Del Prado Law: Two Bexar County Prosecutors Who Fell in Love and Switched Sides Together

TO OUR READERS: This profile is independent editorial content produced by Awesome Attorneys. Del Prado Law did not pay for, commission, sponsor, or review this article, and inclusion in this series cannot be purchased. Nothing here is legal advice, an endorsement, or a recommendation to hire any lawyer; readers should evaluate counsel independently and may verify any Texas attorney’s license and discipline history through the State Bar of Texas at texasbar.com. Facts are drawn from the sources identified in the Methodology section and were verified as of August 2026.

AT A GLANCE

I. Two Prosecutors Who Met, Married, and Went Into Defense Together

Mario and Christine Del Prado’s origin story is unusual even among San Antonio’s many husband-and-wife legal partnerships: both started their careers as Assistant Criminal District Attorneys for Bexar County, where they met, worked together, and successfully prosecuted a murder case as colleagues before marrying. In 1991, they left prosecution to found their own defense firm, and have practiced together, in the same firm, for more than three decades since. Mario’s career took one more notable turn along the way: in 2018, he returned to the Bexar County District Attorney’s Office for four years, this time as Chief of the Criminal Trial Division, supervising more than 40 felony-level trial lawyers, before returning to private defense practice in 2022.

II. A Full-Spectrum Criminal Defense Practice

Del Prado Law’s practice spans the full range of Texas criminal defense, from misdemeanors through capital murder. The firm specifically lists DWI/DUI alongside more serious felony categories including homicide, sexual assault, domestic violence, and white collar crime, rather than treating DWI as a separate, lower-priority category.

III. Practice Areas

• DWI/DUI defense
• Homicide and capital murder
• Sexual assault and sex crimes
• Domestic violence
• Drug crimes
• Theft and robbery (property crimes)
• White collar crime
• Federal criminal defense
• Expunctions

IV. Case Outcomes

The firm’s public materials describe having “successfully handled every kind of criminal case imaginable” and having achieved “acquittals, dismissals, and reduced charges” across 35-plus years, but do not publish an itemized list of individual case results with specific charges and outcomes; that gap is disclosed here rather than filled in.

V. The Client Voice

One Avvo reviewer wrote that the Del Prado Law firm “cared about me and treated me with the utmost respect and attention,” crediting Mario and Christine with “saving me from a charge that would’ve radically changed my life for the worse,” and calling the outcome “something I could have only dreamed about.” Another reviewer described being impressed with Mario’s intelligence from the first conversation, writing that he “genuinely wanted to help me.” No pattern of negative or unresolved reviews was located for this firm as of this research date.

VI. Community and Local Presence

The firm has operated from the same Woodlawn Avenue address in San Antonio for its entire 30-plus-year history. Mario’s four-year return to public service as Chief of the Bexar County DA’s Criminal Trial and Major Crimes Divisions (2018-2022) is documented career history rather than an ongoing civic program; no separate current pro bono initiative is documented on the firm’s public materials.

VII. Credentials and Recognition

Mario Del Prado is board certified in Criminal Law by the Texas Board of Legal Specialization and separately certified in Criminal Trial Advocacy by the National Board of Trial Advocacy, both genuine peer- and exam-based credentials. He has been named a Texas Super Lawyer in multiple years, a third-party peer-review recognition distinguished here from self-conferred marketing claims. No independent certification record was located for Christine Del Prado as of this research date; that gap is disclosed rather than assumed away.

VIII. The Texas Legal Backdrop

In Texas, a first-offense DWI is generally a Class B misdemeanor, escalating with aggravating factors under Texas Penal Code Chapter 49. Homicide and capital murder charges, both part of the firm’s documented practice, carry the state’s most severe sentencing exposure, including the death penalty in capital cases, and follow a substantially different procedural track than misdemeanor matters. None of this is legal advice; consult a licensed Texas attorney about your specific situation.

IX. The Awesome Attorneys Assessment

Del Prado Law’s structural strength is a genuinely unusual origin story turned durable partnership: two former Bexar County prosecutors, one of whom returned to lead the DA’s Major Crimes Division mid-career before coming back to private practice, now running a single firm together for more than three decades. For a San Antonio client facing a serious felony charge who wants attorneys who understand the prosecution’s playbook from direct, recent institutional experience, that combination is a real, checkable asset.

The honest limitation is one worth naming for any two-attorney firm handling the full range of criminal matters from misdemeanors to capital murder: a client should ask directly which of the two attorneys will be lead counsel on their specific matter and how the firm allocates attention across simultaneously active cases of very different severity and complexity.
