Berkshire Hathaway Specialty Insurance has promoted two executives within its Healthcare Professional Liability business as the insurer continues to expand its healthcare underwriting operations in the United States.

Effective immediately, Jarek Chmielowski has been named healthcare institutions portfolio manager, while Greg Struhar has been promoted to national underwriting manager for healthcare institutions, reporting to Chmielowski, the company announced Wednesday.

In his new role, Chmielowski will oversee portfolio strategy, underwriting performance and market expansion for BHSI's healthcare institutions business nationwide. Struhar will lead national underwriting execution, working with underwriting teams across the country to provide healthcare professional liability coverage and services to customers and brokers.

He said Chmielowski brings "exceptional underwriting expertise, strategic vision and market perspective," while Struhar's healthcare experience and leadership make him well suited for his new role.
