Boyce was born to a pair of physicians in Connecticut.
Afterward, she joined the Federation Red Cross.
During the Federation-Tzenkethi War Boyce was working at a hospital that came under siege from Tzenkethi forces. She stayed behind with patients who were unable to be evacuated. A Starfleet force from the USS Ambassador led by Gedna Tachion rescued the patients and Boyce.
Impressed with her rescuers, she decided to apply to Starfleet.
Two months later Boyce was accepted into Starfleet OCS.
When Tachion took command of the USS Vigilant in 2361 he requested her as his Chief Medical Officer. After the loss of the vessel, she took an assignment at Starfleet Earth Command as a Medical Advisor.
USS Lionheart Edit
Coming aboard the Lionheart, she beam part of Tachion's inner circle once again, just like on the Vigilant.
When a trio of scientific teams came aboard the ship to test cloaking detection systems, Satchio Nakamura was assigned to the extra bunk in her quarters, much to her displeasure. ("Blinded by Science")
