Liberty Mutual has announced the appointment of Dennis Cook (pictured) as president of IronHealth, the healthcare professional liability and stop-loss unit of its IronShore business.
In his new role, Cook will drive the profitability and growth of an organization that services the risk management needs of hospitals, healthcare providers, managed care organizations, life science companies, senior care facilities, and self-insured employer health plans.
Cook joined Liberty Mutual four years ago and most recently served as IronHealth’s chief liability officer, where he successfully led an operation with $220 million in gross written premiums. Prior to joining Liberty Mutual, Cook held several senior positions at AIG.
“Dennis has demonstrated success growing a profitable healthcare insurance business of scale,” said Mathew Dolan, North America specialty president at Liberty Mutual. “He has the perfect blend of healthcare underwriting, product management and leadership skills to continue IronHealth’s growth as a leading provider of specialty solutions.”
Headquartered in Boston, Liberty Mutual is the sixth-largest global property and casualty insurer based on 2020 gross written premium. The firm employs over 45,000 people in 29 countries and economies around the world.
