Building Credible Testimony

An experienced and accredited consulting meteorologist can significantly impact a weather-related insurance claim or legal case. A comprehensive review by a qualified weather expert can verify if weather conditions were conducive for hail damage or provide plaintiff or defense attorneys in a slip-and-fall case with the details to confidently plead cases or cross-examine opposing expert reports.

An expert witness is key in accurately reporting the weather’s impact in a court case. Mark provides credible objective testimony on weather for a variety of legal cases from auto injury and accident cases to slip and fall and personal injury cases. Whether you’re the defendant or the plaintiff, hiring an expert witness who is also a Certified Consulting Meteorologist gives your case a huge boost.
