McCarthy

Since its origins in 1864, McCarthy Building Companies’ journey embodies the enduring power of family values, innovation, and unwavering commitment to excellence. 

Founded by Irish immigrant Timothy McCarthy, this remarkable company evolved from building farmhouses and barns to constructing some of the nation’s most complex projects—from cutting-edge hospitals and research facilities to massive solar installations and iconic stadiums. Through economic depressions, world wars, and industry transformations, McCarthy has remained guided by a simple philosophy: “We have always done the very best possible work on every contract we got.” 

The company’s most transformative moment came in 2002, when Mike McCarthy, the last family owner, sold his shares to the employees, creating a 100 percent employee-owned company. This bold decision catalyzed a cultural shift from internal competition to collaboration, propelling McCarthy to new heights while preserving its family-oriented culture. 

Today, McCarthy’s story represents more than construction history—it exemplifies how core values of being “Genuine,” embracing “We, Not I,” and being “All In” create sustainable success. From the Priory Chapel’s architectural challenges, to pioneering renewable energy projects, from healthcare facilities serving communities, to resilient infrastructure withstanding nature’s fury, McCarthy continues its mission to be “the best builder in America.” 

This compelling narrative celebrates the builders, dreamers, and employee-owners who transformed a modest family business into an industry leader, proving that when people own their future, extraordinary things happen.
