Switzerland-based reinsurer MS Reinsurance has hired Lisa Butera from Swiss Re to serve as Chief Underwriting Officer (CUO) for North America (NA), and has also expanded Lucas Castagnino’s role to CUO for Latin America and Caribbean.

Butera brings more than three decades of leadership experience across insurance and reinsurance markets to MS Re. She joins from Swiss Re, one of the world’s largest reinsurance companies, where she most recently served as Managing Director, Head of FinPro and Casualty, North America, Corporate Solutions.

Castagnino, who joined MS Re in 2016 and currently serves as Head of Latin America and Caribbean, has been named CUO for Latin America and Caribbean, a move which broadens his role and elevates the region in the company’s business.

He has thirty years of experience and strong track record of leadership, and MS Re expects Castagnino to continue to drive its goals across Latin American markets.

Jörg Bruniecki, Group Chief Underwriting Officer, said: “Today marks an important step in strengthening our underwriting leadership. Lisa’s and Lucas’s experience, leadership skills and perspectives will help us build on the momentum we have already created.”

“These appointments follow a comprehensive search process, which included both internal and external candidates, highlighting the strength and depth of talent within MS Re’s underwriting organization. With this team in place, I am confident in our ability to deliver on our underwriting strategy and continue to create value for our partners in the Americas,” added Bruniecki.
