Overview

Arthur McColgan has more than 30 years of experience counseling clients and arguing cases in state and federal courts across the country.

His practice focuses on litigation for insurance companies and corporate clients involved in complex coverage and business disputes. Insurers retain Arthur as coverage counsel in connection with professional liability claims, personal and advertising injury claims, first party property claims, mass tort claims, and long tail exposures. In addition, he has considerable experience in defending clients against statutory violation claims in individual and class action cases filed in state and federal courts. Arthur also assists clients in general commercial litigation matters and disputes, including breach of contract actions. Outside of the litigation context, Arthur provides counsel to insurer clients on coverage, claims handling, and bad faith issues in jurisdictions across the country.

Arthur has substantial experience in managing complex litigation. His clients value his strategic planning and organizational ability as lead counsel on cases involving multi-million-dollar exposures, enormous data sets, and copious depositions. Arthur has a proven record as a resolute but pragmatic negotiator in connection with dozens and dozens of intricate settlements achieved on behalf of his clients. He has extensive experience in resolving perplexing litigation through alternative dispute resolution mechanisms as well.

Arthur began practicing law due to his love of solving intellectually challenging legal issues. His passion for solving legal problems is as strong as ever and is most evident in the energy with which Arthur represents the interests of his clients in contentious litigation and in his counseling of clients to avoid costly disputes in the first instance. Arthur is chair of the firm's Pro Bono Committee and recently became Walker Wilcox's CEO.
