SEH

SEH, or Short Elliott Hendrickson Inc., is an engineering, architecture, planning and science firm that is 100% employee-owned. It delivers complex infrastructure projects across the United States, combining local knowledge with a national network. Its technical work spans civil engineering, water and clean-water infrastructure, transportation and mobility, environmental science, and infrastructure renewal.

The firm's services are organised around three broad capabilities. Engineering covers complex infrastructure challenges, including mobility improvements and clean-water projects. Architecture and planning cover the design of buildings and places, and the renewal of existing infrastructure, as part of multidisciplinary project teams. Science and environmental services apply scientific expertise alongside engineers, architects and planners, working as invested collaborators with clients rather than as outside consultants. The firm's stated mission is Building a Better World for All of Us®.

Employee ownership is central to how SEH describes itself: every team member holds a personal stake in the collective result. The firm reports a culture in which employee-owners support one another, mentor the next generation of professionals, and work with a degree of autonomy and flexibility that allows them to balance work and personal life. An entrepreneurial and collaborative mindset is cited as a defining feature of the workplace.
