Dietitian Brings Passion, Expertise to Fellow Runners

Team dietitian Sara O’Brien is a Lahey employee, a dedicated runner and a cancer survivor. It was her determination to keep running, to keep helping her patients, and to keep living that drove Sara O’Brien to fight her breast cancer diagnosis head-on.

After going through chemotherapy in 2012, her cancer went into remission, and Sara got right back on the track. To pay it forward, she runs the Lahey Cancer Institute 5K Walk & Run every year to raise money for Lahey Hospital & Medical Center, where she was treated. She credits the doctors there with saving her life. In August 2019, Sara ran the Falmouth Road Race as part of Team Lahey, again raising funds for the hospital.

Sara isn’t just a patient. She has worked for Lahey Hospital & Medical Center for almost eight years as an advanced practice registered dietitian, one of only 53 in the country. She holds a master’s degree in nutritional sciences from Boston University and she is certified to care for patients with specialized nutritional needs.

Her passion is sports nutrition. It makes sense; she’s an accomplished runner. Sara was the state and New England Track Champion when she ran for Reading Memorial High School. She was an All-Ivy runner at Columbia University, where she earned a bachelor’s degree in chemical engineering. She also ran for 10 years for the Greater Boston Track Club.

Team Lahey is grateful to have Sara working with our runners.
