"We're delighted to welcome Sarah to our Portfolio Solutions team. Her deep cross-class experience, technical expertise, and ability to develop innovative solutions make her a stand-out addition as we continue to grow our capabilities. As demand for portfolio-based insurance continues to grow, driven by digital placement, algorithmic underwriting and diversified risk strategies, Sarah's insight will be invaluable as we enhance our capabilities and expand our position in this evolving market."
In her new role, Tidbury will focus on assessing and structuring portfolio deals across multiple lines of business and geographies, working closely with brokers and clients to tailor solutions to their needs as TMK continues to broaden its technical expertise and market reach.
