She attended college at the University of Nevada Reno and in 1989 graduated magna cum laude with a degree in Criminal Justice. In 1992 Judge Sullivan graduated in the top 20% of her class from the University of San Diego School of Law.
Judge Sullivan started her legal career at the litigation firm of what was then known as Jones, Jones Close & Brown (subsequently Jones Vargas). She practiced there for 12 years, becoming partner in 2001. In 2004 she left Jones Vargas and opened the firm of Ghanem & Sullivan, where she was managing partner until the firm closed at the end of 2008 upon her election to the Justice Court bench.
During her 17 years as a lawyer, Judge Sullivan was licensed to practice by the State Bar of Nevada, U.S. District Court of Nevada, 9th Circuit Court of Appeals, and Paiute Tribal Court. Judge Sullivan practiced in the areas of banking, business, real estate, and commercial landlord/tenant litigation, as well as acted as a private arbitrator. She served as Chair of the Clark County Bar Association Community Services Committee in 1997 during the year that the County Bar Association built a Habitat for Humanity home. She regularly provided pro bono representation for indigent litigants and mentored law students.
Since elected in 2009, Judge Sullivan has presided in Department 12 of the Las Vegas Justice Court handling both criminal and civil dockets. She speaks to and teaches at various discussion panels, training classes and seminars relative to matters within the Justice Court’s jurisdiction, and sits as a member on various committees within the court system. She participates in career forums in our public schools and is a mentor to at-risk high school students through the Clark County School District’s “Reclaim Your Future” Program. She judges moot court and mock trial competitions at both the high school and law school levels.
Judge Sullivan is married to Sean Sullivan – also a lawyer -- and they have 2 sons. They enjoy traveling as much as time and money will permit. She is an all-around sports fan, and aside from her family, her second passion is the San Diego Chargers.
