Mercy West Medical Center

Mercy West Medical Center was a rival teaching hospital to Seattle Grace Hospital in Seattle, which has been described as on "the other side of town." In season six, Mercy West merged with Seattle Grace. During the merger, the Seattle Grace resedents were intimidated by the Mercy West resedents because of their excellent medical and surgical skills and also the risk the new resedents posed on the current ones' jobs because of the financial factors that caused Mercy West and Seattle Grace to merge.

Season Two
Preston Burke and Erica Hahn fought over a donor heart for their patients (GA: 17 Seconds).

On Thanksgiving, Dr. Kent worked as a temp attending at Seattle Grace. He was said to be from Mercy West. (GA: Thanks for the Memories)

An intern from Mercy West named Marshall was admitted after causing an accident. (GA: Damage Case)

Season Three
George O'Malley applied to become a resident at Mercy West. He was accepted pending the result of his intern examination. However, he failed and instead came back to work at Seattle Grace.

Season Six
As Richard Webber couldn't promote her, Callie Torres left Seattle Grace and became a surgeon at Mercy West instead. Richard Webber was later admitted after being involved in an accident and had an intern, Dr. McKee as his doctor.

Merger with Seattle Grace
Despite rumors that Richard would be leaving Seattle Grace to work at Mercy, he soon revealed that Mercy West and Seattle Grace Hospital would be merging. However, some employees from both Mercy and Grace would be let go.

Notes and Trivia

 * The surgical residents wore orange scrubs.
 * It is likely that Dr. Kent is a general surgeon as he requested a surgical resident (i.e. Miranda Bailey) to supervise, and overseeing incoming surgical emergencies. Although it is possible that Dr. Kent is a trauma surgeon, it is unlikely as Grey's Anatomy did not feature this specialty until season five.
