By Amit Chowdhry • Feb 25, 2025

Dentons announced that Aidan M. McCormack and Mark L. Deckman have joined the Firm’s Commercial Litigation practice as partners in the New York office. And both are leading lawyers in the insurance industry with decades of experience representing insurance and financial services industry clients in a wide range of matters, including their complex exposures on the national and global level.

McCormack was US Chair and Global Co-Chair of his previous firm’s Insurance and Reinsurance Sector Practice. And he advises on and litigates insurance and reinsurance disputes and regulatory matters, across every line of coverage and across the world, including matters in the Americas, the UK, Europe, Asia and Australia.

Deckman also similarly handles complex coverage disputes and counsels on all areas of exposure to insurers. And Deckman has notable experience in the London insurance market, representing clients in high-exposure international arbitrations and litigations.

McCormack and Deckman join several other laterals who have joined Dentons US’ Litigation practice in recent months, including partners Richard Hong in New York, Peter Bekker in New York, James Newland in Washington, DC, and Jonathan Shulan in St. Louis, and counsels Brett Grindrod in Washington, Lyndy Chang Stewart in Oakland and Kaitlin Wallace in Honolulu.

These additions validates the firm’s investment in building a world-class litigation practice—growing in capacity for serving our clients and in prominence as a leader in the law globally.
