Erica Hahn

Erica Hahn is a fictional character from the American Broadcasting Company (ABC) medical drama television series Grey's Anatomy, portrayed by actress Brooke Smith. Hahn was a recurring character through the show's second and third seasons, and joined the main cast in the fourth season. Prior to assuming the role, Smith observed heart surgery being performed, and admitted to finding the pressure of maintaining a realistic portrayal of a medical professional stressful.

The character is presented as highly professional, to the point of being a "workaholic". She was notably hard on Resident Cristina Yang (Sandra Oh), admitting that Cristina reminds her of herself as a student. Despite her intentions to keep away from relationships, she becomes romantically involved with orthopedic surgeon Callie Torres (Sara Ramirez). The storyline has been praised for its realistic portrayal of a developing lesbian relationship, although consultants from the Gay & Lesbian Alliance Against Defamation have expressed some concerns over the somewhat exploitative talk of a threesome between Hahn, Torres and Sloan. Hahn was written out of Grey's Anatomy in November 2008, with Smith commenting that the decision originated with the ABC network, rather than series creator Shonda Rhimes.
