The OHSU Emergency Medicine residency program offers a dynamic mix of nationally recognized educators, a variety of clinical training sites offering diverse experiences, strong research and simulation programs, and innovative curriculum design.


The Department of Emergency Medicine at Oregon Health & Science University was established as an interdepartmental division in June 1977, becoming the third U.S. medical school to establish an independent academic emergency medicine program. Since then the Department of Emergency Medicine has experienced remarkable growth in its faculty and programs, receiving full departmental status in April 1992.

The Department of Emergency Medicine has always been deeply committed to the training of emergency medicine residents. The Emergency Medicine Residency Program, originated in 1978, is a fully accredited, three-year program that accepts 11 residents per year at the EM-I level.

Zero Tolerance for sexual harrassment and discrimination

OHSU Emergency Medicine Residency does not tolerate sexual harassment or discrimination in any form.  We are dedicated to the education and wellness of our trainees and have multiple mechanisms in place for confidential and anonymous reporting of concerns.  In our residency we are committed to reporting concerns that come to our attention, fully participating in active investigations, advocating for and supporting our trainees, and transparency within our community. We are continuously working to evolve our culture, policies, and practices to provide an environment where all feel safe and included. We take our roles as educators, physicians, and leaders seriously and are invested in being part of the change that needs to happen across our country to end discrimination and power dynamics that allow for harassment. We remain committed to these ideals and will continue to prioritize them as leaders in emergency medicine education.
