  • Allen Ross Blake

    Mr. Trumpler is a uniquely qualified defense attorney. He has the rare combination of a great legal mind and charismatic personality. He understands the nuances of the law and at the same time is able to personally relate to prosecutors, judges, and, most importantly, juries. I would recommend Jason Trumpler to anyone facing criminal charges in Central Texas.
