The Commonwealth of Massachusetts has issued a “stay at home” order. Starting Wednesday March 25, 2020 we will be forced to shut down and cancel all appointments for the next two weeks. We will be monitoring the office and our phones for emergencies. Once the “stay at home” has ended and we are back to work we will reschedule all appointments. If this is a true emergency please call our office at (508) 261-5207. Thank you for understanding during this difficult time.
