David I.

Seguin, Texas

Brad was great from the moment he looked at my case. Despite his busy schedule, he made himself easily available, walked us through every detail with care and professionalism, and worked out a great deal with the prosecutor that was much better than any outcome we could have imagined. I don’t plan on needing his assistance again, but if I’m ever unfortunate enough to find myself in another legal bind, Brad will be my first call.

Brian F. 

San Antonio, Texas

I have had the opportunity to know Brad both personally and professionally for a while now. As a fellow attorney, I am consistently impressed by his passion and innovative approach to legal issues. He is exceptionally intelligent and is always willing to go above and beyond for his clients. When I refer clients to Brad, I have full confidence that they will receive top-quality representation.

Elaine B.

San Antonio, Texas

Brad is an amazing attorney, and I highly recommend him! He has deep knowledge and understanding how to navigate the law to support his clients. He has a way with people, and truly has his focus on client care and supporting them, during a time that’s usually stressful for clients. He was able to support in getting my case dismissed in less than 2 months and was attentive and personable during the whole process. You have a choice when deciding who’s going to represent you, and to have an attorney that genuinely cares for his clients should be an expectation anyone should set. Brad will meet that expectation 110%!

Kevin E.

Jourdanton, Texas

[Brad] made the process very easy for me, handling everything within a month, with a motion to dismiss all cases against me. I only had to attend court once! The portal he uses to make sure you are aware of everything going on in your case is awesome, I didn’t even have to worry everything got downloaded to the portal with email notifications. I would never use another attorney to represent me, he is the best at what he does.
