Liberty Mutual Insurance, a prominent player in the property and casualty (P&C) insurance sector, has recently named Timothy Sweeney as the chairman of Liberty Mutual Holding Company. This significant transition took place on April 9, 2025, marking a new chapter for both Sweeney and the company.

Sweeney, who has been serving as the president and CEO since January 2023, steps into the role of chairman following the retirement of David Long. Long has had a remarkable career at Liberty Mutual that spans four decades, making his retirement a noteworthy event for the organization.

In his statement, Sweeney praised Long's leadership, saying, David's tenure has been defined by his unwavering commitment to excellence and the well-being of our employees. His leadership has transformed challenges into opportunities, ensuring that our core values remain at the center of everything we do. Sweeney's acknowledgment of Longs contributions underlines the legacy left behind by the outgoing chairman, who has played a pivotal role in shaping the companys direction.

David Long joined Liberty Mutual in 1983 and has held various leadership positions over the years. He became president in 2010, took on the role of CEO in 2011, and assumed the position of chairman in 2013. His extensive experience and strategic vision have been instrumental in navigating the company through the complexities of the insurance market.

Founded in 1912 and headquartered in Boston, Liberty Mutual has grown to become the ninth-largest global P&C insurer, based on gross written premiums projected for 2024. As of December 31, 2024, the company reported a staggering $50.2 billion in annual consolidated revenue. With over 40,000 employees operating across 29 countries, Liberty Mutual has established itself as a powerhouse in the insurance industry.

The company offers a diverse range of insurance products and services, catering to both commercial and personal lines. This includes commercial automobile insurance, commercial property insurance, homeowners insurance, personal automobile coverage, workers' compensation, reinsurance, and specialty lines. Notably, in a recent strategic move, Liberty Mutual announced plans to unify its personal lines products under its own brand name by 2026. This decision includes phasing out the Safeco Insurance brand, which the company acquired in 2008, marking a significant shift in its branding strategy.

The appointment of Timothy Sweeney as chairman signals Liberty Mutual's commitment to building on its strong foundation while adapting to the evolving insurance landscape. As the company embarks on this new phase under Sweeney's leadership, stakeholders will be keenly observing how he implements his vision for the future of Liberty Mutual.
