Chicago Med Wiki

Nurse Doris is an Emergency Department Nurse at Gaffney Chicago Medical Center. She is portrayed by Lorena Diaz.


While she always does her best for her patients and is dependable in a crisis, she doesn't shy away from making the occasional sarcastic remark or joke at a co-worker's expense, at one time referring to Natalie Manning as an "ice princess" when she thought Natalie was out of earshot.

Season Six

When Did We Begin to Change

Doris is seen administering COVID-19 rapid tests to hospital staff before they can enter.


  • Before she began to star on Chicago Med, she had a guest role on one episode of Chicago P.D. as Nancy Moreno, a Registered Nurse;
