Important COVID-19 Update from California Allergy and Asthma Medical Group

Dear Patients,

The COVID-19 pandemic has affected all our lives in unprecedented ways. At California Allergy and Asthma Medical Group, we are committed to your care and safety.

Telemedicine visits are now available for our patients. The need for in-office visits will be evaluated on a case-by-case basis for new and follow-up patients.

Allergy shots will continue in the office. After shots, patients will wait for the required 30 minutes either in the spacious area outside the office or in their cars. After 30 minutes, those waiting outside will come in to be checked before they leave. Those waiting in their cars will text or call us that they are fine before leaving.

Effective March 28th, Saturdays will be closed ..... until further notice.

As the situation changes, we will update this page.
