Expert Witness

Expert witness for: personal injury attorneys, engineering firms, insurance companies, both plaintiff and defense. You want an expert witness with the background and the expertise to do the job correct, the first time.

  • Advanced Certified in Whiplash Injury Biomechanics & Mild Brain Traumatology
  • Certified Independent Chiropractic Examiner

Auto Accident Reconstruction is the scientific process of investigating, analyzing, and drawing conclusions about the causes and events during a vehicle collision. The laws of physics and engineering principles such as the conservation of linear momentum, work energy methods and kinematics are the basis for analysis. We can provide rigorous analysis in cases involving personal injury that can be presented at trial.

Our expert witness performs Medical Records Reviews and can also perform impairment ratings.

Dr Greg Hauser is qualified to perform crash analysis AND correlate collision information with injuries sustained in the collision (causation) as well as treatment. He has his certification from the Accreditation Commission for Traffic Accident Reconstruction (ACTAR). He is currently the ONLY physician in Arizona to have this certification. Usually this certification is acquired by police officers and engineers. This gives a unique, multi-faceted approach to cases where accident dynamics are in question, allowing him to render opinions on Accident Reconstruction as well as comment on the medical aspects of the case (injuries and treatment). This is useful for both Plaintiff and Defense.

You will not find this in any other expert witness in Arizona!
