What Wiles Mensch does

Wiles Mensch Corporation - DC is a multi-disciplinary site development consulting firm headquartered in Washington, D.C. with a secondary office in Reston, Virginia. Founded in 1988, the firm operates a 51-100 person practice delivering four integrated service lines: civil engineering, land surveying, dry utility design, and landscape architecture. The firm specializes in projects requiring complex permitting across DC and Virginia jurisdictions, sustainable site design, and stormwater management, with demonstrated LEED expertise across all certification levels. Notable engagements include the US Census Bureau Headquarters, the National Mall turf restoration, the GWU Science & Engineering Hall, the DCPL Southwest Library, and the Blue Plains Tunnel.

The firm generates revenue through project-based professional services fees, pursuing work via direct client engagement with government agencies, institutional clients, and private developers, as well as in the role of subconsultant to architecture firms on design-bid-build and design-build teams. Target segments span federal, district, and local government (a primary segment), private developers (primary), educational institutions, and healthcare providers. Pricing is project-specific with no public rate cards. The firm holds SBA, CBE, and MWAA LDBE certifications that support access to set-aside public contracts. Distribution is entirely direct and regional; the firm operates no public API, no digital sales channel, and no resellers.

Wiles Mensch completed a corporate rebrand in 2021 alongside a leadership transition in which founder Joe Mensch (34 years) and Mary Ramsey (32 years) moved to adjunct roles, passing operational leadership to a tenured principal group (Marcelo Lopez, William Lattanzio, Craig Atkins, Gavin Clarke). The firm has accumulated 2,000+ completed projects over its 34-year history and continues to actively win awards (most recently 2025 GALA Community of the Year for District Towns at St. Elizabeths East), reflecting a stable, regionally entrenched professional services practice.
