Announcement from Dr. Joann J. Toy and Dr. Tyrone Chan


Our top priority is the health and well-being of our patients, families, staff and community. In this unprecedented time, we are deeply committed to keeping everyone safe. 

In light of the evolving pandemic and out of an abundance of caution, we have decided to close our practice for the next 2-3 weeks. We believe that this closure will allow us to more effectively evaluate this dynamic situation and assist in following the CDC’s guidance on social separation. If you have an appointment scheduled with us this week, our office will be in touch to help reschedule your appointment. 

There WILL be a dentist on call in the event of a dental emergency. Should you require emergency dental care, please call our office at 650-757-9490 as you normally would and one of our dentists will contact you. 

We did not make this decision lightly. A great deal of care, research and planning guided our decision. We will continue to evaluate the situation as it evolves and determine on a weekly basis when it is appropriate for us to return to our normal business hours.

Again, please understand that we are making this decision with the health and well-being of our patients, our families, our team and our community in mind.

We  wish all of you continued health and strength during this challenging time.
