Born and raised in Atascadero, CA, Seth pursued his lifelong dream of becoming a firefighter at a young age.

His leadership included overseeing emergency operations, managing budgets, and coordinating large-scale fire response efforts.

Throughout his career, Seth has attended numerous training courses and earned multiple certifications, including the Governor’s Award. His expertise ranges from supervising wildland fire divisions of 100 firefighters to preparing and managing fire department budgets.
