What Makes Claire Deliberately Different

Claire’s work begins with gaining an understanding of her clients’ goals, objectives and priorities. Claire’s representation is shaped by her experience as a litigator, in-house lawyer and insurance executive. Her knowledge of the insurance industry, its priorities and its constraints, informs her litigation strategy and judgment. 

Overview Overview Experience Credentials

Claire is a seasoned counselor and litigator experienced in a wide spectrum of insurance industry matters, ranging from coverage and bad faith litigation to regulatory proceedings. Her coverage litigation experience encompasses matters arising out of a variety of property, casualty, specialty and professional lines products, including wrap policies, captive plans and other industry-specific programs, as well as loss-sensitive plans subject to retentions, retrospective premiums and other risk financing mechanisms.

Before joining Sedgwick, Claire served as vice president and claim counsel for a major U.S.-based property and casualty insurer, where she was responsible for a nationwide portfolio of commercial and residential construction industry claims. Her in-house experience also extends to other high-exposure and long-tail claims, including those stemming from environmental clean-up costs and mass torts, as well as professional liability, intellectual property and employment-related disputes.

Representative Matters

Claire has a broad understanding of litigation matters stemming from potentially high severity claims, including those implicating exposure to multiple layers, years and types of coverage, including pollution and mass torts as well as claims based on allegations of commercial and large-scale residential construction failures, clergy abuse, and impairment of intellectual property rights and other proprietary interests.
