Upon arrival at Seattle Grace, Burke was shot and Hahn was needed to do the surgery.
Just remember that while you're still sitting on two hundred grand of student loans... Izzie Stevens was a surgical resident at Seattle Grace Hospital until she was fired shortly after the merger with Mercy West Medical Center.
Because of her pregnancy, mothers made their children stay away from Izzie so she had no friends. She paid for medical school by modeling for designer "Bethany Whisper," which led to her receiving the nickname, Dr. She attended University of Washington School of Medicine Izzie met Denny Duquette, a heart patient, who immediately took a liking to Izzie.
How does anybody practice medicine hauling these things around? This forced Izzie to pay most of the bills with her own money.
She lived in a trailer park with her mother who nicknamed her "Cricket." As a teenager, Izzie worked as a waitress and had savings for college but her mother spent most of the money on psychics.
