In 2000 she moved east to attend medical school at Tufts University. Sarah then returned to California to attend a Combined Internal Medicine and Pediatrics Training at UC Los Angeles. While her intention was to become a primary care doctor for kids and adults, she was drawn to diabetes care.

Dr. Kim pursued an endocrinology fellowship at UCLA, completing this in 2010. She then went on to complete the UCSF Advanced Diabetes Fellowship in 2010-11 focusing on diabetes management in the adult, pediatric, pregnant and hospitalized population.
