Dr. Khuong Nguyen enrolled at the University of California, San Diego, after graduating high school in 1988. He obtained his Bachelor of Science in Biology degree in 1993. He attended the University of Southern California, also known as USC, for dental school. After finishing his undergraduate studies in 1997, Khuong participated in the Advanced Education in General Dentistry program at the University of California, Los Angeles.

Dr. Nguyen entered the practice after completing this phase of his education, but he quickly recognized that pediatric dentistry was his genuine passion. He completed a two-year pediatric dentistry residency at Lutheran Medical Center in Brooklyn, a teaching affiliate of the New York Health Science Center so that Dr. Khuong may follow his career aspirations.
