Raised in Staten Island as the oldest of three sisters, DiMaso graduated from St. John's University, earning a bachelor of science degree with a major in management, and was awarded a juris doctor degree from St. John's University School of Law in 1987. She moved to Holmdel with her family in 1993. DiMaso graduated in 2004 from the Christine Todd Whitman Excellence in Public Service Series, a program designed to foster public service by women. From 2002 to 2012, DiMaso served on the Holmdel Township Committee and was chosen by her peers to serve as the township's mayor from 2006 to 2010. She served on the Monmouth CountyBoard of Chosen Freeholders from 2012 to 2018. On the Holmdel Township Committee, DiMaso was an advocate for open space preservation and shared services, serving as a representative on the township's planning board, as chair of the Public Safety and Administration committee and co-chair of the Public Works committee.
DiMaso first took office as a Monmouth County Freeholder on January 14, 2012, when she was appointed to fill the seat vacated by Robert D. Clifton when he took office in the General Assembly. She was elected to full three-year terms in 2013 and 2016, and was chosen by her peers to serve as the board's deputy director for three one-year terms. As a freeholder through 2016, DiMaso received healthcare benefits from the county, paying $66,000 for four years of coverage, despite a policy that had been established by the county that prohibited officials from receiving coverage unless they were full-time employees; she was the only freeholder to have received health benefits from the county. She was elected to her first full term in 2013 together with Arnone, defeating Democrats Brian Froelich and Larry Luttell. In a tighter race in 2016, DiMaso and Arnone were re-elected as part of the Republican sweep of countywide elected offices, defeating Democratic challengers Matt Doherty and Sue Fulton ; Democrats had focused on DiMaso's healthcare coverage and a 2015 tax increase, while Republicans pointed to corresponding tax cuts in 2016.
With Declan O'Scanlon running for Senate to fill the seat vacated by fellow Republican Joseph Kyrillos, DiMaso was chosen to run for O'Scanlon's Assemby seat. In the November 2017 general election, DiMaso and her running mate, incumbent Amy Handlin, defeated Democratic challengers Tom Giaimo and Mariel DiDato to win both Assembly seats from the district for the Republicans. DiMaso serves in the Assembly on the Education Committee; the Human Services Committee; and the Law and Public Safety Committee. In July 2018 fellow Assemblyman Eric Houghtaling and fellow Assemblywoman Joann Downey filed a complaint against DiMaso for violating the truth Truth-In-Caller ID act.
