|Dr. Swender||Kimberly Elise||5||3|
|A surgical oncology attending assigned to oversee Izzie Stevens' cancer treatment. She is said to be the best surgical oncologist in the state of Washington. Swender is a proponent for IL-2-use as treatment for cancer; she reasons 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 due to the inherent nature of the IL-2. This has shown to affect Swender's otherwise authoritarian and impartial persona, and casts doubt on this treatment-protocol.|

|A general surgery attending and Seattle Grace's first female surgeon. With forty-years of surgical experience, she is considered a pioneer and one of the hospital's most respected surgeons; it is implied that, in that time, Richard Webber was taught by her as she recalls an incident involving a clamp dropped into an open body cavity, and has worked with Ellis Grey. More recently, Cristina Yang has been vocal about her objections and criticisms of Campbell's continued long-standing service.

|An incompetent pediatric surgery attending brought on as the interim Chief of Pediatric Surgery when Arizona Robbins gave her notice to oversee a pediatric surgery program in Malawi, Africa.

|Dr. Lucy Fields||Rachael Taylor||7||8|

Self-proclaimed as being "damn good at her job," Fields attended Harvard Medical School and completed her OB/GYN residency at Duke University Medical Center.

It also seems that she has a slight crush on Alex Karev, and in Episode 18 they start to form a relationship. Also, Doctor Addison Montgomery comes back and is told that she is not able to deal with traumatic pregnancy cases.(Ex: Callie being pregnant in a car accident). Alex Karev breaks off the relationship he had with Fields in the season 7 finale.|
|Dr. Sydney Heron||Kali Rocha||2, 3, 4||8|

She initially appeared as Bailey's substitute when Bailey was on maternity leave and clashed with Cristina, who finds Sydney's positive attitude unbearable. She later served as Izzie's peer counselor and revealed that her perky persona actually originated from a nervous breakdown she suffered after losing a patient of her own. She was also in the running to become chief resident, but lost to Callie, who was later replaced by Bailey. Sydney also went on one date with Dr. Shepherd, but dumped him when she decided he wasn't ready for the kind of relationship she needs.|
