Our work

Clients in litigation or with special projects retain our services. We are often consulted following major losses to perform research, examine products, inspect facilities, and perform field studies. We advise clients on regulatory compliance, applicability of research and standards, and other issues within our expertise.


A human factors expert investigates how people interact with a product or other elements of a system. Describing human performance in a multi-faceted and complex situation necessitates the specialized education, training, and experience we have provided to lawyers, insurance companies, and businesses for over 25 years.
