Tony Sun – Criminal Defense Attorney

10 years ago, my best friend was the designated driver when we went downtown. At the end of the night, he drove us back as planned. He stopped on the side of the road to drop off one of our friends. Immediately, a police officer pulled up behind 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 DWI.

The next week, my friend lost the prestigious job he had lined up after the company found out he was arrested. Everything he had worked for up to that point was in jeopardy. His future was on the line.

Another lawyer and I worked together to vigorously defend him. After several months of going back and forth with the prosecutors, we successfully reduced his DWI down to just a parking ticket. Now with a clean record in hand, he was able to get back on track and got accepted into a top graduate school, where he later met his wife and had a beautiful daughter.

After seeing my best friend go through this horrible process and having to worry about if he’ll ever get a good job again, I decided to dedicate my entire legal career to helping good people get their life back on track.

As a way of giving back, Tony frequently lectures at UT to pre-law students, he constantly releases new videos on his YouTube channel to empower Texans to know their rights, and has an avid love for dogsitting.

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.


Only had 2 attorneys my whole life and talked to over 40 attorneys to see what they were about and see which one I would rather go with. Tony Sun is reasonable in price and great in communication. He cares about his clients. Had my case dismissed in a couple of months. If looking for an attorney, Tony Sun should be your first and last call.


Best lawyer my son James has ever had. Tony knows what he’s doing and all the while he’s updating you on what could happen or will happen. He was not just an attorney in it for the money. He seriously cares about his clients as well as their well being. Very, very trustworthy. Thank you Tony for all you did for Q. There aren’t enough great comments I could say about you in my book. You will always have our respect and you were most definitely appreciated. Many blessings to you in your career. You are "Greatness in the making"


My name's Jack Keel and as a recently past client I'm here to say Mr. Tony Sun goes above and beyond to find any little reason to have a case dropped and facing some pretty serious time he basically found any little problem with my case that police made, got the deal he wanted which was a slap on the wrist (yes I've learned my lesson) I highly highly recommend Mr. Tony for any defense case bc he's affordable, keeps in touch and WINS!!!

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.
