GET TO KNOW
Van Nguyen, DMD
FAMILY AND COSMETIC DENTIST
Born and raised in Vietnam, Dr. Nguyen immigrated to Orange County, California at the age of 10. Her very first dental experience was in the States, when her dentist gave her the confidence she didn’t know she had by straightening her teeth. Ever since then, she’s been inspired to help others harness a lifelong love for their smiles too.
Dr. Nguyen majored in biochemistry and psychology at the University of California, San Diego, and went on to become a Doctor of Dental Medicine at Case Western Reserve University in Cleveland, Ohio. Honing her talents in all facets of general dentistry, including implant dentistry and restoration, she completed her general practice residency at Cleveland VA Medical Center.
Today, she couldn’t feel more grateful to plant roots in Placentia and provide an all-inclusive dental home for local families. For Dr. Nguyen, being a dentist goes beyond just treating teeth. She values learning each patient’s story, connecting with them on a personal level, and partnering alongside them to reach their goals with peace of mind.
When she’s not at the office, you can find Dr. Nguyen spending time with her wonderful husband, Dr. Justin, and her 2 precious kids, Dean and Kelly. Whether it’s sharing a yummy home-cooked meal or traveling to beautiful destinations together, she’s happiest making quality memories with her family.
