"Allergic disease, such as food and environmental allergies and asthma is hereditary.  As a result, I treat and care for multiple family members allowing me to build a close relationship with my patients.  It is important to empower my families through education so they understand their specific allergic disease.  My greatest reward is seeing my patients live a healthy and normal life despite suffering from allergies and asthma."
