“Allergies can have a worse impact on patients’ day to day lives than more serious diseases. Their problems often cannot be solved by taking over-the-counter medications. My goal is always optimal health for my patients, by helping them to understand what triggers their symptoms and how to control them. I partner with my patients to develop an individualized treatment plan that considers their needs, preferences, and lifestyles. I believe trust and honesty are key elements in the patient-physician relationship, and I work closely with my patients to keep them well.”
