Greg Barats, CEO and President, HSB Group

Jeffrey C. O’Shaughnessy has been appointed to succeed Barats as CEO and President of HSB, and Kathleen O. Zortman will assume the role of CEO and President of American Modern. The appointments are effective March 2, 2026. Both O’Shaughnessy and Zortman will work closely with their predecessors over the coming months to ensure continuity and the continued success of their respective businesses.

“Greg and Andreas have each made lasting contributions to Munich Re’s success and to the industry at large,” said Mike Kerner, Member of the Board of Management responsible for Global Specialty Insurance (GSI) at Munich Re Group. “Their leadership has helped shape HSB and American Modern into organizations known for expertise, stability and partnership. Munich Re remains deeply invested in these parts of our value proposition along with delivering solutions that help our clients and partners succeed.”

“As Munich Re Specialty continues to expand our specialty insurance footprint worldwide, these leadership transitions underscore our commitment to sustainable growth, innovation, and leadership development within Munich Re Group,” said Kerner.

Barats, who was named CEO in 2011, has overseen the exceptional growth and performance of HSB as a leading provider of specialty insurance, global engineering, and technology services in the U.S., Canada, U.K., and Ireland. He serves on the Munich Re Global Specialty Insurance Executive Board, heads up Munich Re’s Global Internet of Things (IoT) business, and is responsible for the global Artificial Intelligence (AI) and Generative AI insurance initiatives of HSB and Munich Re.

He has served on the Hartford HealthCare Board of Directors since 2019 and his commitment to the greater Hartford community has included support for many charitable organizations.

“My time at HSB has been the most rewarding of my professional career,” said Barats. “I am proud of the work our team of employees around the world has accomplished over the past 15 years, harnessing innovation, engineering, and technology to help transform the future of specialty insurance and risk management. HSB is well-positioned to continue to create new solutions for the exposures of tomorrow.”

Kleiner, who has served as CEO and President of American Modern since 2016, successfully guided the company through a multi-year transformation that enhanced operational efficiency, employee engagement, and the customer experience. Over his 30-year career with Munich Re, Kleiner has held senior leadership roles in the U.S., Europe, Asia, and Africa, bringing a truly global perspective to every position he has held.

He serves on the Munich Re Global Specialty Insurance Executive Board, and under his leadership, American Modern has been recognized as a “Cincinnati Top Workplace” for the past decade.

“I have thoroughly enjoyed the last 10 years at the helm of American Modern,” said Kleiner. “I have had the honor of working with a great team, and jointly, we have achieved a great deal. It has been a very rewarding experience, and I will look back with very, very fond memories. I believe that American Modern is across the board well-positioned for the future, which leaves me feeling positive as I hand over the baton to my successor.”

O’Shaughnessy, who joined HSB in 2002, is president of HSB Portfolio Risk Solutions, managing HSB’s assumed reinsurance business and overseeing the division’s products, underwriting, and relationships with client insurance companies and strategic partners. Previously, he served as global chief underwriting officer and has led the development of a number of HSB’s strategic products over the years.

Zortman brings more than 30 years of experience in property and casualty insurance, with a strong record of leading organizational transformation, optimizing portfolios for sustainable profitability, and building high-performance teams that deliver operational and underwriting excellence.
