COVID-19 Advisory

We are asking all our patients to come alone or bring only ONE adult member of the family with them to each appointment. We are doing our part in limiting contact during this unprecedented time. We are actively disinfecting our doors, waiting room environment and obviously anywhere our staff and our patients go within our office. We check our staff and provider’s temperature and overall health every day. We ask that if you are having a high temperature, cough, sore throat, shortness of breath or any other respiratory symptom to call our office and we will guide you over the phone on what to do and what is needed.
