You can look the attorney up here, but also on the Arizona disciplinary website. Here http://www.azbar.org/lawyerconcerns/disciplineprocess/reportsoflawyerdiscipline
You could also call them and ask.
Understand, the only way you can know if an attorney has been disciplined is if that discipline was public. It is possible for an attorney to receive private discipline in most states (I don't know about Arizona.) If that is the case, you wouldn't be able to find out very easily.
