Our residents benefit from a robust team of formal and informal mentors and collaborators.


Imagine having the recognized leaders in their field as your mentors, providing guidance on clinical practices and professional development. Our faculty have written THE textbooks, lead emergency medicine organizations, and in some cases, pioneered their sub-specialties. Best of all, they are passionnate about shaping the next generation of physicians, day-to-day and with an eye toward long-term goals.


Physical proximity to Stanford Hospital and Stanford University allows interdepartmental and interdisciplinary collaboration with researchers and healthcare providers who are changing medicine. The School of Medicine current faculty roster includes eight Nobel Prize winners, and Stanford is home to a long-list of firsts, including the first heart transplant in the United States.
