Gregg Jarvies, 46, has served the Chapel Hill Police Department for 25 years and was sworn in by Mayor Rosemary Waldorf during the 2 p.m. ceremony Tuesday.
He became interim police chief in April 2000, after Chief Ralph Pendergraph retired.
With his family in the front row, Jarvies spoke about what it means to be one of Chapel Hill's finest.
"It is special to be an officer in Chapel Hill," he said.
"Our primary responsibility is to treat everyone fairly."
Jarvies also complimented his staff of officers as outstanding employees.
The public ceremony was attended by Town Manager Cal Horton, former Police Chiefs Ralph Pendergraph and Arnold Gold, various Chapel Hill police officers and other members of the Chapel Hill Police Department.
Jarvies said he is looking forward to the challenges ahead and named town growth as the primary challenge for the police department.
"The biggest challenge will not only be to build on what's been left, but also to grow," he said.
