Jump to navigation By 02/03/2021 After a quarter of a century and only one contested election, Marin County Sheriff Robert Doyle will retire from his post in 2022. The race for the seat has begun: Undersheriff Jamie Scardina, who was endorsed by the sheriff after two decades with the county department, announced his run against newcomer Adam McGill, the city manager of Novato. This week, the Light spoke with Undersheriff Scardina. The 45-year-old Marinwood resident and father of two has spent nearly his entire career rising in the ranks of the Marin County Sheriff’s Office after getting his start with the Tiburon Police Department.
