Testimonials from Valued AccuWeather Clients

Every forensic report replaces uncertainty with fact — reducing litigation time, claims costs, and investigative overhead.

“I have been most pleased with the services of AccuWeather generally and with Steve (Wistar) specifically. A seasoned claims representative was present in court to witness Steve’s direct examination and said later that he was the best trial expert he has ever seen. You can be sure that when I next need a weather expert witness, AccuWeather and Steve Wistar will be the first to get the call.”

“I just wanted to let you know that [insurance company] won the case yesterday. When I spoke to the jury afterwards, all 8 of them indicated that you were the reason that [insurance company] received a defense verdict. They liked the plaintiff very much and wanted to find for her. However, they found your expert testimony regarding the weather to be so compelling that they changed their minds and found for [insurance company]. I thought you made a fantastic witness.”
