We Are Texas Trial Lawyers.

There is a difference between a litigator and a trial lawyer. Whether you are a plaintiff or defendant, you want lawyers who have had their mettle tested — lawyers who call the courtroom a second home and know how to win.

The business litigation attorneys at Deans & Lyons have tried cases for plaintiffs and defendants across the United States. We know how to prepare for the unexpected. No matter how complex your case may be, we have the experience and willingness to see it through to the end, and our opponents know that.

We are trial lawyers with the track record to prove it. Our motto isn't just a catchy saying—it's what we are:

Battle Tested. Razor Sharp.™
