Parametrix announced on October 1, 2026, that Tresa Stephens had joined as Head of US Underwriting. She most recently led Cyber, Tech & Media for North America at Allianz Commercial. Parametrix says she will lead its US underwriting and help shape broader product strategy and development.
Who is Tresa Stephens?
Stephens is an insurance executive whose experience spans cyber, technology, media errors and omissions (E&O), and professional lines. Parametrix says she has more than 15 years of experience across those areas and has worked in underwriting strategy, product development, portfolio management, coverage architecture, and the operational frameworks for scaling specialty insurance portfolios. That description comes from the company’s announcement.
What is her new role at Parametrix?
As Head of US Underwriting, Stephens is to lead Parametrix’s US underwriting and support wider product strategy and development. Parametrix Head of Insurance Rick Wong said: “Tresa brings the combination of underwriting depth, portfolio leadership, and product expertise that is critical as we continue to scale our cyber business.”
Parametrix framed the appointment as part of its effort to grow its cyber and technology underwriting capabilities and develop insurance solutions for complex technology dependencies and digital infrastructure exposures. Those are the company’s stated goals; the announcement does not establish that the hire has already changed policy terms, products, market share, or customer outcomes. Stephens said: “Technology risk is evolving quickly, and that creates an opportunity to rethink how the insurance industry responds to these exposures.”
