Those with allergies in the Delaware area often find the fall season especially challenging due to the increase in weed pollen throughout the region. According to the Asthma and Allergy Foundation of America, the Columbus region sees an above average influx in ragweed during the fall months. Our new office will provide allergy and asthma care to patients looking for relief.

Before our board-certified allergist develops a personalized treatment plan, patients will undergo allergy testing to understand which allergens their body is sensitive to. We offer a full range of allergy and asthma testing, including allergy skin testing, stinging insect testing, food challenges, and pulmonary function testing. While avoidance of allergens is best, if that’s not enough to control symptoms, our doctors can recommend treatment plans including inhaled and oral medications, biologics, and immunotherapy (allergy shots).

If you currently get shots at another shot room and are interested in transferring your shot vials to the new Delaware office, please talk to your shot room nurse or call 800.999.1249 and choose option #3 during the automated message.

Our new Delaware phone number is: 740.371.9721
