Dr. Nguyen attended the University of California, San Diego where she earned her Bachelor of Science and Master of Science degrees. She received her medical training at Michigan State University, College of Medicine. After medical school, Dr. Nguyen returned home to Southern California and spent the next three years at the University of California, Riverside for her internship and residency training in Internal Medicine. Dr. Nguyen then completed a one-year subspecialty training in Hemostasis and Thrombosis at the University of California, San Diego.

Dr. Nguyen was born and raised in Vietnam. She immigrated to the United States along with her family at the age of 13. The poverty and lack of sufficient medical service in her birth country ignited her childhood dream of becoming a competent and compassionate physician for all. Dr. Nguyen embraces the special patient-physician relationship, the opportunity to understand each individual, and to assist with their healthcare needs. She keenly believes that preventive care along with early diagnosis and proper management is the fundamental essence to improve one’s quality of life.

In her spare time, she enjoys reading, outdoor activities, traveling, and spending time with her family. She is blessed to be the mother of a two-year-old boy who has taught her to live, laugh, and love in the simplest ways. Dr. Nguyen is fluent in English and Vietnamese.
