Jason Hill joined the Johnston Police and Johnston-Grimes Fire Departments as a Public Safety Support Specialist in June 2022. This new position was a budget priority in fiscal year 2023.

Jason's role will focus on providing technical assistance in network, technology, fleet technology, hardware, software, facilities maintenance, and automated process improvement.
