Kois Center – Brief History and Philosophy

Dr. Wu is Kois Trained

Kois trained dentists are passionate about what they do

Kois Dentists look forward to Monday. They love the work week, and they love to work with their patients. It’s a different kind of dentistry. Kois dentists are passionate about what they do, or they wouldn’t be taking extensive continuing education training. At Kois Center, the dentists are learning, so they are not just good dentists but great dentists. Their patients are their friends, neighbors, and they see them in the grocery store, and they want to be proud of what they’ve done.

The Kois Center is part of an educational network inspired by Dr. John Kois and populated by Kois trained dentists committed to a rigorous education program. Many Graduates go on to become Mentors and Clinical Instructors, returning to help the next generation of dentists go from good to great. The collaboration of these members has created an ever-expanding knowledge base at the Center and is a pathway for extraordinary professional growth.



Dr. Wu in Her Patients’ Words

“Dr Wu makes sure that you are comfortable and leaving their office knowledgeable and happy with your experience. She is very thorough, personable and knowledgeable. She puts you at ease if you have any worries. She also goes over your dental needs completely and makes it to be easily understood.”

Berna C.

“Dr. Wu’s philosophy is one of spending time with her patients to inform and include them in their treatment, with no judgement. She immediately puts me at ease and explains everything that is happening clearly throughout the whole process. Two weeks later I am a regular patient, and my teeth are much cleaner and happier.

“I went in for a consultation to see what might be going on with a root canal tooth that hasn’t been feeling right. Dr. Wu took her time to make sure and explain everything in detail to me and answer all of my questions. Definitely recommend!”
