We are so excited to announce that we will begin seeing patients regularly again as of Tuesday, May 19th and scheduling routine hygiene visits in June.

We have implemented a number of new safety measures in accordance with the California Department of Public Health to add to our already extensive infection control protocols;

  1. Face masks or face coverings will be required to enter the office and should be worn at all times when we are not working on you.

  2. Guests/companions will not be allowed in the treatment rooms unless absolutely necessary.

  3. Please text or call us when you arrive so we can let you know when your room is available. We are trying to minimize people in the waiting room as much as possible.

  4. When making appointments, we will go through a series of screening questions per the California Department of Public Health. These same questions will need to be answered the day of your appointment.

  5. You will be asked to wash your hands upon arrival and we will be taking your temperature prior to entering the treatment room to check for fever

  6. You will notice our clinical team wearing a lot more gear (PPE). This is in accordance with the CDPH and California Dental Association recommendations

  7. We have new medical grade HEPA air filtration units in every dental room and throughout the offices!

Our team will be working diligently to get all of the appointments that had to be cancelled due to COVID-19 rescheduled as quickly as possible. Please be patient with us as we work through the lists chronologically.

As always, we are here to answer any questions you have in addition to taking care of any urgent dental needs. Thank you for your patience and understanding throughout this difficult process. We look forward to seeing all of your smiling faces again soon!
