Clyde & Co LLP

The insurance practice at Clyde & Co LLP offers a strong bench of experts and wide geographic coverage, which the firm expanded in May 2021 as it opened three new offices across the southwestern United States. The team represents high-profile international and US insurers and reinsurers in a broad array of high-volume claims and disputes. Chicago-based practice head Eileen King Bower  draws on 30 years of experience in complex insurance coverage disputes, including many long-tail environmental and asbestos coverage matters. Paul Koepff in New York has advised clients most recently on significant matters relating to large multi-district litigations. Eric Hiller departed in January 2021, while in April 2021 Curtis Parvin retired and Margaret Holm departed the firm. That same month Amy Samberg joined the team from Foran Glennon Palandech Ponzi & Rudloff PC, bringing with her expertise as an advisor and a litigator in courts throughout the Southwest.
