      Brett and his team were beyond supportive, helpful, gracious, caring and knowledgeable! We went through the most challenging and difficult time in our life and he was there every step of the way. With results we could never have imagined but definitely prayed for.

      Not to mention his level of professionalism. From the first time we spoke to the first time we saw him in court. He stood out from almost every other attorney there. We were so appreciative that our attorney looked and was so professional, pulled together and prepared. When so many others were none of these things.

      Thank you just doesn’t seem like enough to convey our feelings and appreciation.

      I tried to write this several times and it brought me to tears. First may I say this has been the hardest three years of my life. Five lawyers I interviewed and none even understood the law as it applied to my case. So I thought I would try one more and it was Brett. From our first conversation together I knew he understood the law and was the perfect one for the case. I want to say how he prepared the case and presented it, achieving a full dismissal and ruling the police violated my first amendment rights. Complete genius!!!!

      If you're reading this review and unsure, stop...call Brett. He always returned my call or texts within a couple hours, never more than 24 hours. He was always courteous and knowledgeable, trust me he talked me off the ledge a couple times. I would have given him 10 stars but 5 was the only option. Thank you Brett for all you did for me!!!!!

      Astigmatism and HGN Test Results for DUI

      Can Astigmatism affect HGN test results for DUI?

      Yes. According to the AOA (American Optometric Association), nearsightedness/astigmatism/poor eye muscle development may also cause nystagmus.

      What is Nystagmus?

      In short, Nystagmus is a condition that affects the eye muscles. The eyes make repetitive, uncontrolled movements. This condition impairs an individual’s ability to interpret depth, reduce visual acuity, and can sometimes affect balance and coordination.

      Nystagmus is generally a symptom of some underlying medical or physical problem. It can be made worse by fatigue and stress (as occurs with every DUI stop). When it occurs in adults, it is usually the result of a problem in the central nervous system (CNS), a metabolic disorder, or impairment due to drugs or alcohol.

      Acquired nystagmus is present in adults. It can be the result of an underlying neurological condition or other problems such as:

      • Stroke
      • Conditions impact the CNS (central nervous system)
      • Multiple sclerosis
      • Nearsightedness
      • Astigmatism
      • Cataracts
      • Inner ear inflammation
      • Anti-epilepsy drugs

      Among the causes of nystagmus is drug- or alcohol-induced inebriation. But intoxication is only one of many possible causes of this condition. Unfortunately, this test is often used to build a case against drivers who may not actually be impaired.

      If you have been arrested for DUI and field sobriety test results are being used against you, don’t face the legal system alone.

      Client Reviews

      Brett provided exceptional legal support during a very stressful time. He was professional, knowledgeable, and easy to communicate with throughout the entire process. His associate Kayla was also fantastic—always responsive and patient in answering all my questions. I truly felt supported and well-represented. I highly recommend their team for anyone needing DUI legal assistance.
