The Black and White Ball is a semiformal annual event that has raised funds for the John C. Fremont Hospital for over 30 years. We are grateful to our growing community for continuing to support the Healthcare District by attending this event.  

Your support of the John C. Fremont Hospital Foundation and the Black and White Ball for 2025 will provide needed financial support for Mariposa’s local hospital and its ever-expanding network of programs and services through the John C. Fremont Healthcare District. Beneficiaries served by the Foundation include: hospital and emergency care, outpatient services, and health education scholarships for youth and adults. 

Residents of Mariposa County, Yosemite National Park, and the rural communities surrounding the Healthcare District all benefit from your generous support.
