Teddy attended UT Southwestern and then completed her surgical residency at George Washington University Medical School followed by a fellowship at Mayo Clinic in Florida. She then attained an attending position at a hospital in Columbia, which she gave up after the death of her best friend during the collapse of the second tower during the 9/11 terrorist attacks.
Teddy then enlisted in the US Army as a medic and surgeron, where she met Owen Hunt. She and Owen completed one tour together in Baghdad. Teddy and Owen became very close, with most of their fellow soldiers seeing a romantic undercurrent between them, in spite of Owen's engagement to Beth Whitman. Teddy soon started to develop romantic feelings for Owen, as he did for her, and she believed that if he and Beth ever broke up then they would explore a relationship together. When Owen’s unit was killed, and he was stranded in the desert, Teddy was one of the first on the scene after being heavily involved in the search for him, further emphasising the feelings between the two. After her tour Teddy returned to civilisation and resumed practicing medicine.
