Tony Sun – Criminal Defense Attorney

One night in college, my best friend was the designated driver for our group of friends when we went downtown Austin. At the end of the night, he drove us back as planned. But on the way back, a police officer stopped us. None of us had any clue why. My friend wasn’t drunk, and his driving was perfectly safe. But, as luck would have it, he ended up getting arrested for a DWI.

That summer, he had a prestigious internship lined up with a research institute. However, because of his arrest, they told him that he could no longer participate. So my friend hired a lawyer to defend him. After several months, sure enough, his DWI charge got reduced to a Parking in a No Parking Zone.

I saw firsthand how powerful having an effective advocate and a clean record had on his life. He ended up getting into a top graduate school to study biomedical engineering in California, where he later met his wife. And that is why I defend people. Because I get to help people get their future back.

Austin's Finest - 5 Star Reviews


Mr. Sun's passion for his clients and knowledge to represent them fully is nearly unmatched. He will consistently go the extra mile for you. Can't recommend highly enough.


This was my first court visit. Tony made sure we had everything ready in advance and did a great job of communicating with me. He showed up prepared and ready to fight the case. Thanks to him, I won today! I highly recommend him as an attorney.


Tony really understands his client's needs. I have had the honor of having Tony as my criminal defense attorney, and I must say he has been by far the most personable, professional, and caring lawyer I've ever had. Tony services expunctions and get-out-of-jail specialties, and I had the privilege of having him represent me in a court trial for a traffic offense that he won for me (of course). I would heavily recommend Tony Sun for all your legal action needs.

Practice Areas

  • DWI

    The primary focus of our Austin Law Firm is DWI Defense. When you're going up against the State of Texas, they want to punish you and fine you as much as possible. My goal as your lawyer is get the state to dismiss your DWI and to reduce the fines and punishment as much as possible. So you can get back to your life without a DWI conviction on your record.

  • Expunctions

    Expunction is a guaranteed legal right of everyone who gets a case dismissed in the State of Texas. The main benefit of an expunction is being granted the right to truthfully deny you were ever arrested for the offense to future employers, landlords, and colleges.
