Theodora Grace "Teddy" Altman, M.D., F.A.C.S. is a fictional character from the ABC medical drama Grey's Anatomy. The character was created by series producer Shonda Rhimes, and is portrayed by Kim Raver. She was introduced as a recurring character in Season 6, but is later upgraded to series-regular in the same season after Katherine Heigl's departure from the series.
Altman was conceived as the third major cardiothoracic surgeon attending on the series, following the exits of Preston Burke (Isaiah Washington) and Erica Hahn (Brooke Smith). In the storyline, Altman is brought in as a mentor for Cristina Yang (Sandra Oh) at the suggestion of Owen Hunt (Kevin McKidd), who had served with Altman in the military. This mentorship develops complications when a past connection between Owen and Teddy creates a love-triangle involving Yang.
Another notable storyline includes Altman's relationship with Henry Burton (Scott Foley), a patient she marries to provide healthcare coverage, only to eventually fall in love with him. Raver's initial stint on the show lasted from 2009 to 2012, ending with her departure in the Season 8 finale.
Altman reappears in Season 14 after a five-year absence when it is revealed that she helped identify Megan Hunt (Abigail Spencer), Owen’s presumed-dead sister, who is found alive. In Season 15, Altman is upgraded once again to a series regular after it is revealed she is pregnant with Owen’s child. Since her return, her storylines have focused on her involvement in multiple love triangles, including with Owen, Amelia Shepherd (Caterina Scorsone), and Tom Koracick (Greg Germann).
Altman's backstory also reveals she had a romantic relationship with Allison, her best friend who died during the 9/11 attacks. This revelation confirmed Altman's bisexuality, a significant development in her character's arc. Eventually, Altman ascends to the role of Chief of Surgery, succeeding Meredith Grey (Ellen Pompeo) in the position.
