What Dewberry does
Dewberry is a privately held, family-owned professional services firm founded in 1956 and headquartered in Fairfax, Virginia, operating across 50+ U.S. locations with a workforce of 2,500+ employees. The firm delivers architecture, engineering, environmental, construction, geospatial, planning/consulting, and technology services to federal, state, local, and private sector clients across markets including transportation, water, energy, federal, justice, healthcare, education, telecommunications, and community facilities. Subsidiaries include Dewberry Engineers Inc., Dewberry Architects Inc., Dewberry Design-Builders Inc., and Dewberry & Davis Inc., and the firm holds ISO 9001:2015 and NSF/ANSI 391.1 certifications supporting its government contract base.
Dewberry generated $763 million in revenue in 2025 and ranks #35 on the ENR Top 500 Design Firms list, with a Transportation practice alone tracking $25 billion+ in construction value and $1.5 billion in associated revenue. Notable engagements include the NYCHA Clinton Houses stormwater program, the Big Bend Road design-build with Skanska, the James River Crossing, and the 7.2 MW Port Newark Solar project. Revenue mechanics are project-based, delivered under negotiated professional service agreements with public agencies and private developers, with a mix of design, program management, environmental, and construction-phase services.
The firm's business model centers on fee-for-service delivery across multi-disciplinary practices, supplemented by opportunistic acquisitions (most recently Edmonds Engineering in 2021) and a structured buildout of integrated design-build delivery through Dewberry Design-Builders Inc. Barry Dewberry serves as Executive Chairman, Donald E. Stone Jr. transitioned the CEO role to David J. Mahoney effective April 1, 2026, and Robert Williams was appointed President of the National Design-Build Practice on June 8, 2026, signaling an intentional shift toward higher-value, integrated delivery.
