What C White Marine does
C. White Marine, Inc. is a family-owned marine construction and pile driving contractor founded in 1994 by Larry and Cathy White and headquartered in Danvers, Massachusetts, with a secondary operations yard in East Boston. The firm operates four integrated service lines: marine construction (timber, steel, and concrete piers, docks, bulkheads, seawalls, floating dock systems, fender and mooring systems, cofferdams, and demolition); pile driving and foundation services (timber, pipe, and H-piles, lagging, soldier piles, shoring, and sheet piling for both marine and land-based applications); commercial diving (underwater inspections, anode installation, underwater burning and welding, scour protection, and pile jacketing); and small bridge construction and rehabilitation (causeways, timber and precast concrete bridges). Field operations are supported by owned marine construction plants, dive barge units, land-based pile driving equipment, cranes, and barges.
The firm serves a mix of public-sector clients (Town of Chilmark, Massachusetts Department of Conservation, MassDOT, MBTA, U.S. Navy, U.S. Coast Guard) and private-sector clients (Related Lovejoy Residential, MCRT/Modera Medford, Cole Parkway Marina, private marinas and yacht clubs, commercial marine terminals, and general contractors in New England). Subcontract pile driving for leading regional general contractors is a meaningful horizontal channel. Service delivery is project-based with quote-driven pricing (estimates routed through a dedicated estimating inbox), field-sales driven engagement, and revenue recognized on completed project contracts across Eastern Massachusetts, New Hampshire, Maine, and Rhode Island. The company is privately held by the White family, with son Dan White serving as Vice President; no external institutional capital, funding rounds, or M&A activity is recorded.
