Houston’s ACS/CHAL Forensic Lawyer Scientist
When Your Lawyer Is The Highest Qualified Expert Witness, You Gain an Edge.
Houston DWI defense attorney Tad Nelson, our law firm’s leader and founder, is one of a small group of DWI lawyers who are certified ACS/CHAL scientists.
What Does “DWI Lawyer Scientist” Mean?

It means that your lawyer, assuming that you’ve met with one of the DWI attorneys of Tad Nelson & Associates and subsequently secured legal representation, is qualified to teach the science of biochemistry as it relates to the effects of alcohol on human physiology, or the lack thereof.
In other words; your lawyer, assuming that you’ve met with attorney Tad Nelson or an associate attorney of the law firm, will likely be the most educated, competent, and best trained professional in the courtroom as it relates to the nuances of your case.
Being represented by a lawyer/scientist can also be construed to mean that your lawyer has the knowledge and credentials to immediately discredit any “so-called” expert witness, who may testify on behalf of the District Attorney during a trial related to DWI offenses, on the spot in an official capacity.
Importance of Representation By an ACS/CHAL Lawyer-Scientist
Aside from being certified a lawyer/scientist as a result of successful completion of the ACS (American Chemical Society) Hands-On Forensic Chromatography Course, being one of the foremost leaders in the field requires an intense knowledge of the alcohol detection technology law enforcement has at their disposal.
It must also be taken to mean that The Law Offices of Tad Nelson & Associates will be able to certify, or decertify equipment like the Intoxilyzer based on the standards of technological maintenance, upkeep, and administration of these tools.
Understanding The Nelson Firm Culture
When you walk into any of our law offices, you’ll be met at the door with the essence of professionalism, attention to detail, and an unparalleled sense of family. We care about our clients and our reputation.
The success of our attorney-client partnerships directly relates to our reputation.
We spare no effort when it comes to ensuring that all Nelson Firm lawyers are above the median when it comes to their skill-set and credentials as it relates to defense litigation involving accusations that one of our clients operated a vehicle while intoxicated.
If you’ve been accused of drunk driving, or are facing trial for any criminal offense solely based on your “alleged” biochemistry, you need to contact us.
Regardless of how convincing the State’s case against you may seem, police officers aren’t chemists, they aren’t medical doctors, they aren’t Board Certified in criminal law, litigation, procedure, and most of the time, neither is the prosecutor.

Thank you Tad Nelson for standing up for me and what is right, Tad Nelson is obviously well known and respected through out the court system as he spoke with authority and precisely to the assistant DA resulting in the dismissal of my case before the case went to trial. Thank you again. if you want it done call Tad Nelson
I hired them a while back for a DWI out in Harris County, they're good and if you need help with any kind of legal matter, give em a call. For a lawyer, Tad has a great personality so working with him should be easier than working with other lawyers.
He is the one lawyer that I can call and put my trust into. We’ve used him a couple of times, once for a family matter and another time for a troubled relative. He’ll help, tell you the truth with no sugar-coating, and will work for his salt. He’s a good guy and when you go to their office, they make you feel at home, like you’re part of the team. Good lawyers and great folks.
I've had the pleasure of working with Tad personally as a technology consultant for him in the past. We've eaten lunch and dinner together. I know that Tad is very dedicated to his clients and cares for them off the clock. He's definitely the lawyer you want on your side.
