Liberty Mutual Insurance has appointed David Dwortz as president of Helmsman Management Services, Liberty Mutual's third-party claims administrator.

Mr. Dwortz succeeded Debbie Michel, who recently was appointed executive vice president of the national insurance casualty business at Liberty Mutual.

“Dwortz' background and skills make him the ideal candidate to lead Helmsman,” noted Mike Fallon, the president of the national insurance operations of Liberty Mutual. ”He has been with Liberty Mutual for 16 years, working in senior leadership roles in finance, underwriting, distribution, and claims. Most recently, he led distribution for commercial insurance, where he managed our largest agent and broker relationships. He also ran Liberty Mutual's complex claims unit, focused on mass tort litigation. Dwortz' experience will support even more focused investment and growth for Helmsman.”
