Joan White, RDH

Good oral health is of paramount importance to overall wellbeing. I feel tremendous gratification when my patients trust me to provide thorough and gentle treatment, and to encourage them to make good dental health essential to their lives.


A seasoned hygienist with over 35 years of experience, Joan has worked in this office since 1988 and has been caring for her patients with her gentle touch and encouraging spirit ever since. Her career has taken her from working as a dental assistant to providing dental hygiene care to the underprivileged in rural Mexico alongside the “Flying Doctors.”


Joan holds a Bachelor of Arts degree in psychology from the college of Notre dame, as well as a dental hygiene degree from Foothill College. She is the recipient of the Hu Friedy Golden Scaler Award, a national award for clinical and technical excellence. Joan is also LASER certified.


When Joan isn’t busy caring for her patients, you can find her hiking, bicycling, gardening and attending the theater with her husband.



Benjamin Mendoza, RDH

I love practicing dental hygiene because it allows the confluence of my two greatest passions: the study of science and the care of others.

Benjamin began his career in dentistry over 17 years ago as a dental assistant and as a laboratory technician where he honed his understanding of the science and technology of delivering dental care. His passion for caring for others and education led him to pursue dental hygiene so that he could directly participate in the lives of his patients and help them to follow a path to better health and wellness. Since earning his associates degree in Dental Hygiene from Carrington College, Benjamin has pursued numerous educational opportunities and is well-versed in decay prevention strategies, LASER periodontal therapy, the whole-health ramifications of periodontal disease, and hygiene instrumentation.

When he isn’t working with his patients, Benjamin can be found in the South Bay where he lives with his wife and two children. He enjoys weight-lifting, jiu jitsu, and serving in the youth ministry.



Debbie Kanagaki, RDHAP

I am committed to providing my patients with optimal care designed to benefit their oral and total health. I pride myself on practicing ethically and putting my patient’s best interest first.


Debbie brings over thirty five years of dental experience to our practice. Over the course of her career, Debbie has pursued skills in several areas of advanced hygiene practice including the use of LASERS, local pharmacotherapy, dental anesthesia, and DNA / microbiological testing. Debra’s years of experience alongside periodontal surgeons allows her to bring a higher level of knowledge and ability to our patients. As a registered dental hygienist in alternative practice (RDHAP), Debbie has achieved one of the highest levels of education available to hygienists. The requirements for this level of certification are rigorous and include over 35 hours of continuing education and thousands of hours of experience. As an RDHAP, Debbie is one of the few hygienists in California licensed to operate independently.


Debbie was raised right here in the bay area where she now lives with her two sons, Mitchell and Garrett.
