Trevor Riddle spent his high school years in rural Oklahoma earning All-State credentials as an offensive tackle.

This unique meld of competitive instinct and philosophical scientific insight has become a cornerstone of Mr. Riddle’s defense practice. 

Since joining Monnat & Spurrier, Chartered, eight years ago, Mr. Riddle has fought for his clients by cross-examining forensic laboratory technicians, medical doctors and other expert witnesses. He has also advocated for his clients by the presentation of experts ranging from pathologists to biomechanical engineers. Mr. Riddle was also the first attorney in Kansas to argue the admissibility of polygraph evidence under Kansas’ recently amended rules of evidence.

Mr. Riddle earned his Juris Doctorate from the University of Kansas School of Law in 2005. While in law school Mr. Riddle clerked for the Douglas County Kansas District Attorney and, after law school, prosecuted and tried cases as an Assistant Butler County Attorney.
