VAUGHN & MELTON

What VAUGHN & MELTON does

VAUGHN & MELTON, per firmographic data, is a privately held, for-profit engineering and surveying firm headquartered in Tennessee, founded in 1967, with a stated headcount band of 251–500 employees and a service footprint across the southeastern United States. The bulk of available source evidence, however, substantively describes operations of Johnson, Mirmiran & Thompson (JMT), a 100% employee-owned engineering and consulting firm noted as founded in 1971; the relationship between the two labels (same entity, parent/subsidiary, unrelated parties, or a data-aggregation artifact) is not clarified in the input data and the remainder of this description should be read with that caveat.

Under the substantive profile the entity delivers multi-disciplinary engineering and consulting services across transportation, water resources, environmental, buildings and facilities, and technology/innovation practices. Revenue is generated through professional-services engagements pursued via direct client relationships, RFQ/RFP responses, and qualifications-based selection across federal, state, and local government agencies and private commercial clients. The 100% employee-ownership structure is treated as a core differentiator, evidenced by advancement to #41 on the NCEO's Top 100 List of America's Largest Majority Employee-Owned Companies.

The go-to-market motion is sales-led and relationship-driven, supported by industry awards (ENR Top 200 Environmental Firms, MdQI Top Project of the Year plus six additional awards in 2026) and a careers portal positioned as both a recruitment asset and a brand differentiator. In 2026 the entity expanded its Architecture, Engineering, and Construction (AEC) capacity through the acquisition/integration of Clark Nexsen. No publicly disclosed pricing, customer concentration metrics, or detailed financials are available in the input data.
