I specialize in providing expert witness services tailored to lawyers and attorneys handling injury cases nationwide.

As a renowned retail expert witness, I bring extensive expertise in slip and fall cases, including slip and fall retail cases, trip and fall cases, and commercial injury cases.

I provide top-tier slip and fall expert witness opinions, retail injury expert witness observations, and commercial accident witness analysis, all with a deep understanding of retail design and commercial accident dynamics.

Whether you need a retail design expert witness, a restaurant injury expert witness, or a commercial slip expert witness, I offer comprehensive insights and testimony to support your case.

My expertise spans across retail, commercial, hospitality and restaurant settings, providing critical analysis and testimony for slip and fall, trip and fall, and other retail and commercial accidents.

How I Work with Out-of-State Attorneys and Law Firms

I have successfully worked with attorneys across 48 U.S. states, providing expert witness services in a wide range of injury cases. My ability to work with out-of-state attorneys is made possible by utilizing detailed photos, videos, and descriptions provided by the attorney to understand the incident. Through virtual walkthroughs, I can assess the accident scene remotely, offering the same in-depth analysis as an in-person visit.

Additionally, I have extensive experience participating in live depositions virtually, which allows me to seamlessly contribute to your case regardless of location. For attorneys looking to manage budgets and reduce costs, my virtual participation is a cost-effective solution. However, I am also available for in-person attendance if needed to strengthen your case.

William Barr, Jr. – Wichita, KS

Jerry – Thanks for your help in settling this matter. Thanks to the strength of your liability report Defendant chose to settle rather than fight. It’s certainly a pleasure to resolve a case early on without discovery or further effort. Your report did the trick! Thanks – Bill

Arce Dwyer – Omaha, NB

Jerry, Our case with Nike has settled, I suspect in no small part because your report scared the crap out of plaintiff’s counsel. Good work.

Easter P. Moses – Roanoke, VA

Jerry, This case has settled.

The testimony of a Wal-Mart employee at the depositions prompted Wal-Mart to settle.

Thank you for all of your assistance and cooperation. Your work was outstanding. Your report was very thorough and persuasive.

Most of all, it was a great pleasure to work with you. I will certainly utilize your expert services in the future should the need arise, and refer any colleagues that ask me about an expert witness in your area of expertise.

This was a challenging case.
