Practice Philosophy

We specialize in adult and pediatric allergy and asthma. We are dedicated to providing compassionate, high quality medical care to patients of all ages.

We emphasize open lines of communication in our practice. To improve the quality of medical care, we encourage questions and enjoy teaching our patients about allergies and asthma. We are thorough in providing written instructions and informational brochures to help our patients improve rapidly and to get the most out of their medical care. We will communicate with your primary care physician about our findings and recommendations.

Our goal is to help patients fully participate in daily activities at work, school or sports without allergy or asthma getting in the way. Asthma and allergies should not cause absenteeism or interfere with sleep.

Our staff works as a team. Our staff is chosen for their warmth, maturity, and concern for patients. We all take pride in providing a caring environment and building a strong doctor-patient relationship.
