6/29/2020 Update -  Green Phase  Coronavirus (COVID-19) :

Our office continues to require anyone entering our office -ages 2 and older - wear a mask during the green phase.  We continue to practice social distancing and routinely sanitize our waiting area and exam rooms.

1.  For all allergy injection patients and patients who have an  office appointment, we ask that you come alone if you are 18 and over.  If the patient is under 18 we require that only one parent/guardian bring the child. 
3.  To help with social distancing, our allergy injection patients may wait their 30 minutes in an exam room or the hall.
4.  Reminder - call before coming to the office if you feel sick, have an increase in temperature, are coughing or SOB, traveled outside of the USA, or have come in contact with someone with known COVID-19.

We encourage our patients to review recommendations put forth by the CDC  


Feel free to contact our office with any questions!
