Our Expert Witness Process

Search Search

We scour the globe, leaving no stone unturned, and perform a uniquely designed exhaustive search to find the best available talent.

Search Vet

We dive deep to consider other witness attributes, such as disposition, litigation history, academic and industry experience, and any other characteristics pertinent to assuring the success of your trial.

Search Align

Our process allows you to focus on your case rather than on administrative concerns, while we work diligently to ensure a smooth expert engagement.

Search Prepare

IMS strategy advisors work with you and your experts to formulate the best strategies for structuring reports and trial testimony. Our jury consulting team assists with witness preparation so opinions are communicated clearly. Our graphic designers create graphics and animations, for both the report and trial, that assist witnesses with teaching and persuading fact finders. Our trial technicians seamlessly incorporate basic educational tools and utilize other techniques that assist experts during their testimony.
