Different names, same business

From the beginning, Mercer has been in the business of putting people's futures first. In 1945, William M. Mercer, Ltd began in Canada and grew to become a premier provider of actuarial and benefits consulting services. Acquired by Marsh & McLennan Companies in 1959 and merged with their own employee benefits department, the firm expanded through growth and acquisition to become a global leader in health, wealth and career.

Breaking down the business

Mercer organizes its business around three key areas: Health, Wealth and Career, each with distinct areas of practice.


Mercer is a leader in the health and benefits marketplace globally. The firm delivers trusted advisory services, brokerage and innovative solutions that help employers and their employees improve the quality, cost and experience of healthcare.

Mercer provides access to local market experts as well as national and international resources that advise on regulatory compliance and innovative strategies across health benefits, pharmacy, network providers and population health. Outside of North America, Mercer’s health business goes to market with its Marsh & McLennan Companies sister company, Marsh, as “Mercer Marsh Benefits”.  In 2017 Mercer concluded the acquisition of Thomsons Online Benefits which through its market leading Darwin platform provides benefits management solutions.
