Our Work - For over 30 years we have specialized in the investigation, engineering analysis, and reconstruction of accidents and incidents causing injury, death and property damage, and the engineering analysis of the safety of products, equipment and facilities involved in accidents and incidents. We have performed this work for both plaintiffs and defendants over this whole period.
The results of our work can be, and are regularly, presented in client consultations, written expert reports, and affidavits, as well as in expert testimony in deposition, arbitration and trial. The presentation of the results of our work is determined by the requirements for the matter, and as requested by the client.
