Collated independently by Legal 500 research team.

  • ‘Our experience was working directly with Greg Casas, in the Austin office. His experience, creative and thoughtful interpretations of situations were not only relevant, but compelling. The research team and their diligence was incredible and the diversity of individuals he has on hand as expert witnesses was exceptional.’

He presents an honest interpretation, but is not afraid to play hard to shed his case in a winning light and spin the favorable points admirably.’
