My sister's son had a persisting allergic and asthma problem that really made childhood difficult. This was the case until they had Dr. Ziegner for his allergist and doctor. From a wallflower who was always excused of any activity, he now enjoys whatever fun his peers are getting into. I've taken Jake to the Riviera Allergy Medical Center several times and every visit was very pleasant. Dr. Z is very professional yet warm and caring, she demonstrates a high degree of expertise when answering questions and always takes the time to discuss things into detail which makes parents like my sister love working with her to ensure Jake grows healthy. Highly recommended.
