DUI and Drug Charges Lawyers in North Texas
When charged with a DWI / DUI or other serious traffic offences, you face significant penalties in criminal court and even loss of your drivers license. This is why it is important to secure the representation of a lawyer protecting your rights and interests.
Controlled substances are illegal. If you are found trafficking or in possession of illegal drugs such as heroin, amphetamines and cocaine, knowingly or unknowingly, you can be charged with a drug offence. Carrying more cannabis than the legal limit can land you in trouble.

Plain English
What good is legal service if you don’t understand the approach? The law can seem like a foreign language, especially to those with little or no previous experience of it. Our goal is to explain your options in a clear and concise way and to ensure that you have the representation you deserve, that your rights are protected, and that when your case is over, you are satisfied. You will be informed of each step of the legal process and kept up-to-date on the status of your case. All options available to you will be presented in a clear, easy to understand manner so that you make informed decisions on how your case should proceed.
Our Approach
No two clients are the same, and every client deserves the utmost in personalized service. Whether this means incorporating flexible billing, negotiating out-of-court remedies, or seeking non-legal solutions, we take the time to sit down with each client, truly listen to their story and their needs, and then tailor our approach so that it best meets those needs.
Open pricing means you’ll never be surprised by a bill again. It means that we can have a discussion without the meter running. It means you’ll pay a price that reflects the value of our services to you, not the number of hours we can bill. Simply put, open pricing means that we agree on a price up front, I do whatever it takes to resolve your matter, and you pay the price we agreed upon. Easy, right?
