After graduating from Harvard Medical School with a concentration in critical care, Dr. Calderón opted to complete post-graduate medical training in the field of Family Medicine, at Kings County Hospital/Downstate Medical Center, Central Brooklyn, where he grew up as a child. Contrary to advice from the medical school’s dean of students to seek residency training at a program associated with a more prestigious medical school, Dr. Calderón chose to train in that poverty-stricken, medically underserved population, having an infant mortality rate that was greater than many underdeveloped third world nations. He purposefully did this at the time when Central Brooklyn was the epicenter of the HIV/AIDS epidemic. Dr. Calderón was told by the same dean of students that he was wasting a Harvard Medical School education by choosing to go to Central Brooklyn. With unwavering conviction, Dr. Calderón responded, “The poor deserve Harvard educated doctors as much as anyone, and perhaps more so.”
