"It is said that 'if the eyes are windows to our souls, then the teeth are windows to our health.' At Forever Smiles Family Dental, we believe in patient care through evidence-based dentistry and utilizing advanced technology and skills for diagnosis, treatment, and prevention. Our mission is to improve and enhance our patients’ oral health, thus providing better quality of life. " Lanthi Nguyen, DMD

Dr. Lanthi (Lanny) grew up in Southern California and graduated with a bachelor degree in Biological Sciences from the University of California Irvine (UCI). She obtained her Doctorate of Dental Medicine (DMD) degree from Western University of Health Sciences in which she was rewarded Dean’s Honor, an academic award recognizing the level of highest scholarship demonstrated by a dental graduate. Dr. Lanny has never forgotten where she came from because as the oldest child in the family and the first to ever go to college, she has have to face many hurdles in order to be where she is today. Her resilience is fueled by her lifelong mission to help others, for she has experienced and understands the value of self-improvement. It is why, even though she is excited to have her first baby, Dr. Lanny is still seeing patients and taking extra continued education courses because she loves dentistry and wants to help her patients achieve their best health.

"Growing up in hardships and overcoming challenges, I carry my work ethic over to my practice philosophy in treating patients. I relate and empathize with my patients, with their struggles and needs, and thus I want to put their best interests at heart. I love to transform one smile at a time." Tin Nguyen, DMD, FICOI, FAAIP.

Dr. Tin grew up in Kent, Washington, and graduated with a bachelor degree in Chemistry from the University of Washington (UW). He attained his Doctor of Dental Medicine (DMD) degree from Western University of Health Sciences, where his top clinical skills are recognized among his faculty and colleagues. To this day, Dr. Tin is always striving to provide the latest and highly desirable treatments for his patients; he is a Fellow in the International Congress of Implantologists (FICOI) and the American Academy of Implant Prosthodontics (FAAIP), distinguishing Dr. Tin as among a select group of dentists across the U.S. with extensive knowledge and experience in implants. The Fellowships are honors held by Dr. Tin reflecting his commitment in countless continuing education hours and training and having passed examinations that result in a strong foundation of quality treatment for his patients. Additionally, throughout his career, Dr. Tin is an advent volunteer, one of which is the Union Gospel Mission where he continues to this day.

Andy Nguyen, DDS

“I was the kid who ate a lot of candy and didn’t floss. Not surprisingly, I ended up with toothaches and grew up feeling hopeless about my teeth. Ironic, isn’t it? Because now I’m a dentist, and I haven’t had a cavity in over a decade. But I never forgot where I came from, and I want to help others know that it is possible—to lift yourself up from wherever you’re from and obtain that confident, brilliant smile that you deserve.” Andy Nguyen, DDS.

Dr. Andy (Long-Quan) grew up in Southern California and graduated among the top of his class as Magna Cum Laude with a bachelor degree in Biological Sciences from the University of California, Irvine (UCI). He got his Doctor of Dental Surgery (DDS) degree from the University of California, Los Angeles (UCLA), the most prestigious dental school in the West Coast comparable to the Ivy League, where he was taught under world-renowned doctors, scientists, and researchers. Dr. Andy has always been passionate about learning and graduated as ranked #1, earning him the title as Valedictorian, in both middle school and high school, and it is through his love of helping others that has motivated him to continue to learn up to this day. He is always striving to achieve the best quality of care for his patients. Dr. Andy also has had extensive experience with pediatrics and loves working with kids as well as anyone aged 0 to infinity.

Front office coordinator

BRACE yourself for my charm and wit, I know the DRILL. I provide excellent service and will never leave you feeling BRUSHED off. I would like to remind you to be nice to your dentist-- they have FILLINGS too! Hi my name is Aimee! I am the one you will talk to first when you call or come into our office. I moved to Tri-Cities in 2016. A smile says a million words and is one of the first things I notice in a person. My favorite thing about dentistry is helping people gain the confidence to smile. When I am not working, I love hanging out with my cats Lola and Monster.
