She is a proponent for IL - 2 - use as treatment for cancer, citing its success when a patient, initially given only three months to live, uses the therapy and survives an additional two years . The patient, however, succumbs to complications from the inherent nature of the IL - 2, which affects Swender's otherwise authoritarian and impartial persona, and casts doubt on this treatment - protocol . </Td> </Tr> <Tr> <Td_colspan="5"> </Td> </Tr> <Tr> <Td> Dr. Margaret Campbell </Td> <Td> Faye Dunaway </Td> <Td> 5 </Td> <Td> </Td> </Tr> <Tr> <Td_colspan="5"> A general surgery attending, Dr. Campbell is Seattle Grace's first female surgeon . With 40 years of surgical experience, she is considered a pioneer and one of the hospital's most respected surgeons . Richard Webber may have been taught by her, which is implied when she recalls an incident involving a clamp dropped into an open body cavity . She has worked with Ellis Grey . Cristina Yang has been vocal about her objections and criticisms of Dr. Campbell's continued long - standing service . Due to a complication caused by a lacerated bowel during a routine cholecystectomy, Dr. Campbell retires after performing her last surgery to repair the "careless mistake ." </Td> </Tr> <Tr> <Td_colspan="5"> </Td> </Tr> <Tr> <Td> Dr. Robert Stark </Td> <Td> Peter MacNicol </Td> <Td> 7 </Td> <Td> 7 </Td> </Tr> <Tr> <Td_colspan="5"> An incompetent pediatric surgery attending, Dr. Stark is brought in as the interim Chief of Pediatric Surgery when Arizona Robbins gives her notice to oversee a pediatric surgery program in Malawi, Africa . Under contract for a year, Dr. Stark continues to serve as the department chief when Robbins returns . Described as a lazy doctor and a complacent and self - satisfied attending, he represents the antithesis of attending surgeons commonly employed at Seattle Grace / Mercy West Hospital . Dr. Stark has an antagonistic disposition with most of the hospital staff, especially Alex Karev. April Kepner is the only exception to his behavior . He later attempts to date her, with little success . </Td> </Tr> <Tr> <Td_colspan="5"> </Td> </Tr> <Tr> <Td> Dr. Lucy Fields </Td> <Td> Rachael Taylor </Td> <Td> 7 </Td> <Td> 8 </Td> </Tr> <Tr> <Td_colspan="5"> An OB / GYN attending and maternal - fetal medicine fellow at Seattle Grace Mercy West, Dr. Fields is self - proclaimed "damn good at her job ." She attended Harvard Medical School and completed her OB / GYN residency at Duke University Medical Center . Dr. Fields is Callie Torres' obstetrician and shows that she is equal parts tough, ironic, and empathetic, especially when dealing with Torres and her support team: Mark Sloan and Arizona Robbins . She seems to have a slight crush on Alex Karev, and they begin to form a relationship . Dr. Addison Montgomery returns and is told that she is not able to deal with traumatic pregnancy cases (such as a pregnant Callie involved in a car accident). Alex Karev breaks off his relationship with Dr. Fields in the Season 7 finale, and she goes off to treat children in Africa . </Td> </Tr> <Tr> <Td_colspan="5"> </Td> </Tr> <Tr> <Td> Dr. Nicole Herman </Td> <Td> Geena Davis </Td> <Td> 11 </Td> <Td> 8 </Td> </Tr> <Tr> <Td_colspan="5"> Nicole Herman was the Head of Fetal Surgery at Grey Sloan Memorial Hospital. Arizona worked with her as a fellow . It was revealed that she has an inoperable brain tumor and only has 6 months left . She wanted to use this period of time to teach Arizona about Fetal Surgery since it is a new field . When Amelia informed her that she believed she could remove the tumor, Herman initially rejected the idea, because she'd been given hope many times before and then had it taken away . Amelia operated and despite some complications, she successfully removed Nicole's tumor . However, she didn't wake up for several days after the surgery, leading Amelia to look for a cause . An MRI showed signs of a stroke and Amelia worried she'd never wake up . Despite this, she did eventually wake up . She was full aware of her surroundings and showed no loss of mental faculties, but she was completely blind . After being discharged from the hospital, Herman went to the Blind Institute, where she learned to live her daily life as a blind person . </Td> </Tr> </Table> <Tr> <Th> Name </Th> <Th> Actor / Actress </Th> <Th> Season (s) </Th> <Th> Episode count </Th> </Tr>
