About Me

*Dr. Nguyen is only accepting patients 18 years old and over.

Au-Co Nguyen, DO, studied osteopathic medicine at Midwestern University in Arizona and went on to complete a family medicine residency at Community Health of South Florida, Inc. Dr. Nguyen also completed a geriatric fellowship at Aventura Hospital and Medical Center in Florida. She chose a career in geriatric medicine because she wants to make a difference in patients' lives, both mentally and physically. Geriatrics is a subspecialty needed for the aging. With the growing aging population with complex health issues, such as polypharmacy and dementia, she wanted to be part of this subspecialty that is able to give a different approach in medicine and give patients the best quality of life.

Dr. Nguyen’s grandmother played a big role for her to become a geriatrician. She had Alzheimer’s disease and dementia, which also caused many other health issues. Dr. Nguyen would like to help her patients live the best lives they can.

As a physician, I will listen to my patients and try different approaches to their health. Medicine is an art and is not black and white. I make sure my patients' needs are a part of their health plan.

Dr. Nguyen grew up in Huntington Beach, California. Outside of medicine, Dr. Nguyen enjoys doing yoga, kayaking, paddle-boarding, and playing with her dog, a springer spaniel named Lady, who is trained to hunt for truffles.
