Toxicology Litigation Consultants is a forensic toxicology consulting and expert witness firm based in Georgetown Texas. We provide services to civil defense and plaintiff counsel as well as criminal defense attorneys.

The firm was established in 1997 by Ronald H. Tisdell.

Originally trained and licensed in Canada, Mr. Tisdell attended graduate school specializing in clinical toxicology and pharmacology at the University of Texas Health Sciences Center in San Antonio. Following his tenure in San Antonio, he served as a founding member of the Texas State Poison Center at the University of Texas Medical Branch in Galveston, Texas. He served as a clinical preceptor to students and residents at UTMB where his activities included clinical care, research and education. In 1987, he was appointed Director of Clinical Drug Information Services at the University of Alberta Hospitals in Edmonton, Canada. In his capacity he served on the hospitals' Pharmacy and Therapeutics Committee for the 1000+ bed tertiary care teaching facility, and directed development and enforcement of institutional drug utilization and accountability policies. In 1996 he returned to Texas to pursue full time forensic toxicology activities. He has served as an expert in the field of toxicology and pharmacology before courts, coroner's inquests and administrative hearings throughout the United States and Canada. Mr. Tisdell has published scientific works in peer reviewed literature and retains membership in respected professional societies in Canada and the United States.  He is currently a member of the Southwest Association of Toxicologists, the Alberta College of Pharmacist, Texas Criminal Defense Lawyers Association, National Criminal Defense Lawyers Association.

Our goal is  to provide our clients with an interpretation of  facts based on scientifically accepted and epidemiologically proven principles set forth in peer reviewed scientific literature. 

Through the application of our knowledge, skill, training, and ability we bring together the expertise that attorneys, courts and juries rely on when making tough decisions in civil and criminal litigation.

Our offices located in Central Texas are within a short travel time to our clients throughout the State of Texas. 

Although our practice is based in Texas we are available to work with legal professionals throughout the United States, Canada and Europe. 

We are proud of our participation in dispute resolution involving men and women in the United States Armed Forces.
