Arizona Robbins is a fictional character on the ABC television series Grey’s Anatomy,
portrayed by Jessica Capshaw. She was introduced in the show’s fifth season as an
attending surgeon and the new head of pediatric surgery. Originally contracted to appear
in three episodes, Capshaw’s contract was extended to the remainder of the fifth season,
with her becoming a series regular in the sixth season.
Arizona has a “quirky” personality, and a costume designed to appeal to her young
patients, including roller shoes and a Holly Hobbie pink scrub cap. She was established as
a love-interest for orthopedic resident Callie Torres, whose previous girlfriend Erica Hahn
was written out of the show earlier in the season due to an alleged lack of chemistry
between the two. Series creator Shonda Rhimes was in contrast pleased with the chemistry
between Arizona and Callie, citing the addition of Capshaw as Arizona as an element of the
season of which she was most proud.
