What Thompson & Litton does
Thompson & Litton, Inc. is a 100% employee-owned, full-service architectural, engineering, and surveying firm headquartered in Wise, Virginia, founded in 1956. The company delivers multi-disciplinary professional services spanning architecture, civil, structural, mechanical, electrical, and plumbing engineering, transportation planning and design, land surveying, construction contract administration, and Designer-Led Design-Build project delivery. It serves towns, cities, counties, school boards, public service authorities, higher education institutions, and private industrial and commercial clients primarily across Virginia, West Virginia, and Tennessee, operating from eight regional offices (Wise, Radford, Tazewell, and Chilhowie, VA; Bristol, Johnson City, and Mosheim, TN; and Princeton, WV) following the May 2024 acquisition of Tysinger, Hampton & Partners.
The firm executes work through a project-based professional services model, acquiring engagements via competitive public-sector bidding, direct client engagement, and design-build delivery. Its core technology stack comprises industry-standard AEC tools — AutoCAD MEP, REVIT, ETAP, Visual 2012, SpecLink, and Power Tools for electrical modeling — and it maintains in-house capabilities across all major engineering disciplines. T&L holds no disclosed patents or proprietary technology assets and shows no AI/ML or software-product revenue.
Revenue is generated through two streams: comprehensive engineering, architectural, and surveying services, and design-build/design-assist project delivery (including Designer-Led Design-Build and Construction Manager at Risk). Pricing is project-based and not publicly disclosed. The firm employs over 150 professionals and support personnel, with senior tenures commonly exceeding 25-30 years. Notable engagements include the $37.1M UVA-Wise Library, a $14.7M Virginia Department of Corrections security upgrade, a $9M New River Resource Authority landfill project, a $3.4M Radford City Public Schools classroom addition, and a $93M (20-year) Lonesome Pine Regional Business and Technology Park development. The company is led by President Greg Hurst, with recent leadership transitions in 2023-2025 strengthening the Client Service function.
