The BEST result I could hope for....closed and DISMISSED! He is very well respected amongst his colleagues as well as all the judicial system.

Types of Assault Charges

In the state of Texas, the scope of cases covers a wide variety of offenses, sometimes pertaining to self-defense, prohibited weapons, armed robbery, DWI, and sex crimes. Regardless of the context, it is important that you seek the help of a lawyer right away. When you have been charged by another party, the state will proceed even if the other party changes their mind and “drops” the charges. A criminal defense attorney can help you mount a defense immediately to protect your best interests.

Mr. Trumpler has represented clients in Austin, Travis County, and throughout Texas who have been involved in a wide variety of offenses, including: 


Assault is one of the most common charges we see at our Austin, TX, law firm. If you intentionally or recklessly caused another person or a spouse's bodily harm, you can be charged. This charge also includes threats of bodily injury or physical contact that are perceived as offensive or provocative.

Aggravated Assault

This offense is usually brought against a defendant if their actions result in serious injury or if a weapon was used during the incident.  This offense is another common charge seen at our Austin law firm. 

Assault Involving Family Violence

Domestic violence is a threat or act of violence that causes bodily harm to another person in a domestic situation. In cases involving domestic violence, our lawyer understands that there are two sides to every story. If you acted in self-defense or did not commit violence at all, Mr. Trumpler can tell your side of the story to help you clear your name.

Intoxication Assault

Per Texas's Penal Code § 49.07, intoxication assault occurs when a person accidentally causes serious bodily injury to another person while they are intoxicated and operating an aircraft, amusement ride, or vehicle. Driving while intoxicated (DWI) is a very serious accusation, but Mr. Trumpler has helped many clients charged with DWI have their charges dismissed or reduced. If you are facing a DWI conviction, Mr. Trumpler can also help you as a DWI attorney.


Deadly Conduct

Under Texas's Penal Code § 22.05, a defendant can be charged with deadly conduct if they engage in activity that places another person or spouse in imminent danger of a serious injury or if the defendant fires a deadly weapon in the direction of another party. While the first scenario is a Class A misdemeanor, the second is a felony in the third degree.

Terroristic Threat

Under Texas's Penal Code § 22.07, a terroristic threat is defined as a threat of violence towards a person or property that is designed to cause a reaction from emergency personnel or agencies, make others believe that they are in serious danger of bodily injury, and other similar situations.

Deadly Force in Defense of Person

There are some situations in which deadly force against another person or party is warranted. Per Texas Penal Code 9.32, deadly force may be necessary when an individual feels that there is a threat of unlawful deadly force against them or if they are preventing the other person from committing kidnap, murder, sex crimes, or robbery.

Deadly Force to Protect Property

If you had to use force to protect your property from trespassers or unlawful interference, the law is also on your side. Texas law protects people who had no other choice but to use force to prevent trespassing, arson, burglary, and other criminal actions.

Sexual Assault

Sex crimes or sexual assault include unwanted or involuntary sexual contact from one party against another through force, coercion, or if the alleged victim was incapacitated. Sometimes, sex crime accusations can be made against innocent people due to a variety of reasons, such as mistaken identity, revenge, or even regret. Sex assault convictions can have a devastating impact on the rest of your life, affecting your job, school, and even living arrangements.

Attorney Jason Trumpler with associate
Now I have not been in this situation before so while I don't have much to compare this experience to, I URGE that you read this if you are in a situation that was similar to mine, and are in desperate need of an attorney to represent you.

I was given a very serious charge that would've devastated my future. Jason was super professional and treated me with the utmost respect through the entire process. He was also very honest about the nature of the situation and that the charges would potentially have implications on my future. We explored the different opportunities of the situation and I ultimately allowed Jason to handle the situation in the way that he saw proper.

This resulted in my charges being dropped.

Get Jason, he makes for a great lawyer who really cares about you and your future.
