Marsh 

Marsh McLennan, which now trades and brands in public as Marsh, is the professional-services group that still writes risk, strategy, and people as one holding-company sentence rather than a high-street insurance stall. On marshmclennan.com the firm presents Marsh Risk for insurance broking, Guy Carpenter for reinsurance and capital, Mercer for health, wealth, and talent, and Oliver Wyman for management consulting, with colleague and country figures the company prints for itself. The first sentence of the story remains Marsh McLennan even when the social handle reads Marsh. Those colleague counts, country lists, and brand maps belong on the corporate site and in filings; they are cited here only as the group’s own yardsticks, not as an independent census, and they are not insurance, investment, or consulting advice. The operating catalogue is advice and placement: how a client sees risk, how reinsurance sits behind it, how people and retirement plans are designed, and how strategy work from Oliver Wyman sits beside the brokers. Official X carries MarshGlobal under the Marsh name. It carries research notes, results colour, and thought-leadership films. It is not a policy desk, a claims inbox, or a place to share medical, payroll, or payment data. Clients are corporates, public entities, and institutions that need a risk-and-people partner that still picks up after the first catastrophe season. Commercial, media, and shareholder mail belong on the contact routes Marsh publishes, including marsh.investor.relations@marsh.com on investor pages. Follow the official MarshGlobal page for the operating group, then verify every brand name, country figure, and ticker claim at the source. The January 2026 brand move from Marsh McLennan to Marsh, and from MMC to MRSH, is the company’s own announcement; the legal structure and the four operating businesses remain the story the investor pages still tell. Marsh Risk places insurance, Guy Carpenter places reinsurance, Mercer works health and retirement and talent, Oliver Wyman sells strategy. Colleague counts above ninety-five thousand and country counts above one hundred thirty are Marsh’s figures. They are not a bid, a binder, or a pension recommendation. Official MarshGlobal on X is a research loudspeaker. It will not bind a line, quote a treaty, or take a census file of employees. Anyone treating a geopolitical essay as coverage advice should call the broker of record the client already appointed and read the slip.
