The following personnel were employed or patients at Mercy Hospital in 1986.





Interns in elevator

These two hospital interns talked about the different views of Doctors Gottlieb and Weintraub regarding an unnamed patient's treatment while using the elevator. When Kirk, Gillian and McCoy joined them, McCoy compared their discussion, which concerned radical chemotherapy and image therapy, to the Spanish Inquisition. (Star Trek IV: The Voyage Home)

Operating team

Two doctors and two nurses prepared the operation for Chekov following his fall from the aircraft carrier USS Enterprise CVN-65. When Kirk, Gillian, and McCoy came in to treat and kidnap Chekov, the team was jailed in a small room behind the operation room. The young doctor previously asked McCoy if he had his doctorate in dentistry following McCoy's comments about medievalism. (Star Trek IV: The Voyage Home). McCoy tells the doctor that the artery must be repaired to save Chekov rather than simply drilling into his skull. Kirk, using his Klingon phaser, locks the doctor and his staff in a small supply room so that McCoy can help Chekov undisturbed.

Only the first actor received credit for his appearance.
In the short story "Whales Weep Not" by Juanita Nolte contained in the anthology Strange New Worlds VI, one of the doctors was given the name Brickman.
