Emergency Medicine & Medical Toxicology Expert Witness

Dr. Stephen L. Thornton is one of our top experts specializing in emergency medicine and medical toxicology.  He consistently receives the highest praise from both plaintiff and defense attorneys.

Dr. Thornton graduated from Kansas State University with a bachelor’s degree in biochemistry in 1997 and obtained his MD degree from the University of Kansas in 2001.  After completing a 4-year emergency medicine residency at the University of California - Fresno he returned to the Kansas City area, where he worked in a variety of settings including rural, suburban and academic medical centers.  He completed his postgraduate education in 2012 with a 2-year fellowship in medical toxicology at the University of California - San Diego.  He again returned to the Kansas City area, this time as a core faculty member of the University of Kansas Emergency Medicine Residency Program and as the medical director of the the Kansas Poison Control Center.  He became board certified in emergency medicine in 2006 and in medical toxicology in 2012. 

Dr. Thornton currently has an active clinical practice in emergency medicine and medical toxicology at a quaternary care academic medical center and a VA hospital, as well as a medical toxicology practice at a children’s hospital.  He has been providing expert witness services for almost 5 years, including dozens of cases for both plaintiff and defense attorneys.  He is committed to providing expert medical opinions supported not only by his training and experience, but also by the latest research and medical literature.  With his unique experience as an emergency medicine physician and a medical toxicologist, he can translate lab results to real-world clinical data and correlate physical exam findings with drug levels.  This includes dealing with common drugs such as alcohol, marijuana and prescription opioids, as well as novel synthetic drugs, e.g., fentanyl and other synthetic opioids, spice and other synthetic cannabinoids, “bath salts,” etc.
