STANFORD HEALTH CARE TRI-VALLEY LAUNCHES HOSPITAL EXPANSION

Stanford Health Care Tri-Valley celebrated groundbreaking Thursday, May 14, 2026, on a hospital expansion to answer the medical needs of one of the fast-growing sections of the San Francisco Bay Area. 

The 66,000-square-foot wing, to connect to the east side of the hospital, will stand three stories tall — more than doubling the capacity of the emergency department; allowing the hospital’s laboratory, pharmacy and sterile processing center to be relocated to larger spaces; and setting the stage for future expansion.

“For more than six decades, Stanford Health Care Tri-Valley has been a trusted partner for the Tri-Valley community, delivering high-quality, compassionate care close to home,” said David Enwistle, president and CEO of Stanford Health Care. “This expansion reflects our commitment at Stanford Health Care to ensuring patients have access to the care they need — when and where they need it most. With this addition, Stanford Heath Care Tri-Valley is strengthening its ability to serve a growing community, while advancing our mission of exceptional patient care.”

While the population of the Livermore, San Ramon and Amador valleys, which lie on the eastern edge of the Bay Area, has grown, the emergency departments in the region have not. Between 2013 and 2023, Tri-Valley emergency department visits increased by almost 30%.

With the expansion, the Stanford Health Care Tri-Valley emergency department will have 24 additional patient bays and three triage rooms along with a larger patient waiting area. 

“This expansion means more capacity and enhanced capabilities to meet the growing demand of the East Bay’s fastest-growing region while keeping strong community roots that were established over 60 years ago with ValleyCare Health System,” said Misty Jones, MBA, MSN, RN, president and CEO of Stanford Health Care Tri-Valley. 

The addition to the hospital, which was originally built in the 1990s, will involve reconfiguring the road that circles the hospital campus as well as surface parking. The project, expected to be completed in 2029, will include new infrastructure to support the hospital’s operational resilience in the event of a major earthquake.

“When this project is complete, patients will have faster access to emergency care with reduced wait times,” said Brian Kaminski, MD, medical director of the Stanford Health Care Tri-Valley emergency department. “It ensures that life’s most urgent moments are met with the excellence, speed and compassion that define Stanford Medicine.”
