    Dr. Dziewa knew right away that I didn’t have any allergies and she was right. Her assistant tested me and I tested negative for allergies. Dr. Dziewa gave me a different diagnosis and how to manage it. She also said if my sensitive nose continues to bother me that I should see an ENT. Dr. Dziewa was very kind and professional.

    My visit with Iwona Dziewa was exceptional. She took the time to review how to use an epipen and my nasal spray even though I've had them for years. I was not using the nasal spray correctly so its great that she continues to spend time on education. She told me exactly when I should go to the hospital for my allergies as it is not always required right away. She was thorough with her exam and educational materials.

    I found Dr. Dziewa very thorough and knowledgeable. I was just surprised that she didn't seem interested in looking at my hives, directly, which I had at the time. She seemed to be satisfied just looking at pictures. I practically forced her to look at the hives for herself.
