Simmons & White

What Simmons & White does

Simmons & White, Inc. is a privately held professional engineering firm founded in 1982 and headquartered in West Palm Beach, Florida, with a second office opened in North Charleston, South Carolina in 2024. The firm provides civil engineering and land development, traffic engineering and transportation planning, and due diligence and entitlement services to both public and private sector clients across the Southeastern United States, including residential developers (multifamily, single-family, life-planned communities), commercial office/retail, healthcare facilities, educational institutions, equestrian and polo properties, industrial and distribution centers, golf courses, and municipal governments.

The firm's technical work centers on conventional civil engineering design using Autodesk Civil 3D software for site development, utility and roadway design, master planning, construction plan preparation, FEMA flood plain management (CLOMR/LOMR filings), and traffic studies including signalization, intersection improvements, and DRI analysis. Services are delivered directly by the firm's professional engineers and project managers without intermediary channels, supported by an in-house AutoCAD team and a roster of P.E.-licensed staff across civil and traffic disciplines.

Revenue is generated through fee-for-service professional engineering engagements with both developers and municipalities; pricing is quote-based and not publicly disclosed. Customer acquisition is driven by long-tenured client relationships (several spanning 25+ years), client referrals, professional association participation, and a Citadel School of Engineering talent pipeline. The firm is independently owned by its executive team with no disclosed private equity, venture capital, or parent company ownership.
