About Us

Allergy, Asthma & Sinus Practice has been offering allergy and asthma services in the Newburgh, New York, and the Hudson Valley area since 2004. Dr. Witkowska has been fellowship trained in allergy and asthma treatments for both adult and pediatric patients. We do allergy skin testing for airborne allergens, foods, insect venom, and medications, as well as patch, anesthetic, and ingestion testing for prolonged-contact reactions. Our asthma services include spirometry to test lung function, and more.

Mission Statement

I treat my patients as I would like to be treated. I discuss their condition with them and perform those tests that seem to be appropriate, so that I can understand what is troubling them.

I tell them, with compassion, what I think is wrong and what can be done. I try to be mindful of the various financial and time constraints that patients have and I try to offer practical advice that will help them achieve better health.

I am dedicated to helping my fellow man by being a skilled physician who stays abreast of the latest research and other advances in my field.

Dr. Witkowska provides allergy services in Rockland County, New Jersey, and the upper Manhattan area for new patients on Mondays, Tuesdays, and Saturdays. Please contact us for more details.
