He joined the faculty as a Clinical Instructor of Infectious Diseases in 2008 and then as an Assistant Clinical Professor of Internal Medicine in the Division of Hospital Medicine in 2012 with the goal of applying his skills towards improving care and care delivery. Throughout his career, Dr. Ortiz has distinguished himself as a multifaceted leader, holding important roles within UCSF and the San Francisco Department of Public Health.

Highlighting his commitment to our key values, he has served as a Medical School Bridges coach, has been recognized with the Excellence in Teaching Faculty Award in 2019 by the UCSF graduating medical school class, and has twice been awarded the Values in Action Award by the Medical Executive Committee. He is an enthusiastic Lean leader, having completed Lean Certification in April 2014 and continuing to apply the principles of respect for people and enhancing value to his work across the Department of Medical/Surgical care and in his Chief of Staff role.
