We have been investigating toxic tort cases since the early 1980’s and asbestos defense investigations since the early 1990’s.  We are experts at creating investigation plans that address both product identification claims and develop alternative exposure theories. Our expertise also includes locating witnesses on workplace conditions and events that occurred in previous decades; comprehensive witness interviews; drafting and executing witness declarations and affidavits, and process service of difficult or evasive parties. Asbestos investigations are conducted nationwide and abroad for both local and national clients and defense attorney firms.

We routinely receive assignments of all scopes and sizes. Please do not hesitate to inquire about matters ranging from a quick locate to the design and management of an investigative plan for your more complex litigation case files.
