He is a Bowdoin College graduate and attended Columbia University College of Physicians and Surgeons alongside his childhood best friend Mark Sloan and ex-wife Addison Montgomery and Private Practice characters Naomi Bennett and Sam Bennett . Derek was a student of Chief Webber and was enticed to come with an "offer he couldn't refuse"--the position of Chief of Surgery, which Derek eventually turned down . He specializes in highly complex tumors and conditions of the brain and spine and came to Seattle Grace with a reputation for taking on "lost causes" and "impossible" cases that most of his peers would turn down . As an attending he is both well - liked and feared--well - liked by patients and his scrub nurses for his compassion and gentlemanly bedside manner and feared by interns and residents who are intimidated by his reputation and high standards . He is passionate about his job and has been known to expel staff or remove interns and residents (or at least threaten them) from his service for being disrespectful about patients or if he deems their attitude to be detrimental to his patient's well - being . </P>
