Criminal Defense Attorney

Whether you are in trouble with the law or your son or daughter has been charged with a juvenile crime, you need a lawyer who knows how to get results. I am McKinney criminal defense attorney Matthew Maddox. My law firm is focused exclusively on criminal defense for adults and juveniles accused of felony or misdemeanor crimes in Collin County, Texas, and the communities of McKinney, Plano, Frisco and Allen.

I am passionate about helping people who are struggling with issues that seemingly dominate their entire lives. I know what it's like to be in trouble, which is why I work to get you out of trouble as quickly as possible. Give me a call: 972-373-3635.

A Skilled Negotiator And Aggressive Litigator

I believe that the best attorneys know how to fight and when to do it. I am an experienced litigator who really enjoys advocating aggressively for my clients in court. But I'm also a skilled negotiator working early and behind the scenes to get you the best possible outcome as soon as possible.

My goal is to alleviate your stress and give you peace of mind. I always keep you well-informed of what you can expect to face, and what strategy I will use to fight criminal charges. Contact my office today.


I take your future and your freedom seriously. Trust in a criminal lawyer who will fight for the best result — trust in The Maddox Law Firm.

Safeguarding Your

Rights And Fighting For Your Freedom

One criminal conviction can derail your entire future. Even a minor criminal charge can have lasting consequences, and without an experienced defense attorney your rights may be infringed upon. I passionately represent clients facing a wide range of felony and misdemeanor criminal charges for:

  • DWI and drunk driving charges
  • Drug charges involving marijuana, heroin and other illegal substances
  • Theft crimes such as robbery or shoplifting
  • Violent crimes like assault, battery or domestic violence
  • Sex crimes

I also help my clients who qualify for it to secure an expungement to clear a criminal record or receive an order of non-disclosure to prevent others (like future employers) from seeing charges on their criminal record.

  • Juvenile drug crimes

You Have Questions, We Have Answers

The criminal justice system can be intimidating, and you may not know what to do next. Read our answers to some of the most frequently asked questions in Texas criminal law.

  • When do the police have to advise me of my rights?
    The police only have to issue a "Miranda" warning if you are both formally in custody and are being interrogated. It is crucial to understand these two points because the police can use anything you say against you — even before you have heard your rights — as long as these two conditions are not in place.
  • Is it okay to talk to the police if I am innocent of the charges?
    No. The best rule to follow when interacting with police is to remain silent until you have consulted with an experienced defense lawyer. Innocent people end up convicted all the time because of nervous mistakes they make when answering police questions. Something you say can be taken out of context. Something you forget to say can be seen as an evasion of the truth. Do not take chances with your future.
  • What is the difference between a misdemeanor and a felony?
    A misdemeanor is usually defined as a crime that is punishable by no more than a year in jail. Any crime that is punishable by a year or longer in prison is usually a felony. Generally speaking, there are many levels of both misdemeanor and felony charges and a broad array of possible punishments meant to fit the crime.
  • Is it possible to defend against a drunk driving charge if I fail the breathalyzer test?
    Absolutely. Breathalyzer tests are notoriously inaccurate and can be affected by everything from the way the machine was calibrated to whether or not you have recently taken some cold medicine. In addition, it is often possible to attack the basis, or "probable cause," of the traffic stop in the first place. No case is utterly hopeless.
  • I couldn’t be happier with my experience, they’re great friendly people who genuinely care and are super easy to work with!
