WHAT ATTORNEYS SAY

Client Testimonials

“Jurors described you as ‘awesome,’ that you ‘knew your stuff,’ and that you and that your testimony was ‘very impressive.’ Also, one juror commented that you were more comfortable in the courtroom than any other witness. ‘Corporate representative who monitored the trial thought you were an incredible witness and one of the best she has seen.'”

— Margo P.

Personal Injury Attorney

“His analysis and presentation of tractor trailer electronic data and documented extreme winds at the time of the crash was critical in proving our case. The data he recovered, organized and explained to the jury was exceptional.”

— David T.

Partner, Defense Law Firm

“He was the only witness that the jury listened to in a case involving wheel loss of a tractor trailer. He brought actual parts to explain the component failure. I highly recommend Dr. McElroy. His 40+ years of experience show in the detail nature and quality of his work and his professionalism.”
