  • Stephen Robert Baxley

    I endorse this lawyer. I have known Gary since I began work as a baby prosecutor in 1998. As a prosecutor, I only lost 2 DWI trial. One was to Gary and working against him was great training for later when I saw the light and began defending people. When I practiced in Houston, Gary was on the short list of folks to call with any legal question or strategy on a case. He is a wonderful lawyer, great guy, and I endorse him with no reservation.
