FAMILY

As a family with many members, we have each other’s backs.

Spread from coast to coast, we’re all about expanding our expertise, supporting each other through our diverse offerings and capabilities. Because when one of us succeeds, we all succeed — and we can only be at our best when we work together. General contractor, mechanical contractor, service, and building automation … that’s one powerful construction family.

Five brands.

Made up of five brands with offices across the country, MMC Corp is a 100 percent employee-owned company dedicated to the success of our partners and teammates.

Fourteen offices.

Located in 14 offices from California to New Jersey, our expertise spans many regions and industries, equipping us to serve clients throughout the entire construction process.

One family.

Though spread out at offices and project sites nationwide, one thing remains — we are a family, a unified team that is better as a whole than individually. At the core, we are builders, we are teammates — and we are all in it together.
