Dr. Schwartz is a doctor who works at Starling General Hospital.
Laurel Lance was brought into Starling General Hospital in her Black Canary suit. Dr. Schwartz and the trauma team tended to her, helping her recover. However, despite being in the clear, she eventually began seizing, to no avail. Oliver Queen returned later to thank her for her doctor-patient confidentiality regarding Laurel and Oliver's secret identities. He proceeded to ask her regarding an impostor tarnishing Laurel's reputation, but she was unable to give a name.
