Thomas Welling
Thomas Welling is a seasoned litigator with trial experience who represents businesses and individuals facing complex commercial disputes, including mergers and acquisitions, corporate governance, insurance coverage, and contract disputes; securities litigation; class actions; business torts; and bankruptcy-related matters. Thomas applies his considerable knowledge of federal securities, corporate governance, real estate, class action, insurance, antitrust, advertising, and bankruptcy laws to devise aggressive and efficient ways to reach desirable solutions. Clients also seek his counsel pre-transaction to avoid and manage litigation risks. In addition, Thomas has considerable experience representing nonprofit organizations.

Thomas has extensive experience representing both plaintiffs and defendants in federal and state courts in New York and throughout the United States, and in private mediations and arbitrations.

Thomas began his career at Simpson Thacher & Bartlett LLP, where he was a litigation associate. He gained valuable trial experience through his involvement in such matters as a $100 million-plus jury trial, a multi-billion-dollar non-products asbestos coverage dispute fought in a multiphase bench trial, and a bankruptcy confirmation hearing of a 524(g) plan on behalf of the same insurer.
