Seasoned Trial Lawyers & Litigators

Our lawyers have experience both as trial lawyers and litigators. We have tried over 100 jury trials to verdict in multiple jurisdictions. Our firm lawyers have litigated countless alternative dispute resolution proceedings, including mass mediations, arbitrations, and mini-trials. Our attorneys have acted as arbitrators and one of our attorneys also serves as a Magisterial District Justice. Because we represent large institutional clients in complex cases, we have vast experience with electronic discovery and managing document-intensive matters. Our clients demand, and we provide, unique experience and equipment to represent them in today’s technologically advanced environment.  McDonnell & Associates brings the right team to guide your case through any legal dispute with the goal of assisting you to make a sound and economically prudent decision.

National Consultants for Large Retailer

The firm’s lawyers frequently serve as national or consulting counsel on medically complex recurring claims, including allegations of Brain, Spinal Cord, and Neurological injuries. Firm attorneys are part of a national team of lawyers for large retailer specifically retained for their unique experience with the diagnosis, treatment and expert testimony involving Chronic Regional Pain Syndrome (“CRPS”), a controversial pain disorder. The firm also serves as national consultants on civil cases arising from criminal acts of third parties where there are allegations of inadequate security. In many of these matters, the firm’s attorneys conduct focus groups and opinion exercises to develop a winning strategy for trying the case.
