Leslie LeGrand, a partner, 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 traded in his bar card for a cloth collar. 

In addition to Leslie’s father, Leslie and his two sisters, along with four cousins, are members of the State Bar of Texas. Interestingly, at age 15 Leslie defended his first accused citizen as part of Harris County’s teen Court. 

Since then, he is a five time Super Lawyers  (2015, 2016, 2017, 2018 & 2019) by Thompson Reuters Service and he been has recognized four times as a Rising Star (2011, 2012, 2013, 2014)


Leslie is board-certified in Criminal Law by the Texas Board of Legal Specialization (TBLS) and has lectured 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 Harris County Criminal Lawyers Association. 

Leslie’s experience as a Harris County prosecutor, coupled with his above successes, makes him one of the most sought-after Houston DWI defense attorneys.


Before joining Trichter & LeGrand, PC, as a Houston DWI lawyer Leslie LeGrand was an Assistant District Attorney prosecuting misdemeanors and felonies at the Harris County District Attorneys Office. 

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. 

As an assistant District Attorney he has tried a wide variety of cases at both the felony and the misdemeanor levels, including juvenile matters, murder, aggravated sexual assault, aggravated assault, aggravated robbery, intoxication assault, intoxication manslaughter, and DUI/DWI.

Admitted to the State Bar of Texas in 2002, Leslie joined the Texas Criminal Defense Lawyers Association, the Harris County Criminal Lawyers Associations, the Houston Bar Association, the Texas Young Lawyers Association and the National College For DUI Defense.  

Leslie is motivated to provide the best possible defense to all his clients whereby he can return them to society without the blemish of the arrest affecting their future. 

In every case Leslie not only looks for a way to get the case dismissed or to have a not guilty verdict, but also, how to get the whole episode sealed from the public or expunged (having all the records erased or destroyed).
