality, safety, craftsmanship, and professionalism.

Our Way

Since our founding more than 85 years ago, we've learned a thing or two about mechanical contracting. You can talk all you want about success, but at the end of the day, success in our business is measured by results. And we believe real results begin with real values.

At MMC Contractors, integrity and accountability lead the way. As a company and as individuals, we value teamwork, entrepreneurial spirit, quality craftsmanship, and integrity above all.

Each day, across our offices, in our fabrication shops, and on our job sites throughout the country, we hold ourselves accountable — to each other and to our clients. That's our foundation — the values that define everything we do.

Over the years, we've been consistently ranked as one of the "Top 25" specialty contractors in the United States. We're proud of those results. And we're just as proud of our values that continue to lead the way. You can see our values come to life by viewing our portfolio.

Employee Ownership

As an employee-owned company, our success is a collective effort. We are all owners, pulling together toward a common goal, united by a mutual stake and interest in our company's success and, most important, the satisfaction our clients.

Our Services

We specialize in large, complex mechanical systems, with a comprehensive offering of preconstruction, construction, and service offerings. We work in some of the nation's most challenging markets, including healthcare, energy, pharmaceutical, and industrial and commercial markets.

Our Story

Discover opportunity in challenges. That's what our founder, Claude Sanders, did in 1932 when he lost his job like a lot of other folks during the Great Depression. Claude turned his sights on starting a residential plumbing service company, which he called Midwest Plumbing and Heating Company. He worked out of his house as he slowly built his business with few resources and an entrepreneurial passion.

Through the years, we've relied on his vision and determined spirit. And now, more than 85 years later, our seven locations — Des Moines, IA; Kansas City, MO; Las Vegas, NV; Omaha, NE; Nashville, TN; and Somerset and Swedesboro, NJ; — have come together as a single, united brand called MMC Contractors.

As MMC Contractors, we offer our partners better, more seamless collaboration across our companies and between our job sites nationwide. We offer the best of both worlds — the feel of the local company next door paired with the wide presence, perspective, resources, and expertise of a national brand.

We are committed to continuing Claude's entrepreneurial legacy. Together as MMC Contractors, we will build toward a strong future for our company and our clients.
