"Mr. Dau regularly takes on and wins cases that, on the surface, seem to be long shots. I have no doubt that his success is attributable to his talent, work ethic and ability to pick a jury and win at trial. He consistently outworks and outsmarts the other side. If I ever need an attorney, he will be my first and only call."
"I met Tristan in my San Antonio office when he stopped by to visit while he was a student at St. Mary's Law School. Tristan was in his third year and contacted me due to our connection as former Austin Police officers. I was impressed at that meeting to the point that I offered Tristan a job that day. Tristan finished his third year and came to work for with a Third Year Bar Card under my supervision. Tristan is a quick learner and it was a pleasure teaching him the "Dude's" methods. I didn't waste any time putting Tristan in the courtroom trying cases and he has meet the high goals I set for him. He did that because he sets the highest goals possible for our clients. Tristan and I have tried a number of cases together and he also tries them without me. I am talking about difficult fact scenarios in tough jurisdictions against the odds and Tristan has gotten wonderful results for our clients. Tristan has a great future with my firm and I endorse him with confidence. - the DWI Dude"
