Houston DWI lawyer Leslie LeGrand

Leslie LeGrand (Board Cert. Criminal Law)

Leslie LeGrand is a Houston DWI lawyer and native Houstonian who was born into the legal profession. In 1937, his grandfather began the LeGrand family tradition of practicing law in Texas courts, which he continued until he received a calling to trade in his bar card for the cloth. In addition to Leslie’s father, Leslie and his two sisters along with four cousins are members of the State Bar of Texas. Leslie defended his first accused citizen at the age of 15 as part of Harris County’s teen court.

Leslie LeGrand is a Recognized Houston DWI Lawyer

Since then, he has become a four-time recognized Rising Star of DWI Defense Attorneys by Texas Monthly (2011-2014) and has been recognized as a Super Lawyer two years in a row by the same publication. He is board-certified in Criminal Law by the Texas Board of Legal Specialization and has been asked to lecture at numerous DWI seminars. Leslie was also recognized as one of the 10 Best in Client Satisfaction by the American Institute of DUI/DWI Attorneys (2015). Leslie is a member of the National College of DUI Defense, the Texas Criminal Defense Lawyers Association, and the Houston Criminal Lawyers Association. Leslie’s prior experience as a Harris County prosecutor makes him one of the most sought-after Houston DWI defense attorneys.


Before joining Trichter & Murphy, PC, as a Houston DWI lawyer Leslie LeGrand was Assistant District Attorney, Felony Prosecutor, Harris County. He has also served as Assistant District Attorney, Juvenile Prosecutor, 315th District Court, and Chief Misdemeanor Prosecutor in County Criminal Court as well as Misdemeanor Prosecutor, Texas.

Leslie was admitted to the State Bar of Texas in 2002 and is a member of the Texas Criminal Defense Lawyers Association, the Houston Bar Association, and the Texas Young Lawyers Association.
