Our firm utilizes TexasDWIExpert as our “go-to” resource for expert review of  field sobriety tests, DWI investigation procedures, and for expert testimony at trial.  Our clients benefit immensely and we have achieved extraordinary results because of the assistance of Lisa Martin and her firm.

For example, recently, based on part of the assistance we received from TexasDWIExpert, we had a client who was originally arrested for Intoxication Assault.  Based on the exemplary work of our team of attorneys and the help of Ms. Martin, we were able to achieve a reduction in charge from that of the original arrested offense to a 12-month probation for Obstruction of a Highway or Other Passageway (a Class B Misdemeanor).  

We consider Lisa and TexasDWIExpert a valuable member of our team in our quest to attain the best possible results for our clients.

Lisa did a great job working for us. She was very timely and is very intelligent. She dissected everything the DPS officers did and provided a great report. She learned there were several mistakes the DPS officers made during every SFST that was administered. The result from her report was very favorable for our client. Her report was a big reason that our clients charge was reduced to obstruction. We look forward to working with Lisa in the future on any DWI cases that we take to trial. Highly recommend!

I am happy to tell anyone that wants to listen how helpful and worthwhile Lisa’s reports are. She has saved me hours of work plus her detailed discussion will make a cross a cakewalk. I look forward to my next case with her. Thank you again for such a wonderful detailed, well-explained job.

Can’t Say Enough Good Things

In the world of DWI expert witnesses, there are those that are academically qualified and those who aren’t! Indeed, among those who are qualified, there are those that can communicate, but sadly, most can’t! Narrowing the “can” pool, there are even fewer that are both natural and likable. Enter DWI Standardized Field Sobriety Test (SFST) Expert Lisa Martin!

As 1 of only 5 DWI Specialists in Texas who are allowed by the Texas Board of Legal Specialization to say we are “Board Certified Experts”, I can say that SFST Expert Lisa Martin is amazing. Not only has she taught and explained to me more about those field sobriety tests than I did know, but more, she has both made me a better lawyer and a more effective advocate for my DWI & ALR clients. Lisa is quick to recognize offense report and audio/video recording issues. Once identified, she has the witness talent to credibly weave and teach those reasonable doubts, in lay terms, to your jury. Alternatively, you can use those evidence points in your cross-examination of the arresting officer. Further, because she is an excellent writer, her opinion reports can be offered in ALR cases as impeachment evidence describing why the officer’s SFST “clues” should be suppressed, doubted, or given little weight!

With the above in mind, remembering the old saying, “it takes one to know one”, I have no hesitation in sharing my opinion that Lisa is an Expert’s Expert! Moreover, based on my experience in the world of DWI experts, she is the Best of the Best in SFSTs!! That said, I highly recommend Lisa to you as a defense tool and as a resource for your DWI defense practice. Unquestionably, you want her on your team!!!

I have had the pleasure of retaining and working with Lisa as an expert on numerous DWI cases. Her expertise in the administration of the Standardized Field Sobriety Tests, as well as her ability to relate and explain her findings, and the intricacies of this testing, to a Judge and Jury is beyond comparison. She has an outstanding courtroom demeanor and is an outstanding witness. I have had many cases where her successful testimony during a suppression hearing resulted in it the suppression of the evidence or ultimate dismissal of the case. The State will most certainly have DRE experts to testify in an attempt to justify any shortcomings in the officer’s administration of the SFST. As a result, I cannot emphasize enough, the importance of hiring Lisa, as a defense expert, to explain how the SFST should be administered and the methodology behind this testing. Lisa is extremely thorough, exceptionally knowledgeable, and very punctual in reviewing the evidence and getting back to you with her findings. The report she issues in every case is a must-have not only for suppression hearings, and trial, but also for the ALR hearings. Lisa is outstanding, and a must-hire in any DWI case where your client submitted to the SFST’s.
