Growing up in the former South Vietnam, D. B. "Zoon" Nguyen was deemed too slow mentally as a child and after he received 32 consecutive zeroes in school, his parents were advised to keep him home. He did not start first grade, nor second grade, with other children, and was taken to school half way through second grade only so that he could learn to make friends. It took him one year to learn to subtract with carry, and even longer to understand fractions, but after that he improved. (At age 12, he was awarded the (South Vietnam) Presidential Award.) When South Vietnam fell in 1975, he came to America with his family as a refugee, and started high school in Virginia but finished it in Seattle. During his senior year, he took mathematics and physics courses at the University of Washington, discovered a way to visualize four and higher dimensions as a delegate at the NYSC, and received a scholarship to Harvard where he graduated magna cum laude with highest honors. Zoon went on to obtain an MD and PhD from Dartmouth, post-doctoral training at Yale, and become a NATO Fellow to Denmark where he learned Danish, Norwegian, and Swedish as a guest professor at Aalborg University in Aalborg, Denmark. On a trip from Denmark to Italy, Zoon solved a problem, for which he was later awarded a US Patent. Dr. Nguyen completed his internship and residency at Yale and is a diplomate of the American Board of Radiology and a diplomate of the National Board of Medical Examiners. He was President and CEO of American Radiation Oncology, is currently a radiation oncologist, and recently became engaged to a concert pianist. His first loves being mathematics and the piano, he lives in Mansfield, OH, with his fiancee and two small cats.
