Our Clients

We are proud to have crafted enduring relationships by remaining responsive to our customers’ unique needs. Many of our earliest customers still depend on us for the unparalleled support they have grown accustomed to from Patterson & Dewar.

Patterson & Dewar began by providing civil and electrical engineering and land surveying services in 1947 for rural electrification programs that were extending service to towns and farms in the Southeast. Today, we offer a wide range of services to electrical cooperatives, municipalities, investor-owned utilities, industrial companies, transportation providers, state and local governments, and residential & commercial developers.

Our wholly-owned subsidiary, Hood-Patterson & Dewar (HPD), is a leading provider of electrical and mechanical testing and commissioning services in major computer centers across the country and around the world. HPD has commissioned hundreds of data centers and has served as an independent third-party commissioning agent for owners, engineering firms, construction managers, and electrical subcontractors in a wide range of environments.
