Our Mission

To fuel the self-confidence and quality of life for all, one smile at a time.

We aim to achieve the functional, esthetic, and oral well-being that you desire through technical excellence and superior skills while respecting your concerns, comfort and peace of mind.


Bi-Lingual Dentist

When you have a dentist that speaks the same language (both literally and figuratively), getting your dental care completed is easier and a more comfortable experience. Originally born in China, Dr. Lily speaks Mandarin as well as English, making it easier for those who prefer speaking in their native language. The result is a dental care experience that feels truly accommodating, no matter what treatments you need to have completed.

Member of the Academy of Aesthetic and Cosmetic Dentistry

While any dentist can call themselves a cosmetic dentist and provide cosmetic dental treatments, it’s important to recognize those who actually take the time to hone and perfect their techniques and technology surrounding cosmetic dentistry. Dr. Lily is proud to be a member of the Academy of Aesthetic and Cosmetic Dentistry, which allows her to stay on the forefront of advancements in the field. When you want an appearance that makes you feel confident, you’ll want a dentist who has the experience to make your dream smile a reality.
