Jason Trumpler

He Has Practiced
Over 20 Years

Since his career began in 2019, Jason Trumpler has worked as both a prosecutor and a defense attorney. He understands that many prosecutors' definition of victory doesn't always mean exposing the truth; rather, it's a matter of getting a conviction at any cost.

Mr. Trumpler knows how to counter these efforts in order to achieve justice on behalf of his clients.

He Is at
Your Service

Mr. Trumpler's office is reachable 24 hours a day, seven days a week. That means every time you call his office, you will speak to a human being.

And if he takes your case, you can expect constant communication that keeps you informed of the progress of your case and the next steps in your pursuit of justice.

His Rates
Are Affordable

Mr. Trumpler's clients can expect to pay $3,000 to $10,000 in attorney's fees, which is extremely reasonable compared to the rates other Austin-area firms charge.

However, be aware that cases involving serious felony charges can incur greater fees. Your freedom is priceless; fortunately, protecting that freedom doesn't have to leave you financially devastated once the case closes. 

Don't Take Chances With Your Future

An assault conviction can disrupt your life in ways that you may never overcome. Even a relatively short jail sentence can force you to carry a stigma for the rest of your life that will affect your employment prospects, personal relationships, and more.

Public defenders are notoriously overworked and won't likely have the resources to give your case the attention it needs. Meanwhile, Williamson County is no stranger to wrongful prosecution and conviction. Even under the leadership of a district attorney who has been outspoken about failures in the criminal justice system, you must understand that imperfections and prejudice permeate the court and could easily cause you to suffer consequences you don't deserve.

Jason Trumpler is an Austin-based attorney serving Round Rock and Williamson County who can give your case the scrutiny it needs in order to make sure you don't become a victim of injustice. All police reports, official statements, medical records, and other evidence will be analyzed by your criminal defense lawyer and his team for inconsistencies, misconduct, and other flaws that could make the difference between incarceration and freedom.

Mr. Trumpler has helped many defendants to achieve reduced or dropped assault charges; he can do the same for you. It all starts with a free case review. If you need a lawyer, you can send us a message or call us any time of day or night:

"I highly recommend Jason Trumpler if you need a great attorney and find yourself in a situation beyond your control. He kept me informed and worked very hard on my case and got it dismissed." Gustavus Chisholm, 5-Star Review, 2021

Assault Penalties

In Texas, assault is defined as intentionally, knowingly, or recklessly causing bodily injury to another person, threatening bodily injury, or causing physical contact that the perpetrator knows will be perceived as provocative or offensive.

An assault may be considered either a misdemeanor or a felony, depending on the nature and severity of the alleged crime. Here is a closer look at these two classifications and the penalties they carry in Texas:

Misdemeanor Assault

  • Class A Misdemeanor Assault: Class A involves physical injury. It can carry up to one year in prison and a maximum fine of $4,000.
  • Class B Misdemeanor Assault: This rare classification pertains to the assault of an athlete or coach by a spectator. Class B misdemeanor assault can carry maximum penalties of six months in jail and a fine of up to $2,000.
  • Class C Misdemeanor Assault: Assault involving offensive physical contact or the threat of injury (but not actually resulting in serious physical injury) is considered a Class C misdemeanor. Defendants face a maximum penalty of a $500 fine.

Felony Assault

  • First-Degree Felony Assault: A first-degree felony assault is characterized by aggravated assault (meaning it caused serious harm or involved a deadly weapon). It can carry a life sentence.
  • Second-Degree Felony Assault: Assault of a police officer, court judge, family member, or domestic partner is classified as a second-degree felony. This crime can carry a punishment of up to 20 years in prison and a $10,000 fine.
  • Third-Degree Felony Assault: This pertains to the assault of a government official, public servant, security officer, emergency medical technician, or pregnant person. It carries up to 10 years in prison and a $10,000 fine.

Mr. Trumpler's criminal defense services can result in dropped or reduced assault charges.

What If I Was Acting In Self-Defense?

Self-defense is the cornerstone of many criminal defense strategies in assault cases. Defendants can also claim to have been protecting others or their own property. However, no matter how clear-cut you may believe the circumstances of the incident are, Texas requires that you prove that you used the minimum amount of force possible in order to protect yourself or others.

You must also prove that there was physical violence or, at the very least, a threat of physical violence against you. In other words, if it can be demonstrated that the other party posed no threat or that you used excessive force, you may still face criminal penalties.

If you were acting in self-defense, criminal defense attorney Jason Trumpler can compile evidence to demonstrate to the courts that you were justified in taking action against the other party and that the amount of force used was reasonable for the purposes of protecting yourself and others.


DWI and Assault


If you are charged with driving while intoxicated (DWI) and injuring someone with your vehicle, it is considered intoxicated assault, which is a third-degree felony. Attorney Jason Trumpler, serving Greater Round Rock, Texas, has tried more than 100 DWI cases in Texas and California, helping many defendants to avoid suffering unjust penalties.

Although intoxicated assault is a serious crime deserving harsh punishment, the truth is that there are many flaws in law enforcement's methods of determining whether a driver is truly intoxicated. Mr. Trumpler is here to provide criminal defense services to clients throughout the Round Rock area, helping them to avoid bearing the consequences of faulty police work and other injustice.

Courtroom Victories For Clients Charged with Assault

Right now, it may seem like you don't stand a chance against the charges you face.

These are just a few instances in which clients facing seemingly insurmountable odds have achieved justice thanks to Mr. Trumpler's dedicated criminal defense services:
