COVID-19 UPDATE - 7/14/2020 

Updated Visit Policy

For the safety of our patients, their families and our staff and in keeping with local mandates which are enforced by the Department of Helath AND CDC recommendations we are making the following changes:

1.  Families are required to wear a face masks during the visit.  We will be asking that all children over 5 years of age wear a mask.  However it is recommended by the CDC that masks should be worn by everyone over the age 2 years.  

2.  Visits will be limited to the patient and only 1 parent or guardian per patient seen in our office.   We are happy to discuss the case over the phone with other members of the family.  We will be unable to allow other family to wait inside the waiting room and instead will need them to wait outside the pracitce.

3.  We can no longer allow other children in the family to be present for the apppointment unless they are also being seen.
