About Longo

Since 1945, Longo has provided Service Through Knowledge to customers throughout the Northeast…

John Rocco Longo founded Longo in his basement in Morristown, New Jersey. From this humble beginning, Longo has grown into the largest independent, family-owned electrical-mechanical business in the Northeast!

As a family business, Longo is driven by the value of quality workmanship and providing unmatched electrical-mechanical expertise for customers across the United States, and as far away as Japan and South America! Longo’s associates combine a depth of experience with unrivaled effort to maintain proficiency in the latest techniques, equipment, technology, and materials. As the industry leader, Longo is built on a foundation of hard work, high quality, reinvestment, and learning with our customers that underlies the company’s dedication to performance and reliability.

Longo was the first electrical-mechanical business in America to be certified by ISO-9001, and is a member of the Electrical Apparatus Service Association. The company has over 100,000 sq. ft. of plants spread across its four locations – Wharton (NJ), Linden (NJ), New York City, and Philadelphia.

In 1921, John Longo arrived in America from Italy with little more than a fourth grade education and determination to find a better life. Eventually making his way to Morristown, New Jersey, John enrolled in “English for Immigrants” at the local Neighborhood House. Despite his limited formal education, John demonstrated an aptitude for mechanical skills and was recognized as a reliable local handyman.

1945

In 1945, John founded J.R. Longo & Sons in his basement in Morristown. Early customers included other local businesses including Morris County’s local newspaper, the Daily Record, which hired Longo to rewire their entire newspaper production plant!
