Diana M. Karnes


What Makes Diana Deliberately Different

Having spent six months as a secondee at an insurance company, Diana understands firsthand the commercial aspects of insurance and the importance of business relationships. This knowledge, coupled with her practice as both a defense attorney and a coverage attorney, provides her with a unique and comprehensive perspective to each case she handles. Armed with this knowledge and a keen attention to detail where necessary, Diana uses creativity and civility to find efficient and effective resolutions.

Overview Overview Experience Credentials

Over the last decade, Diana has divided her practice into two areas, as an insurance coverage lawyer and as a litigator directly defending companies in various types of personal injury actions. Diana's coverage experience includes acting as monitoring counsel for insurers in the Bermuda market involving directors and officers, employment practices and other types of professional liability, as well as general liability matters. Her litigation background includes product liability, healthcare and other litigation matters. Most recently, in 2016, Diana did a six-month secondment with Markel Service Incorporated, where she focused her skills on insurance. During the secondment, Diana worked with Markel’s U.S. Professional Liability Medical Team where she handled claims, analyzed coverage under professional and general liability policies, and assessed potential exposure of matters noticed to cyber excess policies.
