Posted by Barry | December 17, 2025 | Hired Attorney

Great attention to my health and my case.

I just wanted to point out that I have been very pleased with the attention received from the Garza employees concerning my case. Hayley has contacted me frequently to ask how I’m doing and how my progress is going. She, and Brent have been great from the moment I contacted them, and I recommend them... all the time to family and friends. Thanks so much for everything!

Posted by Mark | May 05, 2025 | Hired Attorney | Social Security Disability

Helping people with the initial process.

A few days ago, I started a Social Security disability claim with Garza law firm. My initial contact was with.Dailyn Clause . I’m completely unfamiliar with this process and really not electronically efficient. She basically has held my hand through this entire process and made it painless, and I nev...er felt as if I was inconveniencing her at any time. She’s been a godsend.

Posted by Pat | June 08, 2023 | Hired Attorney | DUI & DWI

Prized attorney

I was pulled over on Friday night and refused the breathalyzer. At that point I was taken to jail. Marcos was able to get me out of jail Saturday morning. If I had a lesser attorney I could have been there until Monday. That alone was worth every penny I paid him. At the final hearing I was able... to get the absolute best possible outcome and I give all the credit to Marcos. I am extremely grateful for the work of him and his team. I could not recommend him highly enough.

"Recently, I had the privilege of being a speaker with Marcos at a DUI conference in Tunica, Mississippi for several hundred lawyers. He absolutely won the audience over with his presentation, and lawyers are not an easy bunch to impress. I am certain that he is equally impressive in front of juries. Marcos has an outstanding reputation among his peers in the criminal defense bar, and is one of the leaders of the statewide association. Time and again, he is recognized for his excellence by his peers. If you are searching for a criminal defense attorney in Knoxville, Marcos Garza would be an excellent choice."

DUI and DWI lawyer | Oct 08

Relationship: Fellow lawyer in community

"Marcos is a fantastic criminal defense attorney but more specifically he is on the Dude's list of "go to" DWI attorneys when I am asked who to use in Tennessee when trouble lands. I met Marcos years ago while attending one of the top National DWI seminars put on by the National College of DUI Defense. Marcos immediately impressed me with his high level of knowledge, character and integrity. Marcos is highly respected across the nation as a top notch DWI Trial Attorney by those of us who practice in this area. Just because someone claims to be a DWI attorney does not make them the real deal. I have watched Marcos presenting at seminars and I have interacted with him personally. Marcos gives his very best efforts to protect and fight for his clients and that is a must in DWI defense. I am the DWI Dude out of Texas and I wholeheartedly endorse Marcos Garza as the DWI trial lawyer to help win your case, protect your good name and end your nightmare of a DWI arrest. Jamie "Dude" Balagia"

"I endorse this lawyer. I have known Mr. Garza for many years in the National College for DUI Defense. I have attended many seminars and lectures with Mr. Garza all over the country. Mr. Garza is one of the best DUI lawyers in the country and a better man and friend. Mr. Garza is an instructor at every level in DUI Defense from SFSTs, breath testing, and blood testing. I would not hesitate for a minute to recommend Mr. Garza for a family member or good friend who was arrested in Tenn."

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
