Andrew Nguyen

Andrew Nguyen is a junior in high school, an International Baccalaureate student, and an Academic Decathlete. Though English is his second language, he picked up a propensity for public speaking through the Boy Scouts of America; a fondness for writing followed quickly after that. Of all his involvements and achievements, he is most proud of the day he became an Eagle Scout. Because of his many engagements, much of his day is spent on schoolwork, though he enjoys making music in what time he can find. From an early age, Andrew also developed an affinity for water, which he has maintained through scuba diving, swimming, and water polo. His ideal career choice is surgery, as he feels that will afford him the opportunity to change lives on a regular and personal basis.
