How Murphy Started

In 1882, John C. Murphy traveled to St. Louis, Missouri, with the intent of creating a better life. The Irish lad came to learn the plumbing trade and in 1907, confident in his mastery, formed John C. Murphy Plumbing Co. Little could he have imagined that he was launching a firm destined to become the largest mechanical contractor in St. Louis, opening an office in Denver in 1983, and becoming the 17th largest in the United States. Nor could he have envisioned the decades to follow that his enterprise would make a better life possible for thousands of customers and employees.

From our origins as a two-man plumbing shop to today, Murphy Company employs over 300 salaried workers and 1,000 union craft workers in the pipefitter, boilermaker, plumber, sheet metal, HVAC, and laborer trades from its headquarters in St. Louis and regional offices in Colorado.

Murphy Today

Patrick J. Murphy, Jr., John’s great-grandson, is the fourth member of the close-knit Murphy clan to become president of the company, succeeding his cousin James J. Murphy, Jr., in 2005. While our record of success is impressive, it’s the people who count the most. We support our employees throughout our company, ensuring they have the tools, training, and technology to make them successful. We continuously recruit top talent within our industry and invest in their ongoing skill development. Our employee’s health, safety, and well-being remain our top priority. We want each employee to return safely to their family each day so we insist on maintaining safe work sites for all our employees and customers.

Since our founding more than a century ago, Murphy Company has built a proud legacy of excellence that is alive and well today. Much of our business is built on repeat customers who partner with us year-after-year because of the high level of customer service and expertise that are synonymous with the Murphy name.
