Mercer is a leading global professional services and management consulting firm specializing in the areas of talent, health, retirement, and investment solutions. Founded in 1945 by William Manson Mercer in Vancouver, Canada, the company originally began as an actuarial and employee benefits consultancy. In 1959, it was acquired by global professional services firm Marsh McLennan (NYSE: MMC) and integrated into its operations. Today, Mercer stands as one of Marsh McLennan’s four major operating subsidiaries, alongside Marsh, Guy Carpenter, and Oliver Wyman. The firm is headquartered in New York City and maintains a significant international footprint, employing over 25,000 professionals across more than 40 countries and operating in upwards of 130 countries worldwide. The core operations of Mercer are broadly categorized into three major business pillars: Health, Wealth, and Career. Through these segments, the firm delivers advice and technology-driven solutions tailored to help organizations navigate the evolving health, retirement, and workforce needs of their employees. In the Health vertical, Mercer assists employers in designing, managing, and optimizing healthcare and employee benefit programs. This includes advising on medical insurance plans, wellness strategies, benefits administration solutions, and vendor management to enhance employee well-being while optimizing corporate spending. The Wealth segment encompasses Mercer's retirement and investment consulting practices, which were consolidated into a unified division in 2017 to provide highly integrated solutions. Mercer serves as a massive institutional asset manager and advisor, recognized globally as the world's largest outsourced chief investment officer (OCIO) provider. The firm has more than $300 billion in outsourced assets under management and multi-trillion dollar figures under advisement globally. It guides clients through pension plan transformations, defined benefit schemes, and broad investment strategies. In the Career vertical, Mercer offers strategic counsel on workforce and talent strategies. This involves advising on executive compensation, remote work policies, global mobility programs, employee engagement, and diversity, equity, and inclusion (DEI) initiatives. Additionally, Mercer’s M&A advisory team provides critical support during corporate mergers and acquisitions, ensuring the seamless integration of pay structures, corporate cultures, and benefit programs. Led by President and CEO Pat Tomlinson, Mercer has continually expanded its capabilities through strategic acquisitions—such as buying the digital HR consultancy Leapgen in 2023 and agreeing to acquire SECOR Asset Management in 2025. By embedding modern technology, such as AI-based pension decision tools and financial wellness hubs like Mercer Money, the firm continues to advance the performance, health, and wealth of the global workforce.
