Why Choose Spangler Law?

A Decade of Criminal Defense — Nothing Else

Attorney Jim Spangler began his career as a public defender in Indiana and Dallas before founding Spangler Law. Criminal defense is all we do. That singular focus means every strategy, every motion, and every courtroom argument is built specifically to fight Texas criminal charges — not split between unrelated practice areas.

850+ Case Dismissals and Counting

Results matter. Since 2014, Jim and the Spangler Law team have secured over 850 case dismissals and achieved victories in numerous felony trials. Our record across DWI, drug crimes, assault, murder, and weapons cases speaks for itself. Even charges that look overwhelming can be dismissed or reduced with the right defense attorney.

Personalized Strategy — Not a One-Size-Fits-All Approach

Every criminal case is different. We take the time to understand your circumstances, scrutinize the prosecution’s evidence, and build a defense tailored to your specific charges and goals. You’ll always know where your case stands and what your options are.

Comprehensive Criminal Defense Services

DWI Defense

Texas DWI charges carry serious penalties — license suspension, heavy fines, and jail time. We challenge breathalyzer accuracy, blood test procedures, and the legality of traffic stops to fight your charges from every angle.

Drug Crimes

From simple possession to trafficking and distribution, our attorneys understand the Texas Controlled Substances Act inside and out. We scrutinize search and seizure procedures and work aggressively to reduce or dismiss your charges.

Assault & Family Violence

Assault charges — including domestic and family violence — can arise from misunderstandings and one-sided police reports. We investigate what really happened and build a defense that reflects the full picture.

Murder & Violent Crimes

When the stakes are highest, you need the strongest defense. Spangler Law has the experience and determination to defend clients against murder, manslaughter, and other violent crime charges in Dallas County courts.

Theft, Robbery & Burglary

Theft charges range from misdemeanor shoplifting to felony robbery. We analyze every element of the alleged offense — intent, identification, and value — to challenge the prosecution's case and protect your record.

Weapons Offenses

Texas gun and weapons laws are complex. Whether you're facing an unlawful carry charge, a felon-in-possession allegation, or a weapons charge tied to another offense, we know how to defend your Second Amendment rights.

Critical Mistakes That Can Cost You Your Case

Talking to Police Without a Lawyer Present

Anything you say after an arrest — even in casual conversation — can and will be used against you. Invoking your right to an attorney immediately is one of the most important things you can do to protect your defense.

Waiting Too Long to Hire Defense Counsel

Evidence can disappear fast. Dashcam footage gets overwritten. Witnesses become harder to locate. The earlier Spangler Law is on your case, the more tools we have to build your defense and challenge the prosecution’s evidence before it solidifies.

Assuming a DWI or Drug Charge Is “Open and Shut”

Even charges that feel inevitable often have critical weaknesses — improper stops, faulty test equipment, chain-of-custody issues, or constitutional violations. A skilled criminal defense attorney can find those weaknesses and exploit them on your behalf.

Hiring a General Practice Attorney for Criminal Charges

Texas criminal law is a specialized field. General practitioners are unfamiliar with bar advertising rules, DWI science, local prosecutorial tactics, and courthouse dynamics. Spangler Law focuses exclusively on criminal defense — and it shows in our results.

How Spangler Law Fights Your Case

Free Case Review

Contact us 24/7. We listen to the details of your charges, walk you through your rights, and give you an honest assessment of your case and your options — at no cost.

Evidence Review & Investigation

We obtain and analyze police reports, bodycam footage, breathalyzer records, witness statements, and every piece of evidence the prosecution plans to use — looking for weaknesses to challenge.

Customized Defense Strategy

No two cases are the same. We build a strategy specific to your charges, your record, and your goals — whether that means negotiating a dismissal, securing a plea reduction, or taking the case to trial.

Aggressive Courtroom Advocacy

Jim Spangler is a seasoned trial attorney who started in the public defender's office. If your case goes to trial, we're prepared to fight — with skill, confidence, and an unwavering commitment to your defense.

Ongoing Communication

You'll never wonder where your case stands. We keep you informed at every step, answer your questions promptly, and make sure you always feel prepared for what comes next.

Post-Case Record Relief

A favorable outcome is just the beginning. We also assist clients with expungements and record sealing so a past charge doesn't follow you into the future. You deserve a clean slate.

Why a the Right Criminal Defense Firm Matters

✓ Your Freedom Is on the Line

Criminal convictions carry fines, probation, jail, and a permanent record that affects employment, housing, and your future. You need a lawyer whose entire practice is built around beating these outcomes.

✓ Texas Prosecutors Are Specialized. So Are We.

The Dallas County District Attorney’s Office assigns DWI, drug, and violent crime cases to experienced prosecutors. A generalist attorney is outmatched. Spangler Law knows these prosecutors, these courts, and these tactics.

✓ We Convert Cases Others Give Up On

Our 850+ dismissals include cases that initially seemed like certain convictions. From DWI with a high BAC to serious felony charges, we find angles that other attorneys miss.

✓ Reach Us Day or Night

Arrests don’t happen on business hours. Spangler Law is available 24/7 for new clients. When you call, you’ll speak with someone who can actually help — right away.
