About Marsh
Marsh and McLennan was founded by Henry W. Marsh and Donald R. McLennan in 1905. It made its first acquisition in 1923 with the reinsurance firm Guy Carpenter & Company, and a series of key acquisitions followed, allowing Marsh and McLennan to reorganize itself as a holding company. In the late 1990s, Marsh and McLennan acquired Johnson & Higgins, making it the world’s largest insurance broker at the time. Marsh and McLennan’s corporate headquarters is located in New York City.
Marsh and McLennan offers numerous products and services, including brokering, risk management, investment management, and retirement funds. Prospective employees can search for career opportunities within each of Marsh and McLennan’s businesses: Marsh, Guy Carpenter, Mercer, and Oliver Wyman. Oliver Wyman offers entry-level consultant roles, as well as NERA internships for students and recent graduates.
Marsh and McLennan is committed to diversity and inclusion in the workplace. It is part of the Stonewall Diversity Champions program and signed up with the Stonewall Workplace Equity Index, a tool for businesses to measure their progress on LGBTQ+ inclusion in the workplace. Marsh and McLennan encourages its employees to volunteer in their communities by offering incentives such as paid time off and matching employees’ charitable contributions.
