What Sebago Technics does

Sebago Technics is a multi-disciplinary engineering and land development firm headquartered in South Portland, Maine, founded in 1981 by Walter P. Stinson, PE. The firm operates as a 100% employee-owned company through an ESOP trust (fully employee-owned since 2007) and employs 135 professionals across four Maine offices in South Portland, Bridgton, Sanford, and Brunswick following the November 2025 acquisition of Lincoln/Haney Engineering Associates.

The company delivers integrated professional services spanning eight core disciplines: civil engineering, surveying and geomatics, landscape architecture, transportation and traffic engineering, environmental services, planning and permitting, structural engineering, and CADD/3D modeling and graphics. Technical differentiators include the proprietary Aero-Geomatics® service combining UAV-based LiDAR and photogrammetry, high-definition 3D laser scanning deployed since 2013, centimeter-accurate coastal visualization for sea level rise modeling, and an in-house Traffic Management Center that performs daily operations of the Maine Mall Area signal system in South Portland and Scarborough. The firm also offers specialized capabilities in stormwater management for constrained sites and immersive 3D visualization for community engagement.

Sebago generates revenue through fee-based, project-specific professional services engagements priced by scope, complexity, and duration. The go-to-market is relationship-driven, combining enterprise direct sales with community-led engagement for municipal and state clients across Maine and New England. Primary customer segments include government and municipalities (roadway, traffic signal, parks, coastal resiliency), private developers (residential, commercial, industrial site development), educational institutions, and healthcare systems. Notable projects include the Sarah Mildred Long Bridge and I-91 Bridge Replacement (both ACEC National Grand Award winners), the Town of St. George Coastal Resiliency Project (2025 Climate Innovation Award), MaineHealth ambulatory surgery center, L.L.Bean corporate campus, and Aroostook State Park improvements. Revenue is not publicly disclosed; no funding rounds or external investors are present.
