Jason is an accomplished business litigator, with significant experience also representing corporate policyholders in a wide range of insurance coverage disputes. He serves as chair of the firm's Commercial Litigation group.

Previously, Jason served for five years as the Managing Partner of a Chambers-ranked boutique business litigation firm and then served for five additional years as the Managing Partner of its successor firm's Chicago office. As a result, he understands the challenges of running a business and brings a practical, results-oriented approach to his work.

That approach is best characterized by the title of a Chicago Daily Law Bulletin profile of his work, “Rosenthal Emphasizes Results Over Talk.” A Chicago Lawyer magazine profile of Jason also noted that “he sees the human dimension, the potential public perception, as well as the business perspective, and, most importantly, he finds ways to properly balance those interests.”

Those interests include finding insurance coverage to pay for litigation and other losses. As a result of his knowledge in this area, Jason has testified before juries and in arbitration as an expert witness on insurance issues, and he was elected as a Fellow of the American College of Coverage Counsel. He is a regular speaker, author, and commentator on both business litigation and insurance topics, and he previously served as a regular contributor to CPA Insider, a publication of the American Institute of Certified Public Accountants.
