Tarhanidis joins SiriusPoint with more than 25 years of investment leadership experience.

Her previous experience includes senior positions at MetLife, General Motors Asset Management, and Deutsche Bank.
She is also active in industry organizations, serving on the AIF Advisory Board, as a founding member of Women in Private Credit, and as a member of the Insurance Women’s Investment Network.
“Maria is a highly respected investment leader with deep expertise across asset classes and a great track record of delivering investment performance,” McKinney said. “Her strategic insight and knowledge will be instrumental as we continue to enhance our investment portfolio and support SiriusPoint’s growth ambitions.”
The sector is also seeing a broader adoption of sidecars, which are investment vehicles that allow third-party capital to participate directly in reinsurance risk. These structures have become a significant source of proportional reinsurance capacity, enabling insurers to manage claims volatility and diversify their capital sources.
“I look forward to working with Jim McKinney and the senior leadership team to build a world-class investment platform that drives value for our shareholders and supports our long-term strategy,” Tarhandis said.
