Regina “Reggie” Marinelli for Jefferson County Sheriff


Reggie has worked for the Jefferson County Sheriff’s Office for more than 36 years and has held supervisory roles in every major division. She currently oversees hundreds of volunteers that are assigned to more than a dozen specialty units throughout the Jefferson County Sheriff’s Office .

Reggie is ready on day one to take charge and lead this agency. 

Reggie believes in a style of leadership that includes input from the community. With this style of management, she will build bridges with all First Responders and The Citizens of Jefferson County. 

As a 21st century law enforcement agency we must not settle or rely on the “way it’s always been.”  We must be willing to challenge the status quo, changing and evolving as needed to ensure efficiency and high-quality service.


“If you treat an individual as they are, they will stay as they are,

but if you treat them as if they were what they ought to be and could be,

they will become what they ought to be and could be.”
