Governor Murphy Announces Departure of Chief of Staff Diane Gutierrez-Scaccetti and Names Tim Hillmann as New Chief of Staff

Today, Governor Phil Murphy announced that his Chief of Staff Diane Gutierrez-Scaccetti will transition to a new role as a senior advisor to the Governor. Tim Hillmann, currently serving as the Governor’s Principal Deputy Chief of Staff, will assume the role of Chief of Staff later this summer.

“Diane Gutierrez-Scaccetti has done an outstanding job as my Chief of Staff over the past year,” said Governor Murphy. “From negotiating a reauthorization of the Transportation Trust Fund to successfully enacting a Fiscal Year 2025 budget with our partners in the Legislature, Diane has brought a wealth of knowledge, experience, and expertise to our team. I’ve asked her to continue serving our Administration as a senior advisor to help troubleshoot some of our most pressing and challenging operational challenges – such as large-scale infrastructure projects and complex interdepartmental initiatives. I thank Diane for her service as Chief of Staff and look forward to her continuing to play a senior role on my team.” 

“Tim has been a key member of my team since 2019 and has successfully overseen our legislative affairs, intergovernmental affairs, appointments, and constituent relations teams, among other departments,” continued Governor Murphy. “I am excited to have him lead our team in the Governor’s Office and advance our mission of building a stronger, fairer, and more affordable New Jersey.”

Gutierrez-Scaccetti came to the role as the Governor’s Chief of Staff with over 40 years of experience in public service. She spent 21 years at the New Jersey Turnpike Authority, where she rose in the ranks from Contract Administrator to Executive Director. During her tenure, she oversaw administrative operations, led negotiations with collective bargaining units, and played key roles in initiatives such as E-ZPass System remediation and the consolidation of the New Jersey Turnpike Authority and New Jersey Highway Authority.

Tim Hillmann has served as the Governor’s Principal Deputy Chief of Staff since October 2023. Prior to his current role, he served as Deputy Chief of Staff for Government Affairs and as the Governor’s Director of Appointments since 2019. Before that, he spent nine years working in the United States Senate.
