Dr. Nguyen received his medical degree from the University of Massachusetts Medical School where he was the recipient of the Senior Scholar Research Award and the John S. Efstathiou Memorial Award for “demonstration of compassion and understanding of patient and their families in difficult times.”

He then moved to Southern California and completed his Internal Medicine training at the University of California, Irvine Medical Center in Orange and at the Veteran Administration Hospital in Long Beach, California. Following his residency training, Dr. Nguyen completed a fellowship in Gastroenterology at the University of California, Irvine Medical Center where he was trained by top experts in the field of Gastroenterology. During his training, Dr. Nguyen was active in clinical and basic science research and has published over 15 articles and abstracts in the field of gastroenterology and hepatology. His work has been recognized and selected for oral presentation at several major gastroenterology conferences.

After completing his training, Dr. Nguyen was recruited to establish his practice in the High Desert community. Through his strong work ethics and dedication, Dr. Nguyen quickly gained the trust and respect of his patients and peers and has built a solid foundation in the High Desert community. Dr. Nguyen is committed to provide the best and most up to date sub-specialty care.
