Stephen Clarks is a character who appears in Under the Knife, Second Opinion and Under the Knife 2. Stephen is kind and caring, which comforts many sick patients. Apparently, he didn't do a very good job against Deftera, being only able to thin out some of their tumors. It was originally intended for him to operate on Linda Reid when she had Post-Kyriaki, but seeing Linda is more of Derek as he operated on her before he let him do it instead. He is head surgeon at Caduceus USA in Under the Knife, Under the Knife 2, and Second Opinion.
