About Dianne
Ms. Sullivan earned her B.A. in Social and Behavioral Sciences from Seton Hall University in South Orange, New Jersey, graduating cum laude with a minor in criminal justice. She received her law degree from the Arizona State University College of Law.
Early in her legal career, Ms. Sullivan was Assistant City Prosecutor with the Office of the Phoenix City Prosecutor and, thereafter, a defense attorney with the Maricopa County Public Defender’s Office. At Sullivan Law Office, this very capable trial attorney handled all types of criminal law cases.
Arizona Divorce and Family Law
In family matters that are often intensely challenging and emotional for clients, Ms. Sullivan maintains the highest degree of professionalism in advocating on her clients’ behalf. Her cases include divorce, legal separation, annulment, child custody and parenting time, visitation, paternity establishment, complex property division, spousal maintenance, child support, custody modification, and other post-decree matters.
A spirited volunteer, Ms. Sullivan received the Pro Bono Services Award from Seton Hall University. In Arizona, she participates in the Volunteer Lawyers program which provides free legal services to qualifying individuals needing divorce and custody assistance, provides free estate planning for law enforcement and first responder personnel through the Wills for Heroes Program, and volunteers her time to assist veterans in need each year at the Veteran’s Stand Down.
