Full company description
Headquartered in Walnut Creek, Calif., Brown and Caldwell is an employee-owned firm with 2,100+ professionals serving clients locally and globally from 52 locations. We are the largest engineering and construction firm solely focused on the U.S. water and environmental sectors.
Our creative designs and progressive solutions have helped municipal, federal and private organizations overcome their most complex environmental challenges. We offer a comprehensive range of engineering, scientific, consulting and construction services and all the essential ingredients® for a successful project and a standout experience.
We are passionate about delivering exceptional service, collaborating with clients, adding value through innovation and building relationships that last. This passion dates back to Ken Brown and Dave Caldwell, who, since founding the company in 1947, stood out for their ability to solve engineering challenges, apply technology to emerging environmental problems, and serve their community.
Service, great technical solutions, innovation. These are the qualities our founders carried forward as the world changed and the company grew into what it is today. Now, more than 75 years later, these qualities are just as important – essential, really – to Brown and Caldwell and to our clients.
