Case Dismissed!
Dianne represented me in a criminal case where I was unjustly charged with custodial interference. She lobbied hard on my behalf and got my case dismissed. Due to my profession, a conviction would have resulted in me losing my job. I could not be happier with her work on my case.

Experience
Professional misconduct
This lawyer was disciplined by a state licensing authority in 2017.
Admonition and Probation issued in AZ, 2017
updated on 08/09/2020An admonishment means the attorney did something wrong but may still practice law. While on probation, the State monitors the attorney's activities for a period of time in hopes that he or she will not repeat the behavior.
Dianne’s comment:
“An admonition is the lowest and most informal sanction the bar imposes. A former client who chose not to follow my advice was later sanctioned by the Court for her conduct. She filed a complaint, alleging I advised her to violate the Court's orders. While this allegation was not true, I should have withdrawn from the case rather than continue to advocate for this client and her children, and therefore chose to accept the bar's decision to issue an admonishion.”
