Covid-19 Office Update

Dear Patients,

Sadly, the office re-opening has been delayed.

The Governor of Massachusetts will be issuing a directive on the start date for dentists on May 18 and we will not be re-opening that day as planned.

I am projecting the office re-opening after Memorial Day but I cannot be specific on the exact date until Governor Baker announces his plan. Massachusetts has been hit especially hard with COVID-19 and these delays are for everyone’s safety. We are busy behind the scenes preparing for a safe and effective opening that will maintain good health for patients and staff.

Please be patient. We all miss you and we will update you as we have the information.
I will be keeping up-to-date information on my website as well.

Dr. Rizza
