John Muir Health Walnut Creek Medical Center
Surgical Critical Care
Dr. Diaz is a trauma and acute care surgeon with specialty training in surgical critical care. He was born and raised in Monterrey, Mexico and attended medical school at Monterrey Tech School of Medicine in his hometown. After that he obtained an MPH in Quantitative Methods from the Harvard School of Public Health and went on to work as a research assistant at the Harvard Center for Surgery and Public Health for a year. During this time, he participated in research related to improving outcomes in surgery, specifically, efforts to prevent surgical errors. In 2008, he did his general surgery internship at Brigham and Women’s Hospital in Boston and then transferred to the University of Texas Health Science Center at San Antonio for the rest of his general surgery residency. During this time, he realized the challenges of trauma surgery and the satisfaction of helping patients through such trying times were his passion. He then completed a Surgical Critical Care fellowship at UTSW in Dallas. He stayed on for an additional year as an assistant instructor and trauma fellow to get as much experience as possible from the very busy Rees-Jones Trauma Center at Parkland. In 2018, Dr. Diaz and his wife, Dr. Yanett Anaya, who is a reproductive endocrinologist that trained at the University of California San Francisco, moved to the Bay Area so that she could return to UCSF as an assistant professor and he could join BASS Medical Group as a trauma and acute care surgeon. Dr. Diaz is board certified by the American Board of Surgery in both General Surgery and Surgical Critical Care and is a member of the Eastern Association for the Surgery of Trauma and the Society of Critical Care Medicine. Outside of the hospital, Dr. Diaz enjoys spending as much time as possible with his wife and their dog, Charlie.
