Sierra Vista hospital set for $220 million expansion
Sierra Vista serves as San Luis Obispo County’s only trauma center
– Adventist Health announced Saturday the approval of a $220 million capital expansion at Adventist Health Sierra Vista, marking one of the most significant healthcare investments ever made in San Luis Obispo County.
The investment will modernize and expand facilities at Adventist Health Sierra Vista to strengthen access to care and support the delivery of complex and specialized services locally. Project planning is underway, with groundbreaking and the start of construction anticipated in 2028.
Planned improvements include a new emergency department and trauma center, new labor and delivery and postpartum units, new operating and procedure rooms to support expanded services, a new intensive care unit, and remodeled inpatient rooms designed to enhance comfort, healing, and the overall patient experience.
“This investment reflects our long-term commitment to the Central Coast,” said Ryan Ashlock, president of the Adventist Health Central Coast Network. “From the beginning, we recognized that this community expects more from its healthcare providers — and that earning trust matters. This project ensures families can access the care they need in facilities that reflect the level of care already being delivered here.”
Adventist Health Sierra Vista serves as San Luis Obispo County’s only trauma center, only neonatal intensive care unit, and only pediatric inpatient unit, caring for patients during critical medical situations. The expansion is designed to increase capacity, support new technology, and expand services locally, reducing the need for patients to seek complex care outside the region.
The announcement was made during the San Luis Obispo Chamber of Commerce Annual Gala, where Adventist Health served as the presenting sponsor.
The Central Coast network operates two hospitals, two imaging centers, and a growing network of primary and specialty care clinics throughout San Luis Obispo County, providing healthcare services across the region.
“This is more than a construction project,” Ashlock said. “It’s a commitment to access and the future of healthcare for this region.”
