Debbie McLachlan

Product Head, International Casualty Treaty

Before joining Convex, I’d built up 25 years of reinsurance underwriting experience in various parts of the world, including continental Europe, Asia Pacific and Latin America.

Like my colleagues across the business, I was excited by the opportunity to help build an insurance company from the very beginning and to partner both with clients we have worked with for years as well as new companies.
