Dianne Sullivan

Dianne first began her law career in the City Prosecutors office, in Phoenix as an assistant prosecuting attorney. While serving the city, she successfully prosecuted domestic violence offenders, along with DUI and other misdemeanor cases.
After leaving the prosecutor’s office, she worked in criminal law, as well serving the needs of the County Public Defender’s Office but family law is where she found her calling. To help families in need of compassionate counsel. While working for large family law firms, she found the lack of personalized service to be a product of the corporate environment, which placed profits over people. So, branching out on her own, she opened Sullivan Law Office, a small boutique law firm which prides itself on the compassion it shows to every family that walks through the door. It’s important to Dianne that each client will know their family is important and more than just a case because she truly cares about the positive outcome of each and every family she serves.

Sullivan Law Office now handles every type of Family Law case, including divorce, child support, child custody, parenting plans, spousal maintenance, paternity, mediation, evaluations and appeals.
