PLACERVILLE — Retired John D’Agostini has formally endorsed Sean M. Coppola in the upcoming June 2, 2026 election for El Dorado County Treasurer-Tax Collector, adding a high-profile local name to Coppola’s campaign as ballots are set to be mailed May 4.
D’Agostini, who served three terms as El Dorado County Sheriff-Coroner-Public Administrator from 2011 until his retirement on Dec. 31, 2022, praised Coppola’s financial expertise and understanding of county operations.
“I am extremely proud to have the endorsement of retired El Dorado County Sheriff John D’Agostini. Thank you, John, for your support and your continued commitment to our County,”

D’Agostini added:
“Sean is the right person for the job. He has the experience and understands the intricacies and importance of the County’s portfolio and how it is a multiplier of your hard-earned tax dollars.”
A Well-Known Local Figure
D’Agostini is a fourth-generation El Dorado County resident whose tenure as sheriff was marked by agency modernization and capital expansion. Before his election as sheriff, he spent nearly 30 years in law enforcement, beginning his career in 1993 with the Amador County Sheriff’s Office.
His most visible legacy is the $68 million Public Safety Facility in Placerville, completed in 2019 and later renamed in his honor in August 2023 as the John D’Agostini Public Safety Facility. The complex consolidated previously scattered operations into a centralized headquarters.
D’Agostini also established the department’s guiding principle,
“A Modern Approach to Traditional Law Enforcement Values,”
emphasizing both crime enforcement and victim care. Since retiring, he has remained active in public policy discussions and community initiatives.
Coppola’s Background and Campaign
Coppola was appointed Treasurer-Tax Collector by the El Dorado County Board of Supervisors in December 2025 to fill the unexpired term of retiring Treasurer Karen Coleman. His term began Dec. 27, 2025, and runs through Jan. 2, 2027. He is now seeking a full four-year term in the June 2026 election.
Prior to his appointment, Coppola served approximately two years as assistant treasurer-tax collector. He holds a bachelor’s degree in finance from the University of Nevada, Reno, and is a Certified Treasury Professional. Before entering county government, he worked as an accountant and controller for a Folsom-based property management firm.
As Treasurer-Tax Collector, Coppola oversees county banking, investments, property and business tax collections, and licensing functions. The office manages an investment pool of roughly $1.1 billion in public funds, according to county documents.
In recent months, Coppola has hosted community meet-and-greet events, including a February gathering at Moonraker Millhouse, to discuss fiscal priorities and modernization efforts. His platform emphasizes continuity, fiscal integrity and expanded technology services, including online billing systems aimed at improving efficiency for residents.
Election Timeline
Ballots for the June 2, 2026 election will be mailed beginning May 4. The Treasurer-Tax Collector position is countywide and oversees core financial operations affecting public services, infrastructure funding and tax administration throughout El Dorado County.
D’Agostini’s endorsement comes as candidates work to secure voter support ahead of the primary. With financial oversight and taxpayer dollars at stake, the race is expected to draw attention from voters focused on fiscal stewardship and government accountability.
