What Marsh Wortham does

Marsh Wortham, doing business as Marsh McLennan Agency (MMA), is a U.S. insurance brokerage and risk advisory firm operating as a subsidiary of Marsh, itself a business of Marsh McLennan Companies (NYSE: MMC). Founded in 2018 in its current branded form, the firm is headquartered in Houston and reports a headcount above 10,000, positioning it as one of the larger middle-market brokerage platforms within the Marsh McLennan portfolio. Its offering is organized around four service lines — Business Insurance (property, casualty, cyber), Employee Health & Benefits (HR consulting, pharmacy benefits, HR technology consulting), Private Client Services (homeowners, auto, liability for high-net-worth individuals), and Retirement & Wealth (employer retirement plans, financial well-being, wealth management) — supplemented by featured solutions such as Business Interruption, Stop Loss, Workers' Health 360, Claims Management, and ERISA Consulting.

The firm serves enterprise and mid-market business clients across 26 industry verticals, including Agribusiness, Automotive, Aviation, Construction, Energy, Financial Institutions, Healthcare, Life Sciences, Manufacturing, Real Estate, Technology, and Transportation, alongside a high-net-worth individual book. Distribution is relationship-driven, executed by vertical and service-line specialists, and supported by content marketing, an events programme, and the LIMITLESS Magazine thought-leadership platform. Underlying technology leverages shared platforms across the Marsh McLennan enterprise, with emerging references to AI-driven decision support.

Revenue is generated primarily through insurance brokerage commissions and advisory fees, with pricing determined on a quote basis tied to client risk profile, coverage requirements, and market conditions, billed annually. The firm is part of an integrated risk, benefits, and wealth ecosystem that includes sibling Marsh McLennan businesses Mercer, Guy Carpenter, and Oliver Wyman, enabling cross-sell of health, reinsurance, and consulting capabilities that pure-play brokers cannot offer.
