About Us

A Brief History...


John Maltby, President and CEO  


Since our inception over 50 years ago, Maltby Electric Supply has prided itself on delivering the highest quality and best value to our customers. This philosophy has helped us grow into a regional industry leader, distributing a wide range of electrical products throughout Northern California.

As our many satisfied customers have come to know, Maltby Electric Supply offers not only products and services on which you can depend but also a convenient, cost-effective partnership that will help your business succeed.

Maltby Electric Supply is a leading supplier of electrical products to the Northern California market. With a half-century of experience, Maltby Electric Supply sets the market standard from San Francisco to Ukiah and Sacramento to San Jose. Our customers — commercial, residential and industrial contractors, hospitals, schools, governments, airports, public works, industry and more — have come to rely on us for quality products, competitive prices and superior service.

After celebrating our semi-centennial, we're proud of how far we've come. By meeting customer needs, innovating with the industry and understanding the local market, we have grown from a small family business into a major Northern California player.

In 1955, brothers Jack and Chart Maltby began a business with just four employees. Growing steadily, Maltby Electric Supply was incorporated in 1961. Soon thriving, Maltby Electric Supply expanded into Sonoma and Marin, opening a Petaluma store and establishing a headquarters in San Francisco in 1980, a San Rafael branch in 1988 and a fourth branch in Fairfield to serve Solano County in 1994. When Chart Maltby passed away in 1978, his brother continued as president until his retirement in 1993. Jack's daughter Susan took the helm at Jack's retirement, and was replaced by Jack's son John in 2003. John Maltby continues the tradition of excellence that brought the company this far, and, with the support of his committed employees and dedicated customers, he looks forward to another 50 years of success.
