Discipline status
We publish disciplinary status sourced from public State Bar of Texas records on every attorney profile. We display this transparently because clients deserve full information. Disciplinary history alone does not mean an attorney is unqualified — many attorneys with past discipline are competent practitioners — but it is information clients have a right to know when making a hiring decision.
