Practice News

To Our ABC Patients and Families,

We wanted you to be aware that we are taking extra precautions due to the COVID-19 outbreak and are following CDC recommendations for patient care.

We have changed our protocols in an effort to help decrease the spread of infection. Effective immediately, we will be having patients/families wait in their car.  You will contact the office upon your arrival and we will indicate whether you are able to come up or we will call you back once a room is available. Sick patients will enter the office through our back door, marked Sick Visits, and well patients will enter the office through the waiting room. We will room well and sick patients in different rooms to ensure continued separation. We ask that you try to limit bringing siblings to appointments. Masks or face coverings must be worn by everyone over the age of 2 years old during the entire office visit. 

We have removed all toys and books from our waiting room and exam rooms. We are maintaining our rigorous cleaning and ensuring all surfaces are wiped down after every use. We encourage everyone to do their part to stop the spread of infection including frequent hand washing, covering mouth while coughing or sneezing, and distancing themselves from others especially when ill.

If you have been exposed to a confirmed case of COVID-19, have traveled to a high-risk country in the last 14 days, or believe you or your child may have COVID-19 (fever, cough, shortness of breath); please do not enter our office. We are unable to test for COVID-19 in our office at this time. We do not have the proper equipment or ventilation needed to be able to perform such a test. However, if you have any of these concerns please contact our office who will be triaging phone calls. If we feel you meet criteria, we will contact the health department to get authorization needed for testing to be a done at a local facility.

We appreciate your patience and understanding during this rapidly changing time. We will continue to update our policies and practices to ensure the safety of our patients, families, and staff. The CDCs website is a great source of information: We are all in this together and we are here for you.
