also known as Mario DelPrado
I am Mario Del Prado, a San Antonio criminal defense lawyer. I am Board Certified in Criminal Law by the Texas Board of Legal Specialization. I defend people charged with serious felonies in Bexar, Guadalupe and surrounding counties: murder and homicide, sexual assault and other sex offenses, aggravated assault and family violence, robbery, and drug charges.
I started my career in 1986 as an Assistant District Attorney in Bexar County. From 2019 to 2022 I returned to the District Attorney's Office as Chief of the Criminal Trial Division and then Chief of Major Crimes. I know how the State builds these cases and where they break.
I take a limited number of cases, and I answer my own phone.
Assistant District Attorney, Bexar County 1986–1991.
Chief, Criminal Trial and Major Crimes, Bexar County DA 2019-2022.

Former Client
Mario is an excellent lawyer and a complete professional. I had full trust in Mario during the entire process. I appreciated the honesty with which he communicated with me.

You Will Be Well Served
Mr. Del Prado kept my DWI probation from being revoked. Everyone knows that there are many intelligent and experienced lawyers to choose from.

"I endorse this lawyer. Mario has been doing this a long time- he knows all the tricks and is a great talent!! =)"
"I have had the pleasure of both opposing Mr. Del Prado on criminal cases from a former career as a felony prosecutor, to consulting and working with Mr. Del Prado as a criminal defense attorney. In every instance, I can attest that he has a thorough understanding of the law and criminal procedure and is adept at finding strategic solutions to benefit his clients. As a fellow board certified attorney, Mr. Del Prado has taken the additional step of passing a state sponsored certification exam to achieve special certification in criminal law. He puts that experience and expertise to work for his clients and they are the better for it. He is one of the few attorneys I would consult on any criminal legal issue of merit and has proven himself to be a very good trial lawyer."
