Expert Witness and Litigation Support

At Nave Newell, we have served as expert witnesses in over 20 litigation cases, appearing before both the Court of Commons Pleas and Commonwealth Court.

Our civil engineering and land planning experts bring strong credentials, technical expertise, and the ability to testify and work as part of a trial team. We are known for our thorough expert reports, clear and effective exhibits, and convincing testimony.

We look at the big picture and get a full understanding of the attorney’s legal strategy. We complete a comprehensive evaluation of the project and case materials. We identify our weaknesses as well as those of the opposing side. We then provide the technical data necessary to support the case and help resolve issues outside of court, whenever possible.
