These cases each carry their own challenges, but they all begin with the same foundation: a careful review of the State’s claims and a plan for how to respond.

A Hands-On Defense Led Personally by Our Founding Attorney

When you hire The Law Office of Rene A. Flores PLLC, you work directly with the lawyer who built the firm. Attorney Rene A. Flores grew up in the courthouse, first watching his mother practice law, later serving as an Assistant Court Coordinator, and eventually becoming a prosecutor and a long-standing Municipal Judge. Those experiences shaped how he approaches every case. He does not hand clients to junior staff or rotate cases between attorneys. He stays involved from the first meeting through the final resolution so you always know exactly who is reviewing your evidence and who will stand beside you in court.

That level of involvement shapes the way your defense is built. You work with an attorney who knows your file in full, who can spot details that matter, and who makes himself available for questions as the case develops. It is a hands-on approach driven by experience, rooted in accountability, and built to serve the people who place their trust in us.

Work with the Only Forensic Lawyer-Scientist in South Texas

Criminal cases in San Antonio often hinge on lab reports, chemical testing, and technical evidence that most people never see beyond a final number or conclusion. Attorney Flores brings a perspective that is uncommon in Texas. He is the only attorney in South Texas who has completed the demanding coursework and passed the examination required to earn the ACS-CHAL Forensic Lawyer-Scientist certification. This distinction allows him to review the State’s scientific evidence with a level of precision that is not widely available in the region.

This certification matters because many charges rely on testing that appears straightforward on paper but is far more complex in practice. Blood alcohol measurements, drug identification, and chemical composition analysis each have vulnerabilities that can affect the outcome of a case. With advanced training in forensic chromatography, Attorney Flores can assess whether those results meet scientific standards.

For you, this means your defense is informed by someone who understands the science behind the allegations and who treats every test result as something that must be verified, not simply accepted.

We Build a Defense Strategy Around the Local Justice System

Attorney Flores’s background includes years as a prosecutor and many years on the bench as a Municipal Judge. He has seen how charging decisions are made, how evidence is evaluated behind closed doors, and how San Antonio courts expect cases to be prepared and presented. That perspective guides every defense strategy we develop.

Working with The Law Office of Rene A. Flores PLLC means having an attorney who understands:

• How local agencies document investigations and where procedural problems tend to surface
• How prosecutors measure the strength of their evidence before pursuing a plea or moving toward trial
• How judges view timelines, motions, and the level of preparation they expect from both sides
• How to identify weak points early so the defense can address them before they shape the rest of the case

We review every angle with the same level of scrutiny that prosecutors bring to their own files. Reports, recordings, warrants, digital data, and laboratory material are all examined with a focus on accuracy, legality, and context. The goal is simple: build a defense that is fully informed, grounded in the realities of San Antonio’s courts, and positioned to pursue the most favorable outcome possible.
