Nicole Brown, communications and engagement director for Prince William County, confirmed the transition in an email, indicating “Mr. Mancini resigned from Prince William County earlier this month, and the county is currently recruiting for the CIO position.” It is unclear whether an interim CIO has been named.
The county has posted an opening for a combined director of information technology and chief information officer, describing the role on LinkedIn as an opportunity for a “visionary leader” to provide “executive oversight of enterprise IT operations, cybersecurity, digital transformation, and strategic technology planning” across the organization.
Mancini’s departure closes a chapter of significant change in how the county approached technology. He oversaw efforts that ranged from modernizing legacy systems to strengthening the county’s cybersecurity posture, while also supporting population growth and meeting the demand for digital services.
During his tenure, which began in April 2017, Prince William County became a consistent presence in national surveys tracking digital maturity at the local level. He led the county to first place in the Center for Digital Government’s* 2023 Digital Counties Survey for its population class, after spearheading an overhaul of the jurisdiction’s technology, infrastructure and communications tools.
In 2024, Mancini was named one of Government Technology’s Top 25 Doers, Dreamers and Drivers list for his contributions to the county’s technology strategy.
Before joining Prince William County, Mancini served as chief technology officer for the government of the District of Columbia from 2011 to 2015, overseeing nearly 100 agencies, managing $150 million to $250 million in IT spending, and leading a staff of 550 technologists, according to his LinkedIn profile. Earlier, he served as deputy CTO and director of citywide messaging for D.C., where he helped modernize infrastructure, consolidate messaging and collaborative services, and manage a 400-mile fiber network.
The county is accepting applications for the director of information technology and CIO position through March 22.
