From his earliest days in the classroom, Dr. Kevin R. Perusse, a board-certified diagnostic radiologist at Radiologic Associates of Fredericksburg (RAF), was captivated by the life sciences. When his father, a career military officer, moved the family to Panama for three years while Dr. Perusse was still in grade school, the lush rainforests, diverse wildlife and other natural wonders of “the Crossroads of the Americas” enhanced his fascination with biology. “Eventually, after many years of looking into the microscope, I decided the best way to focus my interest was in helping people through medicine,” he said.
