CES, Inc. was founded in 1978 by Shawn Small, P.E. and Jim Parker, P.E. Shawn and Jim were classmates at the University of Maine and worked together at a local engineering and surveying company. Initially, the two worked from their homes but soon moved to an office building to make room for their growing staff.

During the 1980s, the company outgrew two office buildings in Brewer, Maine. By 1987, a building located on South Main Street in Brewer (formerly owned by the Archdiocese and serving as an office and an elementary school) was renovated as a new office building. Today, that building still serves as CES’ headquarters.

Business first focused on sanitary sewer design—Shawn developed solid and waste management services, and Jim led the way in land development services. Their philosophy for growth was to hire good people, find out what they like to do, and build business from their expertise.

Their commitment from the start was to provide clients with high quality, cost-effective technical services. Today, that commitment remains the same.
