Our history
From the beginning, we’ve put 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 in 1959 and merged with its own employee benefits department, the firm expanded through growth and acquisition to become a global leader in health, retirement, investments and talent.
Even as times have changed and our firm has evolved, our core purpose has remained clear: We make a difference in people’s lives. For generations, we have provided clients with actionable insights and forward-thinking solutions, and as our global reach and resources have expanded, so have our capabilities. Today, Mercer works with clients in 130 markets around the world, helping them continue to make the future brighter for their employees.
