Marshall Dennehey has once again been recognized as a leader in client service, earning a spot on BTI Consulting’s Client Service A-Team 2025, which honors law firms delivering the highest levels of service to corporate clients. The firm also attained A-Team status in 2024. 

Marshall Dennehey announced that it has added the majority of the talent and existing business of Pittsburgh-based civil defense litigation firm Walsh Barnes, P.C. The move brings seven attorneys, including former Walsh Barnes named partner Adam M. Barnes and two other shareholders, to Marshall Dennehey's Pittsburgh office. Paul J. Walsh, III, founder and managing partner of Walsh Barnes, is stepping away from active litigation after 35 years and will devote his full attention to mediation. Walsh Barnes will be closing as of July 31, 2025.

Marshall Dennehey was awarded the prestigious Litigation Department of the Year awards for Professional Liability and Appellate Law at The Legal Intelligencer’s 2025 Pennsylvania Legal Awards, held June 12 in Philadelphia. 

Marshall Dennehey is proud to announce that two of the firm’s practices have received top recognition in the 2025 edition of Chambers USA.
