Davis Walsh is a litigator who focuses his practice on representing public and private companies, predominantly in the automotive, medical device and transportation sectors, in state and federal court. He is the lead editor of Infectious Disease Litigation: Science, Law and Procedure.

Davis has developed expertise in all phases of litigation, including discovery matters, motions to dismiss, motions for summary and default judgment, motions related to expert admissibility, and post-trial motions for judgment and new trial. He has served in several litigation capacities during trial, most recently as trial counsel during an eight-week medical device trial in Washington state.

Davis’s experience goes beyond the courtroom. Prior to law school, he served as a Staff Assistant in the Office of Commonwealth Preparedness under then-Governor Timothy M. Kaine, and also served as the Legislative Assistant to State Senator R. Creigh Deeds. Davis brings this understanding of governmental operations and the need for rapid responses to clients’ needs both in and out of the courtroom to bear on behalf of clients facing governmental investigations, including OSHA workplace investigations.

In addition to his private practice, Davis is active in his community through pro bono service. He is co-lead for educational advocacy matters in the Medical-Legal Partnership – Richmond program, a partnership between the Children’s Hospital of Richmond at Virginia Commonwealth University, McGuireWoods and Dominion Energy which offers free legal advice and representation for eligible patients and families. He also partners with the JustChildren program to provide pro bono representation to juvenile offenders seeking release. As pro bono counsel, he has represented a client in a federal court defamation case as well as tenants in housing disputes.

Prior to joining McGuireWoods, Davis clerked for the Honorable Tommy E. Miller, Magistrate Judge for the Eastern District of Virginia. Through this experience, Davis gained substantial experience on discovery matters, which imparted an understanding of the importance of detail and precision in confronting all discovery matters.
