Our Doctors

For Patients

Stanford Health Care (formerly Stanford Hospital & Clinics) is known worldwide for the advanced patient care provided by its doctors and staff.  We also provide a wide range of guest services and amenities to our patients and visitors. Learn more about preparing for a hospital stay, billing and financial services, and our other support programs in Patients & Visitors.  


Emergency room visits outside clinic hours no longer require pre-authorization by your doctor, by California State Law. Make sure you inform your physician within 24 hours following your visit.

Be aware of your health plan limitations - unless you require 911 emergency transport, some health plans require you to obtain all after-hours emergency care at Stanford ER if you have a primary care doctor at Stanford.

A physician is on-call after hours to coordinate any emergency care needs which arise after-hours and can be reached at the 24 hour number: 650-498-9000.
